Use definition (XCF-W, XC-F, SX-F)

KTM sport motorcycles are designed and built to withstand the normal stresses and strains of competitive use. The motorcycles comply with currently valid regulations and categories of the top international motorsport organizations.

Info

The motorcycle is designed for off-road sport endurance competition (Enduro) and not for the predominant motocross use.

Maintenance

A prerequisite for perfect operation and prevention of wear is that the engine and chassis maintenance and adjustment work described in the owner's manual are properly carried out. Poor adjustment and tuning of the engine and chassis can lead to damage and breakage of components.

Using the motorcycle in extreme conditions such as very muddy or wet terrain can lead to above-average wear of components such as the transmission train or the brakes. For this reason, it may be necessary to service or replace worn parts before the limit specified in the service schedule is reached.

Pay careful attention to the prescribed running-in period, inspection and maintenance intervals. If you observe these exactly, you will ensure a much longer service life for your motorcycle.

Warranty

The work prescribed in the service schedule must be carried out in an authorized KTM workshop and confirmed in the customer's service record, since otherwise no warranty claims will be recognized. No warranty claims can be considered for damage resulting from manipulations and/or alterations to the vehicle.

Fuel, oils, etc.

You should use the fuels, oils and greases according to specifications as listed in the owner's manual.

Spare parts, accessories

For your own safety, only use spare parts and accessory products that are approved and/or recommended by KTM and have them installed by an authorized KTM workshop. KTM accepts no liability for other products and any resulting damage or loss.

The current KTM PowerParts for your vehicle can be found on the KTM website.

International KTM Website: http://www.ktm.com

Work rules

When the vehicle is assembled, non-reusable parts (e.g., self-locking screws and nuts, gaskets, seal rings, O-rings, splints, lock washers) must be replaced with new parts.

Where thread lockers are used on screw connections (e.g., Loctite®), follow the instructions for use from the manufacturer.

After disassembly, clean the parts that are to be reused and check them for damage and wear. Replace damaged or worn parts.

After you complete the repair or maintenance work, check the roadworthiness of the vehicle.

Starting

Danger

Danger of poisoning Exhaust gases are poisonous and can result in unconsciousness and/or death.

• When running the engine, always make sure there is sufficient ventilation, and do not start or run the engine in a closed space.

Note

Engine failure High engine speeds in cold engines have a negative effect on the service life of the engine.

Always warm up the engine at low engine speeds.

Info

If the motorcycle is unwilling to start, the cause can be old fuel in the float chamber. The flammable elements of the fuel evaporate after a long time of standing.

If the float chamber is filled with fresh fuel, the engine starts immediately.

Press the starter for a maximum of 5 seconds. Wait for a least 5 seconds until trying again.

Engine has been out of use for more than 1 week

Empty the carburetor float chamber. (p. 85)

(EXC-F, EXC-F SIX DAYS, XCF-W, XC-F)

• Turn handle ① of the fuel tap to the ON position. (Figure 500137-10 p. 22)

Fuel can flow from the fuel tank to the carburetor.

(SX-F)

(EXC-F EU, EXC-F SIX DAYS)

Pull the choke lever to the stop.

• Press the electric starter button or press the kickstarter robustly through its full range.

Info

Don't open the throttle.

Starting up

Info

If your bike has lights, switch them on before riding. You will then be seen earlier by other motorists.

When you are riding, the side stand must be folded up and secured with the rubber band.

Pull the clutch lever, engage 1st gear, release the clutch lever slowly and simultaneously open the throttle carefully.

Shifting, riding

Warning

Danger of accidents If you change down at high engine speed, the rear wheel can lock up.

• Do not change into a low gear at high engine speed. The engine races and the rear wheel can block.

Info

If you hear unusual noises while riding, stop immediately, switch off the engine and contact an authorized KTM workshop.

First gear is used for starting off or for steep inclines.

• When conditions allow (incline, road situation, etc.), you can shift into a higher gear. To do so, release the throttle while simultaneously pulling the clutch lever, shift into the next gear, release the clutch and open the throttle.
• If the choke function was activated, deactivate it after the engine has warmed up.
• When you reach maximum speed after fully opening the throttle, turn back the throttle to about 34 of its range; the speed hardly drops, but the fuel consumption falls considerably.
  Always open the throttle only as much as the engine can handle – abrupt throttle opening increases fuel consumption.
• To shift down, brake and close the throttle at the same time.
  Pull the clutch lever and shift into a lower gear, release the clutch lever slowly and open the throttle or shift again.
• Switch off the engine if you expect to be standing for a long time.

Guideline

≥ 2 min

• Avoid frequent and longer slipping of the clutch. This heats the engine oil, the engine and the cooling system.
• Ride with a lower engine speed instead of with a high engine speed and a slipping clutch.

Braking

Warning

Danger of accidents If you brake too hard, the wheels can lock.

• Adapt your braking to the traffic situation and the road conditions.

Warning

Danger of accidents Reduced braking caused by spongy pressure point of front or rear brake.

• Have the brake system checked in an authorized KTM workshop, and do not ride any further.

Warning

Danger of accidents Reduced braking due to wet or dirty brakes.

• Clean or dry dirty or wet brakes by riding and braking gently.

• On sandy, wet or slippery surfaces, use the rear brake.

• Braking should always be completed before you go into a bend. Change down to a lower gear appropriate to your road speed.
• On long downhill stretches, use the braking effect of the engine. Change down one or two gears, but do not overpress the engine. In this way, you have to brake far less and the brakes do not overheat.

Stopping, parking

Warning

Risk of misappropriation Usage by unauthorized persons.

• Never leave the vehicle while the engine is running. Secure the vehicle against use by unauthorized persons.

Warning

Danger of burns Some vehicle components get very hot when the machine is driven.

Refueling

Danger

Fire hazard Fuel can easily catch fire.

• Never fill up the vehicle near open flames or burning cigarettes, and always switch off the engine first. Be careful that no fuel is spilt, especially on hot vehicle components. Clean up spilt fuel immediately.
  Fuel in the fuel tank expands when warm and can escape if the tank is overfilled. See specifications on filling up with fuel.

Warning

Danger of poisoning Fuel is poisonous and a health hazard.

• Avoid contact between fuel and skin, eyes and clothing. Do not inhale fuel vapors. If fuel gets into your eyes, rinse immediately with water and contact a doctor. Wash affected skin areas immediately with soap and water. If fuel is swallowed, contact a doctor immediately. Change clothing that has come into contact with fuel.

Warning

Environmental hazard Improper handling of fuel is a danger to the environment.

• Do not allow fuel to get into the ground water, the ground, or the sewage system.

• Switch off the engine.

• Open the filler cap. (p. 22)

• Fill the fuel tank with fuel up to measurement A.

Guideline

Measurement of A		35 mm (1.38 in)
Total fuel tank capacity, approx. (EXC-F, EXC-F SIX DAYS, XCF-W, XC-F)	9.2 l (2.43 US gal)	Super unleaded (ROZ 95 / RON 95 / PON 91) (p. 116)

Checking the basic chassis setting with the rider's weight

Info

When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

• For optimal motorcycle riding characteristics and to avoid damage to forks, shock absorbers, swing arm and frame, the basic settings of the suspension components must match your body weight.
• As delivered, KTM offroad motorcycles are adjusted for a standard rider weight (with full protective clothing). Guideline

Standard rider weight

75... 85 kg (165... 187 lb.)

If your weight is above or below the standard range, you have to adjust the basic setting of the suspension components accordingly.
- Small weight differences can be compensated by adjusting the spring preload, but in the case of large weight differences, the springs must be replaced.

Compression damping of shock absorber

The shock absorber can regulate compression damping separately in the low-speed and high-speed ranges (Dual Compression Control). The term low and high speed refers to the movement of the shock absorber during compression and not the riding speed of the motor-cycle.

The low-speed and high-speed technology works non-specifically.

Adjusting high-speed compression damping of the shock absorber

Danger

Danger of accidents The shock absorber is under high pressure.

The shock absorber is filled with highly compressed nitrogen, so never dismantle the shock absorber or carry out any maintenance on it yourself.

Cleaning motorcycle

Note

Material damage Damage and destruction of components by high-pressure cleaning equipment.

• Never clean the vehicle with high-pressure cleaning equipment or a strong water-jet. The excessive pressure can penetrate electrical components, connects, Bowden cables, and bearings, etc., and can damage or destroy these parts.

Warning

Environmental hazard Problem materials cause environmental damage.

• Dispos of oil, grease, filters, fuel, cleaning substances, brake fluid, batteries, etc. according to regulations.

Info

If you clean the motorcycle regularly, its value and appearance are maintained over a long period.

Avoid direct sunshine on the motorcycle during cleaning.

Before you clean the motorcycle, seal the exhaust system to prevent penetration by water.
- First remove coarse dirt particles with a gentle water spray.
Spray very dirty areas with a normal motorcycle cleaner and then clean with a paintbrush.

Motorcycle cleaner (p. 117)

Info

Use warm water containing normal motorcycle cleaner and a soft sponge.

• After rinsing the motorcycle with a gentle water spray, allow it to dry thoroughly.
  Empty the carburetor float chamber. (p. 85)

Warning

Danger of accidents Reduced braking due to wet or dirty brakes.

• Clean or dry dirty or wet brakes by riding and braking gently.

After cleaning, ride the vehicle a short distance until the engine warms up, and then apply the brakes.

Info

The heat produced causes water at inaccessible positions in the engine and the brakes to evaporate.

• Push back the protection covers on the handlebar instruments to allow water to evaporate.
• After the motorcycle has cooled off, oil or grease all moving parts and bearings.
  Clean the chain. (p. 57)
  Treat bare metal parts (except for brake discs and exhaust system) with anti-corrosion materials.

Cleaning and polishing materials for metal, rubber and plastic (p. 117)

Treat all painted parts with a mild paint polish.

High-luster polish for paint (p. 117)

• To prevent electrical problems, treat electric contacts and switches with contact spray.

Contact spray (p. 117)

(EXC-F, EXC-F SIX DAYS)

Lubricate the steering lock.

Universal oil spray (p. 118)

Storage

Warning

Danger of poisoning Fuel is poisonous and a health hazard.

• Avoid contact between fuel and skin, eyes and clothing. Do not inhale fuel vapors. If fuel gets into your eyes, rinse immediately with water and contact a doctor. Wash affected skin areas immediately with soap and water. If fuel is swallowed, contact a doctor immediately. Change clothing that has come into contact with fuel. Store fuel in a suitable canister according to regulations and keep it out of the reach of children.

Info

If you want to garage the motorcycle for a longer period, take the following actions.

Before storing the motorcycle, check all parts for function and wear. If service, repairs or replacements are necessary, you should do this during the storage period (less workshop overload). In this way, you can avoid long workshop waiting times at the start of the new season.

Clean the motorcycle. (p. 92)
- Change the engine oil and oil filter, clean the oil screen. (p. 86)
- Check the antifreeze and coolant level. (p. 80)
- Drain the fuel from the tank into a suitable container.
Empty the carburetor float chamber. (p. 85)
- Check the tire air pressure. (p. 75)

(EXC-F, EXC-F SIX DAYS, XCF-W, XC-F)

• Remove the battery. (p. 75)

(EXC-F, EXC-F SIX DAYS, XCF-W, XC-F)

• Recharge the battery. (p. 76)

Guideline

Storage temperature of battery without direct sunlight. 0...35°C (32...95°F)

• The storage place should be dry and not subject to large temperature fluctuations.

Info

KTM recommends jacking up the motorcycle.

• Jack up the motorcycle. (p. 37)
  Cover the motorcycle with a porous sheet or blanket. Do not use non-porous materials since they prevent humidity from escaping, thus causing corrosion.

Info

Avoid running the engine for a short time only. Since the engine cannot warm up properly, the water vapor produced during combustion condenses and causes valves and exhaust system to rust.

Putting into operation after storage

• Remove the motorcycle from the work stand. (p. 37)

(EXC-F, EXC-F SIX DAYS, XCF-W, XC-F)

Install the battery. (p. 76)

• Fill up with fuel. (p. 30)
• Checks before putting into operation (p. 28)

JASO T903 MA

Different technical development directions required a new specification for 4-stroke motorcycles – the JASO T903 MA Standard. Earlier, engine oils from the automobile industry were used for 4-stroke motorcycles because there was no separate motorcycle specification. Whereas long service intervals are demanded for automobile engines, high performance at high engine speeds are in the foreground for motorcycle and ATV engines. With most motorcycles and ATVs, the gearbox and the clutch are lubricated with the same oil as the engine. The JASO MA Standard meets these special requirements.

SAE

The SAE viscosity classes were defined by the Society of Automotive Engineers and are used for classifying oils according to their viscosity. The viscosity describes only one property of oil and says nothing about quality.
