Safety Labels 5

Important Safety Information

Your ATV can provide many years of service and pleasure if you take responsibility for your own safety and understand the challenges you can meet while riding.

There is much that you can do to protect yourself when you ride. You'll find many helpful recommendations throughout this manual. The following are a few that we consider to be most important.

Follow the Age Recommendation

The minimum recommended age for this ATV model is 16. Children under age 16 should never operate this vehicle. Refer to the age warnings provided in this manual and on the ATV.

Always Wear a Helmet

It's a proven fact: helmets significantly reduce the number and severity of head injuries. So always wear an approved motorcycle helmet. We also recommend that you wear eye protection, sturdy boots, gloves, and other protective gear (page 26).

Never Carry a Passenger

Your ATV is designed for one person only. There are no handholds, footrests, or seat for a second person, so never carry a passenger. A passenger could interfere with your ability to move around to maintain your balance and control of the ATV.

Ride Off-road Only

Your ATV is designed and manufactured for off-road use only. The tires are not made for pavement, and the ATV does not have turn signals and other features required for use on public roads. If you need to cross a paved or public road, get off and walk your ATV across.

Take Time to Learn & Practice

Even if you have ridden other ATVs, take time to become familiar with how this ATV works and handles. Practice in a safe area until you build your skills and get accustomed to the ATV's size and weight.

Because many crashes involve inexperienced or untrained riders, we urge all riders to take a ATV operator course approved by the ATV Safety Institute (ASI). See page 28.

Contact an authorized ATV dealer or call 1-800-887-2887 (USA only) to find out about the training courses nearest you.

Be Alert for Off-road Hazards

The terrain can present a variety of challenges when you ride off-road. Continually “read” the terrain for unexpected turns, drop-offs, rocks, ruts, and other hazards. Always keep your speed low enough to allow time to see and react to hazards.

Important Safety Information

Ride within Your Limits

Pushing limits is another major cause of ATV crashes. Never ride beyond your personal abilities or faster than conditions warrant. Remember that alcohol, drugs, fatigue, and inattention can significantly reduce your ability to make good judgments and ride safely.

Don't Drink and Ride

Alcohol and riding don't mix. Even one drink can reduce your ability to respond to changing conditions, and your reaction time gets worse with every additional drink. So don't drink and ride, and don't let your friends drink and ride either.

Keep Your Honda in Safe Condition

It's important to keep your ATV properly maintained and in safe riding condition. Having a breakdown can be difficult, especially if you are stranded off-road far from your base. To help avoid problems, inspect your ATV before every ride and perform all recommended maintenance.

Your ATV comes with a hang tag and several labels containing important safety information. Anyone who rides the vehicle should read and understand this information before riding.

The labels should be considered permanent parts of the vehicle. If a label comes off or becomes hard to read, contact your dealer for replacements.

WARNING Improper ATV use can result in SEVERE INJARY or DEATH ALWAYS USE AN APPROVED HELMET AND PROTECTIVE GEAR NEVER USE ON PUBLIC ROADS NEVER CARRY PASSENGERS NEVER USE WITH DRUGS OR ALCOHOL. NEVER operates: • without proper training or instruction • all speeds too fast for your skills or the conditions • on public roads - a collision can occur with another vehicle • with a passenger - passengers affect balance and clearing and increase risk of losing control ALWAYS: • use proper riding techniques to avoid vehicle overturns on hills and rough terrain and in turns • avoid paved outflares - pavement may seriously affect handling and control LOCATE AND READ OWNER'S MANUAL. FOLLOW ALL INSTRUCTIONS AND WARNINGS.

Before you ride your ATV for the first time, we urge you to:

  • Read this owner's manual and the labels on your ATV carefully.
  • Make sure you understand all the safety messages.
  • Know how to operate all the controls.

Before each ride, be sure:

  • You feel well and are in good physical and mental condition.
  • You are wearing an approved motorcycle helmet (with chin strap tightened securely), eye protection, and other protective clothing.
  • You don't have any alcohol or drugs in your system.

Protective Apparel

For your safety, we strongly recommend that you always wear an approved motorcycle helmet, eye protection, boots, gloves, long pants, and a long-sleeved shirt or jacket whenever you ride.

Although complete protection is not possible, wearing proper gear can reduce the chance of injury when you ride.

Following are suggestions to help you choose the proper gear.

Helmet and Eye Protection

Your helmet is your most important piece of riding gear because it offers the best protection against head injuries. A helmet should fit your head comfortably and securely.

An open-face helmet offers some protection, but a full-face helmet offers more. Regardless of the style, look for a DOT (Department of Transportation) sticker on any helmet you buy (USA only). Always wear a face shield or goggles to protect your eyes and help your vision.

WARNING

Operating this ATV without wearing an approved motorcycle helmet, eye protection, and protective clothing could increase your chances of severe injury or death in the event of an accident.

Always wear an approved motorcycle helmet that fits properly and wear eye protection (goggles or face shield), gloves, boots, long-sleeved shirt or jacket and long pants.

Additional Riding Gear

In addition to a helmet and eye protection, we also recommend:

  • Sturdy off-road motorcycle boots to help protect your feet, ankles, and lower legs.
  • Off-road motorcycle gloves to help protect your hands.
  • Riding pants with knee and hip pads, a riding jersey with padded elbows, and a chest/shoulder protector.

Rider Training

Developing your riding skills is an on-going process. Even if you have ridden other ATVs, take time to become familiar with how this ATV works and handles. Practice riding the ATV in a safe area to build your skills. Do not ride in rough terrain until you get accustomed to the ATV's controls, and feel comfortable with its size and weight.

We urge all riders to take a ATV operator course approved by the ATV Safety Institute (ASI). For information about the ASI training course nearest you, call the national toll-free number; (800) 887-2887 (USA only).

Other riding tips can be found in the Tips & Practice Guide for the ATV Rider booklet that came with your ATV (USA only).

WARNING

Operating this ATV without proper instruction could increase your risk of an accident which could lead to serious injury or death.

Beginning and inexperienced operators should complete the certified training course offered by Honda. They should then regularly practice the skills learned in the course and the operating techniques described in the owner's manual.

Age Recommendation

The minimum recommended age for this ATV model is 16. For safety, never let children under 16 years old operate this vehicle.

WARNING

A child using an ATV that is not recommended for their age could lose vehicle control while riding, resulting in severe injury or death.

A child under 16 should never operate an ATV with engine size greater than 90cc.

No Passengers

This ATV is designed as an operator-only vehicle. The long seat is designed to allow the rider to change body position, not for carrying a passenger. Never let a passenger ride on the seat.

WARNING

Carrying a passenger on this ATV greatly reduces your ability to balance and control this ATV and could cause a crash and you or your passenger could be injured or killed.

Never carry a passenger on this ATV.

No Alcohol or Drugs

Alcohol, drugs and ATVs don't mix. Even a small amount of alcohol can impair your ability to operate an ATV safely. Likewise, drugs — even if prescribed by a physician — can be dangerous while operating an ATV. Consult your doctor to be sure it is safe to operate a vehicle after taking medication.

WARNING

Operating this ATV after consuming alcohol or drugs can seriously affect your judgement, cause you to react more slowly, affect your balance and perception, and result in serious injury or death.

Never consume alcohol or drugs before or while operating this ATV.

Before each ride, it's important to inspect your ATV and make sure any problem you find is corrected. A pre-ride inspection is a must, not only for safety, but because having a breakdown, or even a flat tire, can be a major inconvenience.

If your ATV has overturned or been involved in a collision, do not ride the vehicle until it has been inspected by your dealer. There may be damage or other problems you cannot see.

WARNING

Improperly maintaining this ATV or failing to correct a problem before riding can cause a crash in which you can be seriously hurt or killed.

Always perform a pre-ride inspection before every ride and correct any problems.

Pre-ride Inspection

Check the following items before you get on the ATV:

Engine Oil

Check the level and add oil if needed (page 91). Check for leaks.

Transmission Oil

Check the level and add oil if needed (page 97). Check for leaks.

Radiator Coolant Check the coolant level and add coolant if needed (page 101). Check for leaks.

(cont'd)

Is Your ATV Ready to Ride?

Fuel Check the level and add fuel (page 86) if needed. Also make sure the fuel fill cap is securely fastened. Check for leaks.

Tires Use a gauge to check the air pressure. Adjust if needed. Also look for signs of damage or excessive wear (page 139).

Drive Chain Check the condition and slack. Adjust and lubricate if needed. Also check the chain slider and chain roller for wear and replace if needed (page 147).

Guards Check for damage or looseness (page 146).

Nuts & Bolts Check the wheels to see that the axle nuts are tightened. Use a wrench to make sure all accessible nuts, bolts, and fasteners are tight.

Underbody & Exhaust System Check for, and remove, any dirt, vegetation or other debris that could be a fire hazard or interfere with the proper operation of the vehicle.

Leaks, Loose Parts Walk around your ATV and look for anything that appears unusual, such as a leak or loose cable.

Cable Check the cable housings for wear. Check the fittings for looseness. Replace or tighten as needed.

Lights Make sure the headlight, brake light and taillight are working properly.

Check these items after you get on the ATV:

Throttle Check the freeplay and adjust if needed. Press the throttle to make sure it moves smoothly without sticking, and snaps shut automatically when it is released, in all steering positions (page 110).

Brakes Squeeze the front brake lever and step on the rear brake pedal to check that the controls operate normally. Make sure there is no brake fluid leakage (page 129).

Clutch Lever/Parking Brake Lever Check for smooth operation and adjust if needed (page 112).

Headlight and Check for proper function (page 20). Headlight Dimmer Switch

Engine Stop Switch Check for proper function (page 19).

Steering Check that the wheels turn properly as you steer the handlebar. Move the handlebar right and left and check that there is no excessive backlash.

Remember, be sure to take care of any problem you find, or have your dealer correct it before you ride.

Your Honda was designed as a rider-only ATV. It was not designed to carry a passenger or cargo. A passenger or cargo could interfere with your ability to move around to maintain your balance and control of the ATV.

In addition, exceeding the weight limits or carrying an unbalanced load can seriously affect your ATV's handling, braking and stability. Adding accessories or making modifications that change this ATV's design and performance can also make it unsafe. Also, the weight of any accessories will reduce the maximum load the ATV can carry.

More specific information on load limits, accessories, and modifications follows.

Loading

How much weight you put on your ATV, and how you load it, are important to your safety. If you decide to carry cargo, you should be aware of the following information.

WARNING

Overloading, improper loading, or carrying a passenger can cause a crash and you can be seriously hurt or killed.

Follow all load limits and other loading guidelines in this manual.

Load Limits

Following are the load limits for your ATV:

There is a limit to how much weight can be carried on your ATV.

The following load limit applies to standard equipment only. Modifying your ATV, using non-standard equipment, or riding on terrain that is not flat and smooth could further reduce these limits.

maximum weight capacity 243 lb (110 kg) (includes the weight of the rider, all cargo, and accessories.)

The weight of added accessories will reduce the maximum cargo weight you can carry.

Loading Guidelines

As discussed on page 34, we recommend that you do not carry any cargo on this ATV. However, if you decide to carry cargo, ride at reduced speeds and follow these common-sense guidelines.

Carrying cargo or pulling a trailer will affect how your ATV handles and greatly reduce its ability in accelerating, braking and making turns and other maneuvers.

Be sure to observe the weight limit and follow these guidelines:

  • Check that the tires are properly inflated.
  • Never ride with a passenger. The ATV is not designed to carry a passenger.
  • Do not tow another vehicle.
  • Make sure all cargo is secured before riding.
  • Never exceed the maximum weight limit.
  • Allow extra room for starting, stopping and turning whenever you carry cargo or pull a trailer.
  • Avoid riding on steep slopes when carrying cargo or pulling a trailer.
  • Never cross a slope when towing a trailer.

Modifying your ATV or using non-Honda accessories can make your ATV unsafe.

Before you consider making any modifications or adding an accessory, be sure to read the following information.

WARNING

Improper accessories or modifications can cause a crash in which you can be seriously hurt or killed.

Follow all instructions in this owner's manual regarding accessories and modifications.

Accessories

We strongly recommend that you use only Honda Genuine Accessories that have been specifically designed and tested for your ATV. Because Honda cannot test all other accessories, you must be personally responsible for proper selection, installation, and use of non-Honda accessories.

Check with your dealer for assistance and always follow these guidelines:

  • Make sure the accessory does not obscure any lights, reduce ground clearance, limit suspension travel or steering travel, or interfere with operating any controls.
  • Make sure the accessory does not interfere with your ability to shift body position on the seat or operate hand and foot controls.
  • Do not add any electrical equipment that will exceed the vehicle's electrical system capacity (page 200). A blown fuse can cause a loss of lights or engine power (page 187).

Modifications

We strongly advise you not to remove any original equipment or modify your ATV in any way that would change its design or operation. Such changes could seriously impair your ATV's handling, stability, and braking, making it unsafe to ride.

We also advise you not to make any modifications or remove any equipment (such as the USDA qualified spark arrester or emission control system components) that would make your ATV illegal in your area.

Removing or modifying your lights, exhaust system, emission control system, or other equipment can also make your ATV illegal.

This section gives basic riding instructions, including how to start and stop your engine, how to use the throttle and brakes, and what to do when you're through riding.

To protect your new engine and enjoy optimum performance and service life, refer to Break-in Guidelines (page 201).

Even if you have ridden other ATVs, take time to become familiar with how this ATV works and handles. Practice in a safe area until you build your skills and get accustomed to the ATV's size and weight.

Off-road Use Only

Your ATV and its tires are designed and manufactured for off-road use only, not for pavement. Riding on pavement can affect handling and control. You should not ride your ATV on pavement.

WARNING

Operating this ATV on paved surfaces may seriously affect handling and control of the ATV, and may cause the vehicle to go out of control.

Never operate the ATV on any paved surfaces, including sidewalks, driveways, parking lots and streets.

When riding off-road, also remember to always obey local off-road riding laws and regulations. Obtain permission to ride on private property. Avoid posted areas and obey “no trespassing” signs.

You should never ride your ATV on public streets, roads or highways, even if they are not paved. Drivers of street vehicles may have difficulty seeing and avoiding you, which could lead to a collision. In many states it is illegal to operate ATVs on public streets, roads and highways.

WARNING

Operating this ATV on public streets, roads or highways could cause you to collide with another vehicle.

Never operate this ATV on any public street, road or highway, even a dirt or gravel one.

Keep Hands and Feet on Controls

Always keep both hands on the handlebars and both feet on the footpegs when riding your ATV. This is important to maintain your balance and to control the vehicle. Removing even one hand from the handlebars or one foot from the footpegs can reduce your ability to control the ATV or could cause you to lose your balance and fall off the ATV.

WARNING

Removing hands from handlebars or feet from footpegs during operation can reduce your ability to control the ATV or could cause you to lose your balance and fall off of the ATV.

Always keep both hands on the handlebars and both feet on the footpegs of your ATV during operation.

Control Speed

Riding at excessive speed increases the chance of a crash. In choosing a proper speed, you need to consider the capability of your vehicle, the terrain, visibility and other operating conditions, plus your own skills and experience.

WARNING

Operating this ATV at excessive speeds increases your chances of losing control of the ATV, which can result in an accident.

Always go at a speed that is proper for your vehicle, the terrain, visibility and other operating conditions, and your experience.

Use Care on Unfamiliar or Rough Terrain

Before riding in a new area, always check the terrain thoroughly. Don't ride fast on unfamiliar terrain or when visibility is limited. (It's sometimes difficult to see obstructions like hidden rocks, bumps, or holes in time to react.)

WARNING

Failure to use extra care when operating this ATV on unfamiliar terrain could result in the ATV overturning or going out of control.

Go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to changing terrain conditions when operating the ATV.

Never ride past the limit of visibility. Maintain a safe distance between your ATV and other off-road vehicles. Always exercise caution, and use extra care on rough, slippery and loose terrain.

WARNING

Failure to use extra care when operating on excessively rough, slippery or loose terrain could cause loss of traction or vehicle control, which could result in an accident, including an overturn.

Do not operate on excessively rough, slippery or loose terrain until you have learned and practiced the skills necessary to control the ATV on such terrain. Always be especially cautious on these kinds of terrain.

Do Not Perform Stunts

You should always operate your ATV in a safe and reasonable manner. When riding, always keep all four wheels on the ground.

WARNING

Attempting wheelies, jumps, and other stunts increases the chance of an accident, including an overturn.

Never attempt stunts, such as wheelies or jumps. Don't try to show off.

Starting & Stopping the Engine

Always follow the proper starting procedure described below.

For your safety, avoid starting or operating the engine in an enclosed area such as a garage. Your ATV's exhaust contains poisonous carbon monoxide gas which can collect rapidly in an enclosed area and cause illness or death.

Your ATV is equipped with a gear position starter cut-off system. The engine cannot be started if the transmission is in gear — unless the clutch lever is pulled in.

  4. Press the start button for 5 seconds.
  5. Wait 10 seconds, then turn the engine stop switch to RUN ( ).
  6. Repeat the "Normal Air Temperature" starting procedure, but don't use the choke.

How to Stop the Engine

Normal Engine Stop

To stop the engine, make sure the transmission is in neutral by checking that the neutral indicator light is on, then turn the ignition switch OFF (O).

If your ATV is stopped with the engine stop switch OFF (☒) and the ignition switch ON (I), the battery will discharge.

The engine stop switch should normally remain in the RUN ( ) position even when the engine is OFF.

Emergency Engine Stop

To stop the engine in an emergency, use the engine stop switch. To operate, slide the switch to the OFF (☒) position.

The shift lever is located near the left footpeg. One full stroke of the shift lever shifts the transmission to the next higher or lower gear in the shifting sequence. The shift lever automatically returns to the horizontal position when released.

Your ATV has five forward gears (1, 2, 3, 4 and 5). To shift the transmission, pull in the clutch lever, then operate the shift lever as follows.

To upshift to a higher gear, put the toe of your boot under the shift lever and raise it one full stroke. To downshift, step on the shift lever and depress it one full stroke.

After starting the engine and letting it warm up, follow these procedures:

  1. With the transmission in neutral, depress and hold down the rear brake pedal. Release the parking brake (page 23).

  2. With the throttle closed while the engine is idling, pull in the clutch lever and depress the shift lever to shift into 1st gear.

  3. Release the rear brake pedal, gradually release the clutch lever, and increase engine speed by gradually opening the throttle.
  4. When the speed increases, close the throttle, pull in the clutch lever, shift to 2nd gear by raising the shift lever, and gradually release the clutch lever while gradually opening the throttle.
  5. Repeat this sequence to progressively upshift to 3rd, 4th and 5th (top) gear.
  6. To downshift, reverse this sequence. Remember to close the throttle each time you shift to the next lower gear.

Learning when to shift gears comes with experience. Keep the following tips in mind:

  • As a general rule, shift while moving in a straight line.
  • Close the throttle and pull the clutch lever in completely before shifting. Improper shifting may damage the engine, transmission, and drive train.
  • Upshift to a higher gear or reduce throttle before engine rpm (speed) gets too high. Learn the relationship between engine sound and the normal shifting points.
  • Downshift to a lower gear before you feel the engine laboring (lugging) at low rpm.
  • Avoid downshifting to help slow your ATV when engine rpm is high. Downshifting when engine speed is near its allowable maximum may over-rev the engine and possibly cause damage.
  • To prevent transmission damage, do not coast or tow the ATV for long distances with the engine off.

Ride in the highest gear that lets the engine run and accelerate smoothly.

This will give you good fuel economy and effective emissions control.

Your ATV is equipped with disc braking systems which are hydraulically activated. Depressing the brake pedal applies the rear disc brake. Operating the brake lever applies the two front disc brakes.

As a general rule, the front braking system provides about 70 percent of total stopping power.

For full braking effectiveness, use both the pedal and lever simultaneously. Using both braking systems will stop your ATV faster with greater stability.

To slow or stop, apply the brake lever and brake pedal smoothly, while downshifting to match your speed.

Gradually increase braking as you feel the brakes slowing your speed. The increase in engine compression from downshifting will help slow your ATV.

For maximum braking, close the throttle and firmly apply the brake lever and pedal controls.

Applying the brakes too hard may cause the wheels to lock and slide, reducing control of your ATV. If this happens, release the brake controls, steer straight ahead until you regain control, then reapply the brakes more gently.

When possible, reduce your speed or complete braking before entering a turn. Avoid braking or closing the throttle quickly while turning. Either action may cause one or more wheels to slip and reduce your control of your ATV.

Your ability to brake in a turn and to brake hard in an emergency situation are important riding skills.

When descending a long, steep grade, use engine compression braking by downshifting, with intermittent use of both brakes. Continuous brake application can overheat the brakes and reduce their effectiveness.

To prevent stalling the engine, pull the clutch lever/parking brake lever in before coming to a complete stop.

Riding with your foot resting on the brake pedal or your hand on the brake lever may overheat the brakes, reducing effectiveness.

For information on how to apply the brakes in various riding situations, see the following section, Riding Your ATV.

Making Turns

Learn how to turn your ATV properly. Practice the techniques outlined in this section on level ground and at low speeds until you are confident in making turns.

WARNING

Turning improperly can make the ATV go out of control, causing a collision or overturn.

  • Always follow proper procedures for turning as described in this owner's manual.
  • Practice turning at low speeds before attempting to turn at faster speeds.
  • Do not turn at excessive speeds.

Honda TRX450R (2013) - WARNING - 1

natural_image Two line drawings of a person riding a high kick in a desert landscape, showing dynamic motion (no text or symbols)

Lean your body to the inside of a turn and forward.

To make a turn on level ground: Steer the handlebar and lean your body toward the inside of the turn. Leaning helps balance the vehicle, and it feels more comfortable. Leaning into a turn is an important technique to master in riding an ATV.

To make a sharp turn at low speed: It helps to shift your body slightly forward on the seat, and lean inside, as you steer the handlebar. Shifting weight forward allows the rear wheels to turn easier, and it also improves front-wheel steering.

To make a turn from a full stop: Apply the throttle gradually when you turn and start up at the same time. Remember to shift your body forward to make sharp low-speed turns and whenever you turn while accelerating from a full stop.

Skidding or Sliding

The terrain surface can be a major factor affecting turns. Skidding during a turn is more likely to occur on slippery surfaces, such as snow, ice, mud and loose gravel. If you skid on ice, you may lose all directional control. To avoid skidding on slippery terrain, keep your speed low and ride with caution.

WARNING

Skidding or sliding improperly may cause you to lose control of this ATV. You may also regain traction unexpectedly, which may cause the ATV to overturn.

Learn to safely control skidding by practicing at low speeds and on level, smooth terrain.

If your ATV skids sideways during a turn, steer in the direction of the skid. Avoid hard braking or accelerating until you have regained directional control.

Riding Up Hills

The ATV's ability to safely climb hills largely depends on the rider's skill and judgment. Begin by practicing on smooth, gentle slopes. As you gain experience, you'll learn the hazards and your own limitations. You may then proceed to ride on more difficult terrain. However, you must be able to decide which hills or hazards might cause the ATV to overturn. Avoid excessively steep hills.

WARNING

Operating on excessively steep hills can cause the vehicle to overturn more easily than operating on level surfaces or small hills.

Never operate the ATV on hills too steep for the ATV or for your abilities.

When climbing hills, you must shift weight toward the front wheels to help keep them on the ground. To do this, shift your body slightly forward on the seat and lean forward. For greater weight shift, move your body farther forward and lean forward.

WARNING

Climbing hills improperly could cause loss of control or cause the ATV to overturn.

Always follow proper procedures for climbing hills as described in this owner's manual.

Honda TRX450R (2013) - WARNING - 1

natural_image Line drawing of a person riding a small off-road vehicle with visible wheels and motion blur (no text or symbols)

Shift weight forward when climbing hills.

• Always check the terrain carefully before you start up any hill.
- Never climb hills with excessively slippery or loose surfaces.
- To climb a hill, take a running start in an appropriate gear and speed for the conditions. Maintain a steady speed as you ascend the hill.
- Never open the throttle suddenly or make sudden gear changes. The ATV could flip over backward.
- Never go over the top of any hill at high speed. An obstacle, a sharp drop, or another vehicle or person could be on the other side of the hill.

Stalling the ATV and/or Rolling Backwards:

If you incorrectly estimate climbing capability or terrain conditions, the ATV may not have enough power or traction to continue uphill. If this happens, the ATV can stall and/or roll backwards.

WARNING

Stalling, rolling backwards or improperly dismounting while climbing a hill could result in the ATV overturning.

Always follow proper procedures for climbing a hill as described in this owner's manual.

What to do if the ATV stalls or rolls backwards when climbing a hill:

If you are about to lose all forward speed:

  1. Using the front and rear brakes together, bring the ATV to a stop with the vehicle pointed straight uphill.
  2. Get off the ATV while you continue holding the brakes.
  3. Shift into neutral, set the parking brake and turn the engine off.
  4. Then assess the situation.

If the ATV starts rolling backwards before you begin braking:

  1. Keep your weight uphill.
  2. Carefully apply the front brakes first, then carefully apply the rear brake. Do not apply either brake abruptly if you are rolling backwards, or the vehicle may overturn.

If the ATV continues sliding backwards:

After you've applied the brakes, get off and away from the vehicle.

What to do after the ATV has stalled or rolled backwards:

If the hill is too steep or too slippery, or if you have any doubt whether you can safely walk the ATV back down the hill, leave the vehicle where it is and get help. If possible, block the wheels so the vehicle doesn't roll backwards.

If the hill is not too steep and you have good footing, you may be able to walk the ATV back down the hill. Make sure your intended path is clear in case you lose control of the ATV.

Honda TRX450R (2013) - WARNING - 1

natural_image Line drawing of a person riding a small vehicle with motion lines indicating speed (no text or symbols)

Be sure your legs are clear of the wheels.

Honda TRX450R (2013) - WARNING - 2

natural_image Line drawing of a person standing on a wheeled off-road vehicle (no text or symbols)

Body position for backing down a hill.

  1. Stand with your body facing downhill, beside the vehicle so you can reach the front brake lever with your left hand.
  2. Be sure your legs are clear of the wheels.
    Check your footing.
  3. Slowly and carefully back the ATV down the hill using the front brake lever to control speed.
  4. If you lose control of the ATV, for your safety, get away from the vehicle.

Riding Down Hills

It's usually advisable to descend hills with the ATV pointed straight downhill. Avoid angles that would cause the vehicle to lean sharply to one side.

WARNING

Going down a hill improperly could cause loss of control or cause the ATV to overturn.

Always follow proper procedures for going down hills as described in this owner's manual.

Honda TRX450R (2013) - WARNING - 1

natural_image Line drawing of a person riding a multi-rotor vehicle in motion, kicking up dust (no text or symbols)

On downhills, shift your weight back.

As you approach a downhill, stop and survey the terrain below. Never ride past the limit of your visibility. Never go down a hill at high speed.

When you've selected a safe downhill path, shift into a lower gear, shift your weight back with your arms extended and braced against the handlebar, then go down slowly with the throttle closed.

Use mainly the rear brake to control speed. Avoid using either the front brake or rear brake hard or abruptly when riding down hills.

Remember, braking effectiveness is reduced on any hill with a loose surface.

Crossing or Turning on Hills or Slopes

Riding on hills or slopes is different from riding on level terrain. Be careful when riding on any hill. Make sure that you practice on gentle, smooth slopes before attempting to ride on steeper or more difficult terrain.

WARNING

Improperly crossing hills or turning on hills could cause loss of control or cause the ATV to overturn.

Always follow proper procedures for crossing or turning on slopes as described in this owner's manual. Avoid crossing steep hills if possible.

Crossing Hills or Slopes

  • To maintain balance and stability when riding across a slope, you need to shift weight toward the uphill side of the vehicle. To do this, move your body off the center of the seat and lean toward the uphill side.
  • On a slippery or loose surface, you may also need to steer slightly uphill to maintain a straight course across the slope.
  • Avoid crossing hills that are excessively steep, slippery or rough.

Honda TRX450R (2013) - Crossing Hills or Slopes - 1

natural_image Line drawing of a person riding a multi-axle vehicle on a dirt road (no text or symbols)

Shift weight uphill when crossing slopes.

Making Turns on Slopes

  • Compared to riding on level ground, you may need to shift more weight and lean more when making turns on slopes.
  • Do not make turns on any slopes until you have first mastered the techniques for making turns on level terrain.

Riding Over Obstacles

Before operating in a new area, check for obstacles. Watch out for bumps, rain ruts, potholes and other obstacles in the terrain. When you approach any obstacle, reduce your speed and be prepared to stop.

Never try to ride over large obstacles, such as large rocks or fallen logs.

WARNING

Improperly operating over obstacles could cause loss of control or a collision and could cause the ATV to overturn.

When you go over obstacles, always follow proper procedures as described in this owner's manual.

Riding Through Water

Your ATV is designed to travel through water up to approximately 10 inches (254 mm) deep. Before crossing a stream, make sure the water is not too deep or flowing too fast.

WARNING

The ATV tires have some ability to float. Operating this ATV through deep or fast-flowing water may cause a loss of traction and loss of control, which could lead to an accident.

Never operate this ATV in fast-flowing water or in water deeper than that specified in this owner's manual.

  1. Choose a path where both banks have gradual slopes.
  2. Proceed through the water at a slow, steady speed.
  3. Watch out for submerged obstacles and slippery rocks.
  4. Avoid getting the spark plug or air cleaner wet, as this would cause the engine to stop.
  5. After leaving the water, always test both the front and rear brakes.

- Riding through water can make the brakes less effective than normal, and may reduce stopping ability.

- If necessary, apply the brakes repeatedly until they dry out and operate normally.

Parking

  1. Look for level parking area. Make sure the ground surface is firm.
  2. After bringing your ATV to a stop, hold the brakes while you shift into neutral.
  3. Set the parking brake.
  4. Turn the ignition switch OFF (O).
  5. If you're finished riding for the day, turn the fuel valve OFF.

If it is necessary to start the engine when your ATV in gear and is stopped on a grade, rock the vehicle back and forth to allow shifting the transmission into neutral.

Parking on a Steep Incline or a Loose or Slippery Surface

If you must park your ATV on a steep incline or loose or slippery surface, use the following procedure:

  1. While holding the brakes, set the parking brake.
  2. Turn the ignition switch OFF (O) and release the brakes.
  3. If the ATV begins to move, either while sitting on it or after you dismount, find a better parking location.
  4. If rocks or other objects are available, you can block the wheels as shown for additional security.

The Importance of Maintenance

A well-maintained ATV is essential for safe, economical, and troublefree riding. It will also help reduce air pollution. Careful pre-ride inspections and good maintenance are especially important because your ATV is designed to be ridden over rough off-road terrain.

To help you properly care for your ATV, this section of the manual provides a Maintenance Schedule. The service intervals in this schedule are based on average riding conditions.

More frequent service is needed if you subject your ATV to severe use or ride in unusually wet or dusty areas.

WARNING

Improperly maintaining this ATV or failing to correct a problem before you ride can cause a crash in which you can be seriously hurt or killed.

Always follow the inspection and maintenance recommendations and schedules in this owner's manual.

Frequent servicing of the air cleaner is especially important to help you avoid a possible costly engine repair.

If your ATV overturns or is involved in a crash, be sure your dealer inspects all major parts, even if you are able to make some repairs.

This section includes instructions on how to perform some important maintenance tasks. If you have basic mechanical skills, you can perform many of these tasks with the tools provided with your ATV.

Other tasks that are more difficult and require special tools are best performed by professionals. Removing the wheels should normally be handled only by a Honda technician or other qualified mechanic. Instructions are included in this manual only to assist in emergency service.

Some of the most important safety precautions follow. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you should perform a given task.

WARNING

Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed.

Always follow the procedures and precautions in this owner's manual.

Important Safety Precautions

- Make sure the engine is off before you begin any maintenance or repairs. This will help eliminate several potential hazards:

Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you operate the engine.

Burns from hot ATV parts. Let the engine and exhaust system cool before touching.

Injury from moving parts. Do not run the engine unless instructed to do so.

- Read the instructions before you begin, and make sure you have the tools and skills required.

- To reduce the possibility of a fire or explosion, be careful when working around gasoline. Use only non-flammable solvent, not gasoline, to clean parts. Keep cigarettes, sparks, and flames away from all fuel-related parts.

Remember that your Honda dealer knows your ATV best and is fully equipped to maintain and repair it. To ensure the best quality and reliability, use only new Honda Genuine Parts or other equivalents for repair and replacement. If you have the tools and skills required for additional maintenance jobs, you can purchase an official Honda Service Manual (page 210).

The required Maintenance Schedule that follows specifies how often you should have your ATV serviced, and what things need attention. It is essential to have your ATV serviced as scheduled to maintain safe, dependable performance and proper emission control.

The service intervals in this Maintenance Schedule are based on average riding conditions. Some items will need more frequent service if you ride in unusually wet or dusty areas or at full throttle. Consult your dealer for recommendations applicable to your individual needs and use.

Some items in the Maintenance Schedule can be performed with basic mechanical skills and hand tools. Procedures for these items are provided in this manual. Other items involve more extensive procedures and may require special training, tools, and equipment. We recommend that you have your dealer perform these tasks unless you have advanced mechanical skills and the required tools and equipment. Procedures for such items in this schedule are provided in an official Honda Service Manual available for purchase (page 210).

If you do not feel capable of performing a given task or need assistance, remember that your Honda dealer knows your ATV best and is fully equipped to maintain and repair it. If you decide to do your own maintenance, use only Honda Genuine Parts or their equivalents for repair or replacement to ensure the best quality and reliability.

Perform the pre-ride inspection (page 31) and owner maintenance on this section at each scheduled maintenance period.

Fuel Recommendation

type premium unleaded
pump octane number 91(or higher)

Use only premium unleaded fuel in your Honda. If you ride your Honda in a country where leaded fuel might be available, take precautions to use only unleaded fuel.

Your engine is designed to use any unleaded premium gasoline that has a pump octane number of 91 or higher. Gasoline pumps at service stations normally display the pump octane number. For information on the use of oxygenated fuels, see page 207.

Use of lower octane gasoline can cause persistent “pinging” or “spark knock” (a loud rapping noise) which, if severe, can lead to engine damage. Light pinging experienced while operating under a heavy load, such as climbing a hill, is no cause for concern.

If pinging or spark knock occurs at a steady engine speed under normal load, change brands of gasoline. If pinging or spark knock persists, consult your dealer.

Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt, dust, or water in the fuel tank.

Fuel Capacity

Fuel tank capacity, including reserve:

2.72 US gal (10.3 ℓ)

Reserve capacity:

0.79 US gal (3.0 ℓ)

The tank should be refilled as soon as possible after switching to reserve, and the fuel valve should be returned to the ON position after refueling to avoid running out of fuel with no reserve.

Refueling Procedure

Refer to Safety Precautions on page 73.

(1) (2) (3) (4)

(1) fuel fill cap
(2) breather tube

(3) handlebar cover hole

(4) filler neck

  1. To open the fuel fill cap (1), turn it counterclockwise.
  2. Pull the breather tube (2) out of the handlebar cover hole (3).
  3. Add fuel until the level reaches the bottom of the filler neck (4).
    Avoid over filling the tank. There should be no fuel in the filler neck.

WARNING

Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel.

  • Stop the engine and keep heat, sparks and flame away.
  • Handle fuel only outdoors.
  • Wipe up spills immediately.

  • After refueling, turn the fuel fill cap clockwise.

  • Insert the breather tube into the handlebar cover hole.
  • If the fuel valve was set to RES, turn the fuel valve ON.

If you replace the fuel fill cap, use only a Honda Genuine replacement part.

Engine oil quality is a major factor that affects both the performance and the service life of the engine.

Using the proper oil (page 89) and filter, and regularly checking, adding, and changing oil will help extend your engine's life. Even the best oil wears out. Changing oil helps get rid of dirt and deposits in the engine. Operating the engine with old or dirty oil can damage your engine. Running the engine with insufficient oil can cause serious damage to the engine and transmission.

Change the engine oil as specified in the maintenance schedule on page 76. When running in very dusty conditions, oil changes should be performed more frequently than specified in the maintenance schedule.

Your ATV's liquid cooling system dissipates engine heat through the coolant jacket that surrounds the cylinder and cylinder head.

Maintaining the coolant will allow the cooling system to work properly and prevent freezing, overheating, and corrosion.

Coolant Recommendation

Use Pro Honda HP coolant or an equivalent high quality ethylene glycol antifreeze containing corrosion protection inhibitors specifically recommended for use in aluminum engines. Check the antifreeze container label.

Use only distilled water as a part of the coolant solution. Water that is high in mineral content or salt may be harmful to the aluminum engine.

NOTICE

Using coolant with silicate inhibitors may cause premature wear of water pump seals or blockage of radiator passages. Using tap water may cause engine damage.

The factory provides a 50/50 solution of antifreeze and water in this ATV. This coolant solution is recommended for most operating temperatures and provides good corrosion protection.

Decreasing the concentration of antifreeze to less than 40% will not provide proper corrosion protection.

Increasing the concentration of antifreeze is not recommended because it decreases cooling system performance. Higher concentrations of antifreeze (up to 60%) should only be used to provide additional protection against freezing. Check the cooling system frequently during freezing weather.

Checking & Adding Coolant

Refer to Safety Precautions on page 73.

Check the engine coolant level each day before operating your ATV and add if needed.

  • Lubricate the clutch cable with a commercially available cable lubricant to prevent premature wear and corrosion.

The best way to assure proper carburetion is to see your dealer for regularly scheduled servicing, including carburetor adjustment.

Remember, idle speed adjustment is not a “cure-all” for other problems in your engine’s fuel-delivery system. Adjusting the idle will not compensate for a fault elsewhere.

The engine must be at normal operating temperature for accurate idle speed adjustment.

For information about high altitude carburetor adjustment, see page 202.

Spark Plug Recommendation

standard spark plug IFR7L11 (NGK) or VK22PRZ11 (DENSO)
for extended high speed ridingIFR8H11 (NGK) or VK24PRZ11 (DENSO)

Use only the recommended type of spark plug in the recommended heat range.

NOTICE

Using spark plug with an improper heat range can cause engine damage.

This ATV uses spark plug that have an iridium coated center electrode.

Be sure to observe the following when servicing the spark plug.

  • Do not clean the spark plug. If an electrode is contaminated with accumulated objects or dirt, replace the spark plug with a new one.
  • To check the spark plug gap, use only a “wire-type feeler gauge.” To prevent damaging the iridium coating of the center electrode, never use a “leaf-type feeler gauge.”
  • Do not adjust the spark plug gap. If the gap is out of specification, replace the spark plug with a new one.

Spark Plug Inspection & Replacement

Refer to Safety Precautions on page 73.

  1. Clean any dirt from around the spark plug base.
  2. Disconnect the spark plug cap (1). Take care to avoid damaging the spark plug wire when disconnecting the cap.
  3. Using a spark plug wrench provided in the tool kit, remove the spark plug.
  4. Inspect the electrode and center porcelain for deposits, corrosion, or carbon fouling. If the corrosion or deposits are heavy, replace the plug.
  5. Make sure that a 1.2 mm wire-type feeler gauge cannot be inserted between the spark plug gap (2). If the gauge fits in the gap, replace the plug with a new one.

DENSO: 1/2 turn after it seats.

b) Then loosen the plug.

c) Next, tighten the plug again:

1/8 turn after it seats.

NOTICE

An improperly tightened spark plug can damage the engine. If a plug is too loose, a piston may be damaged. If a plug is too tight, the threads may be damaged.

  1. Reinstall the spark plug cap. Take care to avoid pinching any cables or wires.

Valve Inspection

Refer to Safety Precautions on page 73.

Valve clearance should be:

intake: 0.006 in (0.16 mm)

exhaust: 0.011 in (0.28 mm)

Excessive clearance will cause noise. Insufficient clearance will cause loss of power and possibly damage the valves.

For those who are mechanically proficient and have the proper tools, instructions on adjusting valve clearances are given in the official Honda Service Manual. Otherwise, the valves should be adjusted by your dealer.

Refer to Safety Precautions on page 73.

The spark arrester must be serviced every 100 operating hours to maintain its efficiency.

Regular servicing prevents carbon build up (which can diminish engine performance) and also complies with USDA regulations for regular maintenance to assure proper function. The spark arrester prevents random sparks from the combustion process in your engine from reaching the environment.

  1. Allow the engine and muffler to cool.
  2. Remove the bolts (1), the muffler tail cover (2), the spark arrester (3), and the gasket (4) from the muffler (5).

Your front and rear suspension systems use springs and hydraulic damping devices that suspend your weight and most of the weight of your ATV.

The oil damper systems hydraulically control the natural compression and rebound of the suspension springs so that traction and comfort are maintained as the wheels ride over rough terrain.

The way you ride your ATV and the type of ride you want to experience can also influence your suspension needs.

You may adjust the rebound and compression damping of the front and rear suspension systems.

Suspension Adjustment

The suspension can be adjusted for rider weight and riding conditions by changing the rebound and compression damping.

The shock absorber assemblies include a damper unit that contains high pressure nitrogen gas. Do not attempt to disassemble, service, or dispose of the damper; see your dealer. The instructions found in this owner's manual are limited to adjustments of the shock assemblies.

The hydraulic disc braking systems on your ATV dissipate the heat generated by the friction of the brake pads on the brake discs as the wheels are slowed.

As the brake pads wear, the brake fluid level will drop. A leak in the system will also cause the level to drop.

There are no adjustments to perform, but fluid level and pad wear must be inspected periodically. The system must be inspected frequently to ensure there are no fluid leaks.

If the brake lever or brake pedal freeplay does not feel within the normal range while riding, check the brake pads for wear (page 133).

Worn pads should be replaced. If the pads are not worn beyond the recommended limit, there is probably air in the brake system. See your dealer to have the air bled from the system.

Brake Fluid Recommendation

brake fluid Honda DOT 4 Brake Fluid

The recommended brake fluid is Honda DOT 4 Brake Fluid, or any brake fluid of equal quality and performance. Use fresh brake fluid from a sealed container. Be sure to read the label before opening the sealed container. An opened container may be contaminated or may have absorbed moisture from the air.

Fluid Level Inspection

Refer to Safety Precautions on page 73.

If your inspection indicates a low fluid level, have your dealer add the recommended fluid.

Do not add or replace brake fluid, except in an emergency. If you do add fluid, have your dealer check the system as soon as possible.

NOTICE

Brake fluid can damage plastic and painted surfaces. Handle with care.

Wipe up spills immediately. Avoid brake fluid contact with skin or eyes. If it comes in contact with your eyes, wash them out with clean water and immediately call a doctor. If it comes in contact with your skin, wash with clean water and, if necessary, call a doctor.

To safely operate your ATV, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated.

WARNING

Using tires that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed.

Follow all instructions in this owner's manual regarding tire inflation and maintenance.

This ATV is equipped with low pressure tubeless tires. Although the tires are designed specifically for off-road use, they are not immune to punctures. Always select your riding area with care.

The following pages give detailed information on how and when to check your air pressure, how to inspect your tires for wear and damage, and our recommendations for tire repair and replacement.

Air Pressure

Refer to Safety Precautions on page 73.

Properly inflated tires provide the best combination of handling, tread life, and riding comfort. Generally, underinflated tires wear unevenly, adversely affect handling, and are more likely to fail from being overheated. Overinflated tires make your ATV ride harshly, are more prone to damage from surface hazards, and wear unevenly.

Make sure the air valve caps are secure. If necessary, install new caps.

Always check air pressure when your tires are “cold.” If you check air pressure when your tires are “warm” — even if your ATV has only been ridden for a few miles — the readings will be higher. If you let air out of warm tires to match the recommended cold tire pressures, the tires will be underinflated. Be sure to check tire pressure at the riding site, since changes in altitude can affect air pressure.

The recommended "cold" tire pressures are:

FRONT REAR
RECOMMENDED PRESSURE4.0 psi (27.5 kPa) 47 psi (32.5 kPa)

A manually operated tire pump should be used rather than the high pressure system found in service stations. This will minimize the possibility of tire damage from overinflation. If you use a high pressure system at a service station, add air in small amounts and check the pressure increase frequently to prevent possible tire damage from overinflation.

WARNING

Operating this ATV with improper tires, or with uneven tire pressure may cause loss of control, and you could be seriously injured or killed.

  • Always use the size and type tires specified in this owner's manual for this vehicle.
  • Always maintain proper tire pressure as described in this owner's manual.

Inspection

Refer to Safety Precautions on page 73.

Whenever you check the tire pressures, you should also look for:

  • Bumps or bulges in the side of the tire or the tread. Replace any tire that has a bump or bulge.
  • Cuts, slits, or cracks in the tires. Replace the tire if you can see fabric or cord.
  • Nails or other foreign objects embedded in the side of the tire or tread.
  • Excessive tread wear.

Also, if you hit a pothole or other hard object while riding, stop as soon as you safely can and carefully inspect the tires for damage.

To check the condition of a tire tread, measure the groove depth (1) in the center of the tire, or check the wear indicator (2).

For best performance, you should replace a tire before the tread depth at the center reaches the following limits:

front 3/16in (4 mm)
rear 3/16 in (4 mm)

Tire Repair

Refer to Safety Precautions on page 73.

A tire that is repaired, either temporarily or permanently, will have lower speed and performance limits than a new or undamaged tire.

A temporary repair can sometimes be made in an emergency situation. However, since a temporary repair may not hold, you must ride very slowly and have the tire replaced or permanently repaired as soon as possible. (For more information on temporary repairs, see If You Have a Flat Tire, page 181.)

A permanent repair, such as an internal plug patch, can be made if a tire has only a small puncture in the tread area. However you may not be able to safely carry as much weight. If you choose to have a tire repaired, be sure the repair work is performed by a professional.

If you have a tire professionally repaired at a non-Honda facility, we recommend that you have the work checked by your dealer.

Tire Replacement

Refer to Safety Precautions on page 73.

The tires that came on your ATV were designed to match the performance capabilities of your ATV and provide the best combination of handling, braking, and comfort.

It is best to replace all four tires, however if that is not possible, you must replace the tires in pairs (front or rear) with tires of the same size and type as the originals. Never replace just one tire.

WARNING

Installing improper tires on your ATV can affect handling and stability. This can cause a crash in which you can be seriously hurt or killed.

Always use the size and type of tires recommended in this owner's manual.

The recommended tires for your ATV are:

front AT21 × 7R10★★DUNLOP KT331H

rear AT20 × 10R9★★DUNLOP KT355H

When you replace a tire, remember:

Have the tire replaced by your dealer if possible.

If you have a tire professionally replaced at a non-Honda facility, we recommended that you have the work checked by your dealer.

Skid Plates & Engine Guard

Refer to Safety Precautions on page 73.

(1) (2)

(1) engine guard
(2) skid plates

The engine guard (1) protects the engine crankcase. The skid plates (2) protect the frame/lower arm, the drive components and the rear brake. Check the guard and plates for cracks, damage or looseness at intervals shown in the Maintenance Schedule.

Have the engine guard and skid plates replaced if they are cracked or damaged. If the guard and plate bolts are loose, tighten them securely.

An endless (riveted master link) chain connects the front and rear wheel sprockets. The O-ring chain uses rubber rings between the side plates of the pin and roller links to seal in the manufacturer-installed lubricating grease and keep out moisture and dirt.

The service life of the chain depends on proper lubrication and adjustment. Poor maintenance can cause premature wear or damage to the drive chain or sprockets.

The drive chain should be checked, adjusted, and lubricated as part of the pre-ride inspection (page 32).

Under severe usage, or when the ATV is ridden in unusually dusty or muddy areas, more frequent maintenance will be necessary.

Before servicing your drive chain, turn the engine OFF and check that your transmission is in neutral.

It is not necessary to remove or replace the drive chain to perform the recommended service in the Maintenance Schedule.

Inspection

Refer to Safety Precautions on page 73.

Your ATV has a maintenance-free type battery. You do not have to check the battery electrolyte level or add distilled water as you would with a conventional-type battery.

NOTICE

Your battery is a maintenance-free type and can be permanently damaged if the cap strip is removed.

Electrical accessories use current from the battery, even when the ignition is OFF. Limited operation also allows the battery to discharge.

If you have electrical accessories on your ATV or do not ride frequently, we recommend that you charge the battery frequently (see Battery Charging, page 158).

If you do not expect to ride your ATV for at least two weeks, we recommend you remove the battery, or at least disconnect the battery cables (negative cable first).

If you plan to store your ATV, see Battery Storage, page 155.

If your battery seems weak and/or is leaking electrolyte (causing slow starting or other electrical problems), see your dealer.

WARNING: Battery posts, terminals and related accessories contain lead and lead compounds. Wash your hands after handling.

Battery Storage

Refer to Safety Precautions on page 73.

If you plan to store your ATV, we recommend you remove the battery and store it where it can be charged at least every 30 days to maintain its service life.

If you do not remove the battery, we recommend disconnecting the battery cables (negative cable first).

You will get the best storage results from removing the battery and slow charging it every 30 days (see Battery Charging, page 158).

Before you remove the battery, be sure to read all the information that follows, as well as the information on the battery label.

WARNING

The battery gives off explosive hydrogen gas during normal operation.

A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you.

Wear protective clothing and a face shield, or have a skilled mechanic do the battery maintenance.

The battery is located in a compartment under the left rear fender.

Battery Charging

Refer to Safety Precautions on page 73.

(1)

(1) charger

Be sure to read the information that came with your battery charger and follow the instructions on the battery. Improper charging may damage the battery.

We recommend using a charger (1) designed specifically for your Honda, which can be purchased from your dealer. These units can be left connected for long periods without risking damage to the battery. However, do not intentionally leave the charger connected longer than the time period recommended in the charger's instructions.

Avoid using an automotive-type battery charger. An automotive charger can overheat an ATV battery and cause premature damage.

Frequent cleaning and polishing will keep your Honda looking newer longer.

Frequent cleaning also identifies you as an owner who values his ATV.

A clean ATV is also easier to inspect and service.

General Recommendations

Refer to Safety Precautions on page 73.

• To clean your ATV, you may use:

-water
- a mild, neutral detergent and water
- a mild spray and wipe cleaner/polisher
- a mild spray and rinse cleaner/ degreaser and water

- Avoid products that contain harsh detergents or chemical solvents that could damage the metal, paint, and plastic on your ATV.

  • If your ATV is still warm from recent operation, give the engine and exhaust system time to cool off.
  • Park in a shady area. Washing your ATV in bright sunlight may cause the finish to fade because water droplets intensify the sun's brightness.
  • Spotting is also more likely because surface water can dry before you have time to wipe it off.
  • Clean your ATV regularly to protect surface finishes.
  • We recommend the use of a garden hose to wash your ATV. High pressure washers (like those at coin-operated car washers) can damage certain parts of your ATV.

NOTICE

High pressure water (or air) can damage certain parts of your ATV.

- After cleaning, inspect for damage, wear, and leaks (fuel, oil, coolant and brake fluid).

Washing Your ATV with a Mild Detergent

Refer to Safety Precautions on page 73.

  1. Rinse your ATV thoroughly with cool water to remove loose dirt.
  2. Fill a bucket with cool water. Mix in a mild, neutral detergent, such as dish washing liquid or a product made especially for washing motorcycles or automobiles.
  3. Wash your ATV with a sponge or soft towel. As you wash, check for heavy grime. If necessary, use a mild cleaner/ degreaser to remove the grime.
  4. After washing, rinse your ATV thoroughly with plenty of clean water to remove any residue. Detergent residue can corrode alloy parts.
  5. Dry your ATV with a chamois or a soft towel. Leaving water on the surface to air dry can cause dulling and water spots. As you dry, inspect for chips and scratches.
  6. Start the engine and let it idle for several minutes. The engine heat will help dry moist areas.
  7. As a precaution, ride your ATV at a slow speed and apply the brakes several times. This will help dry the brakes and restore normal braking performance.
    If the inside of the headlight lens appears clouded immediately after washing, it should clear after a few minutes of riding.

Spray Cleaning Your ATV

Refer to Safety Precautions on page 73.

Avoid using spray cleaner products on the tires or suspension components.

Suggestions for using spray cleaner(s) follow:

ATV condition Recommended Cleaning
Dust and fingerprint smudges.Apply a spray cleaner/polish and wipe paint, chrome, glass, and clear plastic.
Light road grimes. Spray any difficult-to-reach or very dirty areas with a spray cleaner/degreaser.Rinse and dry.Apply a spray cleaner/polish and wipe with a non-abrasive cloth.
Heavy grime. Oil leaks. Brake dust.Use a spray cleaner/degreaser.If necessary, rub with a sponge.Rinse and dry.Apply a spray cleaner/polish and wipe with a non-abrasive cloth.
Dull, corroded chrome or aluminum.Apply a high quality chrome/aluminum polish and wipe with a non-abrasive cloth.

Aluminum Wheel Maintenance

Refer to Safety Precautions on page 73.

Aluminum may corrode from contact with dirt, mud, or road salt. Clean the wheels after riding through any of these substances. Use a wet sponge and mild detergent. Avoid stiff brushes, steel wool, or cleaners containing abrasives or chemical compounds.

After washing, rinse with plenty of water and dry with a clean cloth. Then apply a mild, commercially available spray cleaner/polish or wax.

For stained or dull-looking wheels, use a quality chrome/aluminum polish to restore the finish.

Finishing Touches

Refer to Safety Precautions on page 73.

After washing your ATV, consider using a commercially available spray cleaner/polish or quality liquid or paste wax to finish the job. Use only a non-abrasive polish or wax made specifically for motorcycles or automobiles. Apply the polish or wax according to the instructions on the container.

If a surface on your ATV is chipped or scratched, your dealer has touch-up paint to match your ATV's color. Be sure to use your ATV's color code (page 195) when you buy touch-up paint.

If the frame has a chip that exposes the metal, first apply primer (to prevent corrosion) and then apply the touch-up paint. Several thin layers of touch-up paint are better than one thick coat.

Exhaust Pipe and Muffler Maintenance

The exhaust pipe and muffler are stainless steel but may become stained by mud or dust.

To remove mud or dust, use a wet sponge and a liquid kitchen abrasive, then rinse well with clean water. Dry with chamois or a soft towel.

If necessary, remove heat stains by using a commercially available fine texture compound. Then rinse by the same manner as removing mud or dust.

You & the Environment 174

A safe and enjoyable ride begins with good planning and preparation. Always ride with at least one other person in case you have trouble, and let someone know where you're going and when you expect to return.

Before riding in an unfamiliar area, find out in advance if you need special permits, get maps so you can study the terrain, and talk to other riders who know the area. The Forest Service and the Bureau of Land Management (USA only), the Ministry of Natural Resources (Canada only), riding clubs, and off-road magazines are good sources of information.

What to Take to the Riding Area

Along with your ATV and riding gear, you should take along some tools and supplies in case you have a problem. For some of the difficulties you might encounter, see Taking Care of the Unexpected, which begins on page 175.

We recommend that you always take water, food, a first aid kit, and your owner's manual. Other items you should consider loading on your truck or trailer include:

  • a tool kit
  • tire repair supplies and tools, and tires
  • extra parts, control levers, cables, and spark plugs
  • wire, duct tape, and rope
  • extra gasoline

For safety, all refueling should be done at a gas station on the way to the riding area or at your base camp.

What to Take on the Trail

What you take with you during a ride depends on the kind of terrain, how long you expect to ride, how far you might go from your base camp or help, and how experienced you or your companions are in making repairs.

If you decide to take some tools, spare parts, or other supplies on the trail, be sure you can carry them safely and know how to use them. Also, be sure to follow the loading guidelines and weight limit (page 35).

Transporting Your Honda

Do not tow your ATV behind a car or other vehicle.

When you transport your ATV, we recommend that you carry the vehicle in its normal operating position (on all four wheels). Do not incline the vehicle upright on its rear end. This can damage the vehicle, and leaking gasoline could be a hazard.

Follow these procedures:

  1. Set the parking brake and place the transmission in gear.
  2. Turn the fuel valve OFF.

  3. Secure the vehicle with tie-down straps in the areas shown.

  4. Suitable tie-down straps are available from your dealer.

  5. Ordinary rope is not recommended because it can stretch under load.
  6. Using tie-down straps in any other areas can damage your ATV.

  7. Rock the vehicle back and forth to make sure the tie-down straps are tight and the vehicle is secure.

Storing Your Honda

If you won't be riding for an extended period, such as during the winter, thoroughly inspect your ATV and correct any problem before storing it. That way, needed repairs won't be forgotten and it will be easier to get your ATV running again.

For more information about storage, refer to the Honda Winter Storage Guide, available from your dealer (USA only).

We suggest you perform the following procedures to keep your ATV in top condition. These storage procedures will reduce the deterioration that can occur during storage.

Preparation for Storage

Refer to Safety Precautions on page 73.

This procedure requires a means for draining and disposing of drained fuel (page 174).

  1. Change the engine oil and filter (page 92).
  2. Change the transmission oil (page 98).
  3. Make sure the cooling system is filled with a 50/50% antifreeze solution (page 101).
  4. Fill the fuel tank. Make sure the fuel fill cap is properly installed.
  5. Check that the fuel valve is OFF.
  6. Drain the carburetor into an approved gasoline container and dispose of it in an approved manner (page 174).
    If storage will last longer than one month, carburetor draining is important to assure proper performance after storage.

WARNING

Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel.

  • Stop the engine and keep heat, sparks and flame away.
  • Handle fuel only outdoors.
  • Wipe up spills immediately.

  • To prevent rusting in the cylinder, perform the following:

  • Remove the spark plug cap from the spark plug.

  • Remove the spark plug.

Do not connect the spark plug to the spark plug cap.

(cont'd)

  • Pour a tablespoon (15 – 20 cc) of clean engine oil into the cylinder and cover the spark plug hole with a piece of cloth.
  • With the engine stop switch in the OFF (☒) position, press the start button several times to crank the engine and distribute the oil.
  • Reinstall the spark plug and spark plug cap.

  • Remove the battery and charge it fully. Store it in an area protected from freezing temperatures and direct sunlight. Slow charge the battery (page 158) once a month.

WARNING

The battery gives off explosive hydrogen gas during normal operation.

A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you.

Wear protective clothing and a face shield, or have a skilled mechanic do the battery maintenance.

  1. Wash and dry your ATV. Wax all painted surfaces.
  2. Lubricate the drive chain (page 152).

  3. Inflate the tires to their recommended pressures (page 140).

  4. Store your ATV in an unheated area, free of dampness, away from sunlight, with a minimum of daily temperature variation.
  5. Place your ATV on blocks to lift all tires off the floor.
  6. Cover your ATV with a porous material. Avoid using plastic or similar non-breathing, coated materials that restrict air flow and allow heat and moisture to accumulate.

Removal from Storage

Refer to Safety Precautions on page 73.

  1. Uncover and clean your ATV.
  2. If your ATV has been stored for more than four months — change the engine oil (page 92) and transmission oil (page 98).
    Add coolant to the reserve tank as required to bring the coolant level to the UPPER level mark.
  3. If your ATV has been stored for more than two months — ask your dealer to drain and replace the fuel.
  4. Lubricate the drive chain (page 152).
  5. Charge the battery (page 158) as required. Install the battery.
  6. Perform a pre-ride inspection (page 31), then test-ride your ATV at low speeds.

Owning and riding an ATV can be enjoyable, but you must do your part to protect nature. When you show respect for the land, wildlife, and other people, you also help preserve the sport of off-road riding.

Following are tips on how you can be an environmentally responsible ATV owner.

  • Tread Lightly. Stay on existing roads and trails, avoid surfaces that are easily damaged, and ride only in areas approved for off-road vehicles.
  • Keep the Noise Down. Loud vehicles can be offensive. Ride as quietly as possible, don’t remove your spark arrester, and don’t modify the muffler or any other part of your air intake and exhaust systems. Such modifications not only increase noise, they also reduce engine performance and may be illegal.
  • Choose Sensible Cleaners. Use a biodegradable detergent when you wash your ATV. Avoid aerosol spray cleaners that contain chlorofluorocarbons (CFCs) which damage the atmosphere's protective ozone layer. Don't throw cleaning solvents away; see the following guidelines for proper disposal.
  • Recycle Wastes. It’s illegal and thoughtless to put used engine oil in the trash, down a drain, or on the ground. Used oil, gasoline, and cleaning solvents contain poisons that can hurt refuse workers and contaminate our drinking water, lakes, rivers, and oceans. Before changing your oil, make sure you have the proper containers. Put oil and other toxic wastes in separate sealed containers and take them to a recycling center. Call your local or state office of public works or environmental services to find a recycling center in your area, and to get instructions on how to dispose of non-recyclable wastes.

Taking Care of the Unexpected

With all the challenges you can encounter off-road, there's a chance that sometime something may go wrong. This section gives practical advice to help you deal with a wide range of problems. Take time to read this section before you ride. Also review the tips in Preparing for a Ride (page 166).

General Guidelines

Keeping your ATV well-maintained is the best way to reduce the possibility of having a problem while riding. However, problems can arise even with well-maintained machines.

Remember to take along your owner's manual, the tool kit that came with your ATV, and any other items (such as tire repair supplies and additional tools) that might help you solve a problem on your own.

If something goes wrong during a ride, the first thing to do is stop as soon as you safely can. Do not continue riding if you have a flat tire, or you hear an unusual noise, or your ATV just doesn't feel right. If you continue riding, you could cause more damage and endanger your own safety.

After stopping, take time to assess the situation. Carefully inspect your ATV to identify the problem, then consider your options before you decide what to do.

If a problem is relatively minor and you have the tools, supplies, and skills to make a permanent repair, you may be able to fix it on the trail and continue riding. Or, you may be able to make a temporary repair that allows you to slowly ride back to your base where you can make a permanent repair or get help.

When a problem is more serious — or you don’t have the tools, supplies, experience, or time to deal with it — you need to choose the safest way to get yourself and your ATV back to base. For example, if you are close enough, you (or you and another person) might be able to push it back.

Should you ever have a problem while riding, please follow these guidelines:

• Always put personal safety first.
- Take time to assess the situation and your options before deciding what to do.
- If the problem is relatively minor and you have the tools, supplies, and skills to make a temporary repair, be sure to have permanent repairs made as soon as possible.
- Do not continue riding if you are hurt or your ATV is not in safe riding condition.

Additional recommendations for specific problems follow.

If Your Engine Quits or Won't Start

Proper operation and maintenance can prevent starting and engine performance problems. In many cases, the cause of the problem may be a simple operational oversight.

If you have a problem starting the engine — or experience poor engine performance — the following information may help you. If you can't correct the problem, see your dealer.

If your ATV won't start, listen as you press the start button. If you don't hear the starter motor turning, refer to the Starter motor doesn't operate symptom. If you can hear the starter motor working normally, refer to the Starter motor works, but the engine won't start symptom.

If Your Engine Quits or Won't Start

SYMPTOM: Starter motor doesn’t operate.
POSSIBLE CAUSE WHAT TO DO
ignition switch OFF Turn the ignition switch ON.
transmission not in neutralShift into neutral.
blown fuse Replace with a new fuse of the same rating (page 187).
battery lead loose Tighten the battery lead.
low (or dead) battery Charge the battery (page 158).If charging doesn’t help, see your dealer.
faulty starter motor If all possible causes are negative, the starter motor may be faulty. See your dealer.
SYMPTOM: Starter motor works, but the engine won’t start.
POSSIBLE CAUSE WHAT TO DO
engine stop switch OFF Turn the engine stop switch to RUN.
out of fuel Fill the fuel tank.
flooded engineSee Flooded Engine (page 50).
loose or unconnected spark plug capInstall the spark plug cap securely. If the engine still won’t start, see your dealer.
not enough throttle freeplayCheck the throttle freeplay (page 110).
loose battery cables Tighten the battery terminal bolts.
weak battery Charge the battery (page 158).If charging doesn’t help, see your dealer.

If Your Engine Quits or Won't Start

SYMPTOM: Engine starts, but runs poorly.
POSSIBLE CAUSE WHAT TO DO
idles roughly, too fast, stallsCheck engine idle adjustment (page 116). If the problem persists, see your dealer.
improperly throttle freeplayCheck the throttle freeplay (page 110).
poor engine performance at altitudes above 4,500 feet (1,500 m).Ask your dealer to modify the carburetion with a high altitude jet. Refer to High Altitude Carburetor Adjustment, page 202.
high coolant temperatureCheck the high coolant temperature indicator. Refer to If the High Coolant Temperature Indicator Lights, page 185.
runs erratically, misfires See your dealer.
blubbers (rich fuel mixture)See your dealer.
sooty exhaust (rich fuel mixture)See your dealer.
detonates or pings under loadIf applicable, switch to the recommended octane gasoline (page 85) or change your brand of gasoline. If the problem persists, see your dealer.
afterfires (backfires) See your dealer.
pre-ignition (runs on after ignition switched OFF)See your dealer.

How you handle a flat tire on the trail depends on how serious the tire damage is, and what tools and supplies you have with you.

If you have a slow leak or a minor puncture, use the plug method to make a temporary repair. (The plug method is applied from the outside of the tire and is the same as that for conventional tubeless tires.)

A plug-type repair kit, available at most auto parts stores or service stations, provides a plug, an installation tool, tire cement, and an instruction sheet. Follow the instructions provided with the repair kit to make a temporary repair.

As soon as possible, have the tire permanently repaired by your dealer. Any tire that cannot be repaired should be replaced.

Whenever the ATV is to be operated far from service facilities or available transportation, we recommend that you carry a tire pump and a repair kit with the vehicle.

If the leak is more serious, or a temporary repair doesn't hold, the tire must be replaced. The tire will also need to be replaced if it is damaged (page 145). Replacing a tire involves removing and re-installing the wheel (page 183).

If you are unable to repair a flat tire on the trail, you will need to send for help. We strongly recommend that you do not try to ride with a flat tire. The ATV will be hard to handle, and if the tire comes off the rim, it may lock up the wheel and cause you to crash.

WARNING

Riding your ATV with a temporary tire repair can be risky.

If the temporary repair fails, you can crash and be seriously injured or killed. If you must ride with a temporary tire repair, ride slowly and carefully until the tire is permanently repaired or replaced.

Emergency Wheel Removal/Installation

Refer to Safety Precautions on page 73.

Honda TRX450R (2013) - Emergency Wheel Removal/Installation - 1
(1) wheel nuts (2) wheel rim

Removal

  1. Park your ATV on a firm, level surface.
  2. Loosen — but do not remove — the wheel nuts (1).
  3. Raise the front (or rear) wheels off the ground and place a support block under the vehicle.
  4. Remove the wheel nuts.
  5. Remove the wheel.

- Avoid getting grease, oil, or dirt on the disc or pad surfaces when removing and installing each wheel. Any contamination can cause poor brake performance or rapid pad wear after reassembly.

Installation

  1. Position the wheel.
  2. Position the wheel nuts so that the tapered sides face the wheel rim (2).
  3. Hand-tighten the wheel nuts on the wheel, then lower the ATV to the ground before tightening the nuts in a crisscross (rather than circular) pattern to the specified torque:

47 lbf·ft (64 N·m, 6.5 kgf·m)

If a torque wrench was not used for installation, see your dealer as soon as possible to verify proper assembly. Improper assembly may lead to loss of braking capability.

Normally, the high coolant temperature indicator will only light momentarily when you turn the ignition ON (1). Occasionally, it may flicker at or near idling speed.

High coolant temperature may be caused by restriction of air flow to the radiator (such as mud caked on the radiator), extended idling, an oil leak, a coolant leak, a low oil level, a low coolant level, or extended operation under adverse conditions.

If the indicator comes on while you're riding, don't ignore it. Pull safely to a stop. Stop the engine as soon as it's safe to do so, and let it cool.

NOTICE

Continuing to ride with high coolant temperature or an overheated engine can cause serious engine damage.

  • A steaming engine indicates a coolant leak. Shut the engine off and wait until the steaming stops. Look for a leak, but don't touch the engine or radiator system. Let everything cool off first.
  • Check for any restriction of air flow through the radiator.
  • If there's no obvious problem, leave the engine on so the fan and coolant circulating system can continue working. Monitor the high coolant temperature indicator. The indicator may turn off after a brief stop with no load on the engine.
  • Check the radiator fan. If the fan is not working, have your dealer check for problems. If the radiator fan is working, visually check the coolant level in the reserve tank, located under the steering cover. It isn't necessary to touch the radiator system.

If the High Coolant Temperature Indicator Lights

- If the reserve tank is low or empty, don't ride without adding coolant (page 101). After adding coolant, turn the engine on and check the high coolant temperature indicator.

If the indicator doesn't turn off, do not ride. The engine needs repair.

Transport your ATV to your dealer (page 168).

If the temperature drops to normal, check the coolant level. If it has gone down, add more coolant.

- Check for an oil leak.

- Check the oil level. If necessary, add the recommended oil (page 91) to the upper level mark. If you must leave your ATV to get oil, secure it as much as possible.

- Start the engine, and check that the high coolant temperature indicator goes off.

If the indicator goes off — resume riding. If there is a leak — do not ride the ATV until the leak is repaired by your dealer.

If there's a mild coolant leak, you can ride for awhile, carefully watching the indicator. Be prepared to stop and add more coolant or water. If the leak is bad, transport your ATV to your dealer (page 168).

All of the electrical circuits on your ATV have a fuse to protect them from damage caused by excess current flow (short circuit or overload).

If something electrical on your ATV stops working, the first thing you should check for is a blown fuse (1).

Check the fuse before looking elsewhere for another possible cause of the problem. Replace a blown fuse and check component operation.

  1. To prevent an accidental short circuit, turn the ignition switch OFF (O) before checking or replacing the fuse.
  2. To access the main fuse (1), remove the battery cover (page 156).
  3. Remove the fuse case cover (2).
  4. Pull the main fuse out.
    If it is blown, install the spare main fuse (3).

If you do not have a replacement fuse with the proper rating for the circuit, install one with a lower rating.

NOTICE

Replacing a fuse with one that has a higher rating greatly increases the chance of damage to the electrical system.

  1. Reinstall the fuse case cover.
  2. Install the battery cover.

If the replacement fuse of the same rating burns out in a short time, there is probably a serious electrical problem on your ATV. Leave the blown fuse in that circuit and have your ATV checked by your dealer.

Personal safety is your first priority after a crash. If you or anyone else has been injured, take time to assess the severity of the injuries and whether it is safe to continue riding. If you cannot ride safely, send someone for help. Do not ride if you will risk further injury.

If you decide you are capable of riding safely, carefully inspect your ATV for damage and determine if it is safe to ride. Check the tightness of critical nuts and bolts securing such parts as the handlebar, control levers, brakes, and wheels.

If there is minor damage, or you are unsure about possible damage but decide to try riding the ATV back to your base, ride slowly and cautiously.

Sometimes, crash damage is hidden or not immediately apparent. When you get home, thoroughly check your ATV and correct any problems you find. Also, be sure to have your dealer check the frame and suspension after any serious crash.

If You Lose Your Key

Be sure to record your key number (1). Store the spare key and recorded key number in a safe location. You'll need this number to have a duplicate key made.

If you lose your key and aren't carrying a duplicate, either get your spare or have one made. If you don't know your key number, call the dealer where you purchased your Honda ATV. They may have it listed in their records. If they don't, transport your ATV to them or the nearest dealer. The dealer will probably have to remove the ignition switch assembly to find the key number so they can make a key for you.

If the Battery Is Low (or Dead)

Jump starting is not recommended, especially if you use an automobile battery. The greater amperage of an automobile battery when the car engine is running can damage your ATV's electrical system.

Bump starting is also not recommended.

If you can't charge the battery or it appears unable to hold a charge, contact your dealer.

The levers or pedal, control cables, and other components can be damaged as you ride in dense brush or over rocky terrain. Making a trailside repair depends on how serious the damage is and what tools and supplies you have with you.

  • If any component of the brake system is damaged, you may be able to ride carefully back to your base using the other brake components for slowing or stopping.
  • If you damage a throttle cable or other critical component, your ATV may be unsafe to ride. Carefully assess the damage and make any repairs that you can. But if there is any doubt, it's best to be conservative and safe.

High Altitude Carburetor Adjustment

At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 6,500 feet (2,000 meters), have your servicing dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life.

Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

NOTICE

When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may cause the engine to overheat and result in serious engine damage. For use at low altitudes, have your servicing dealer return the carburetor to original factory specifications.

Exhaust Emission Requirements

The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Environment Canada (EC) require that your ATV comply with applicable exhaust emissions standards during its useful life, when operated and maintained according to the instructions provided.

The Vehicle Emission Control Information Label (1) (2) is attached on the front of the frame.

Emission Control Systems

Source of Exhaust Emissions

The combustion process produces carbon monoxide (CO), oxides of nitrogen (NOx) and hydrocarbons (HC). Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.

Honda Motor Co., Ltd. utilizes various systems to reduce carbon monoxide, oxides of nitrogen and hydrocarbons.

Exhaust Emission Control System

The exhaust emission control system is composed of appropriate carburetor settings. No adjustments should be made except for an idle speed adjustment with the throttle stop screw or carburetor adjustment for high altitude operation.

The exhaust emission control system is separate from the crankcase emission control system.

Crankcase Emission Control System

The engine is equipped with a closed crankcase system to prevent discharging crankcase emissions into the atmosphere. Blow-by gas is returned to the combustion chamber through the air cleaner and the carburetor.

Problems That May Affect ATV Exhaust Emissions

If you are aware of any of the following symptoms, have the vehicle inspected and repaired by your ATV dealer.

Symptoms:

  1. Hard starting or stalling after starting
  2. Rough idle
  3. Misfiring or backfiring during acceleration
  4. After-burning (backfiring)
  5. Poor performance (driveability) and poor fuel economy

Federal regulations prohibit removing or disabling a device or element of design that may affect your engine's emission performance unless your ATV will be used exclusively in competition. If you modify your engine for use in sanctioned competition events, you must deface or destroy the emission control information label.

Noise Emission Control System

TAMPERING WITH THE NOISE CONTROL SYSTEM IS PROHIBITED: State laws prohibit, or Canadian provincial laws may prohibit, the following acts or the causing thereof: (1) The removal or rendering inoperative by any person, other than for purposes of maintenance, repair or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use; or (2) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person.

AMONG THOSE ACTS PRESUMED TO CONSTITUTE TAMPERING ARE THE FOLLOWING ACTS:

  1. Removal of, or puncturing the muffler, baffles, header pipes or any other component which conducts exhaust gases.
  2. Removal of, or puncturing of any part of the intake system.
  3. Lack of proper maintenance.
  4. Replacing any moving parts of the vehicle, or parts of the exhaust or intake system, with parts other than those specified by the manufacturer.

Fuel Permeation Emission Control System

This vehicle complies with the Fuel Permeation Emission Control regulations of the U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Environment Canada (EC).

The fuel tank, fuel hoses, and fuel vapor charge hoses used on this vehicle incorporate fuel permeation control technologies.

Tampering with the fuel tank, fuel hoses, or fuel vapor charge hoses to reduce or defeat the effectiveness of the fuel permeation technologies is prohibited by federal regulations.

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel's contents. Some states/provinces require this information to be posted on the pump.

The following are the EPA-approved percentages of oxygenates for non road vehicles:

ETHANOL (ethyl or grain alcohol) 10% by volume You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name "Gasohol".

Do not use gasoline containing more than 10% ethanol by volume. The use of gasoline containing a higher percentage (e.g. E15, E20, E85) of ethanol has not been approved for use in this vehicle and may cause starting and/or performance problems and can also damage metal, rubber, and plastic parts of the fuel system and are not be covered by the Distributor's Limited Warranty.

MTBE (Methyl Tertiary Butyl Ether) 15% by Volume You may use gasoline containing up to 15% MTBE by volume.

METHANOL (methyl or wood alcohol) 5% by Volume You may use gasoline containing methanol containing up to 5% methanol by volume as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of your fuel system.

If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.

Oxygenated fuels can damage paint and plastic. Be careful not to spill fuel when filling the fuel tank. Wipe up any spills immediately.

NOTICE

Oxygenated fuels can damage paint and plastic. Damage caused by spilled fuel is not covered by warranty.

The following is a brief, but important collection of information you need to know about your Honda. You'll also find space to record important notes.

How To Avoid Costly Repairs

The engine of your Honda can be the most expensive component to repair. Proper maintenance, especially the use of the recommended fluids and filters, prevents premature wear and damage.

Frequent causes of costly repairs are:

  • Engine oil — insufficient quantity, improper oil.
  • Air cleaner — dirty, leaking because of improper installation (poor seal).
