A Few Words About Safety

Your safety, and the safety of others, is very important. Operating this scooter safely is an important responsibility.

To help you make informed decisions about safety, we have provided operating procedures and other information on safety labels and in this manual. This information alerts you to potential hazards that could hurt you or others.

Of course, it is not practical or possible to warn you about all hazards associated with operating or maintaining a scooter. You must use your own good judgment.

You will find important safety information in a variety of forms, including:

● Safety labels on the scooter
● Safety Messages preceded by a safety alert symbol and one of three signal words:
DANGER, WARNING, or CAUTION.
These signal words mean:

DANGER

You WILL be KILLED or SERIOUSLY HURT if you don't follow instructions.

WARNING

You CAN be KILLED or SERIOUSLY HURT if you don't follow instructions.

CAUTION

You CAN be HURT if you don't follow instructions.

Other important information is provided under the following titles:

NOTICE

Information to help you avoid damage to your scooter, other property, or the environment.

Safety Guidelines

Follow these guidelines to enhance your safety:

● Perform all routine and regular inspections specified in this manual.
- Stop the engine and keep sparks and flame away before filling the fuel tank.
- Do not run the engine in enclosed or partly enclosed areas. Carbon monoxide in exhaust gases is toxic and can kill you.

Always Wear a Helmet

It's a proven fact: helmets and protective apparel significantly reduce the number and severity of head and other injuries. So always wear an approved motorcycle helmet and protective apparel. ➡ P. 9

Before Riding

Make sure that you are physically fit, mentally focused and free of alcohol and drugs. Check that you are wearing an approved scooter helmet and protective apparel.

Take Time to Learn & Practice

Even if you have ridden other scooters, practice riding in a safe area to become familiar with how this scooter works and handles, and to become accustomed to the scooter's size and weight.

Safety Guidelines

We recommend that all riders take a certified course approved by the Motorcycle Safety Foundation (MSF). New riders should start with the basic course, and even experienced riders will find the advanced course beneficial. For information about the MSF training course nearest you, call the national toll-free number: (800) 446-9227.

Other riding tips can be found in the You and Your Motorcycle Riding Tips booklet that came with your scooter.

Ride Defensively

Always pay attention to other vehicles around you, and do not assume that other drivers see you. Be prepared to stop quickly or perform an evasive maneuver.

Make Yourself Easy to See

Make yourself more visible, especially at night, by wearing bright reflective clothing, positioning yourself so other drivers can see you, signaling before turning or changing lanes, and using your horn when necessary.

Ride within Your Limits

Never ride beyond your personal abilities or faster than conditions warrant. Fatigue and inattention can impair your ability to use good judgment and ride safely.

Don't Drink and Ride

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

Safety Guidelines

Keep Your Honda in Safe Condition

It's important to keep your scooter properly maintained and in safe riding condition. Inspect your scooter before every ride and perform all recommended maintenance. Never exceed load limits (P. 14), and do not modify your scooter or install accessories that would make your scooter unsafe (P. 13).

If You are Involved in a Crash

Personal safety is your first priority. 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. Call for emergency assistance if needed. Also follow applicable laws and regulations if another person or vehicle is involved in the crash.

If you decide to continue riding, first turn the ignition switch to the OFF position, and evaluate the condition of your scooter. Inspect for fluid

leaks, check the tightness of critical nuts and bolts, and check the handlebar, control levers, brakes, and wheels. Ride slowly and cautiously. Your scooter may have suffered damage that is not immediately apparent. Have your scooter thoroughly checked at a qualified service facility as soon as possible.

Safety Guidelines

Carbon Monoxide Hazard

Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing carbon monoxide can cause loss of consciousness and may lead to death.

If you run the engine in confined or even partly enclosed area, the air you breathe could contain a dangerous amount of carbon monoxide.

Never run your scooter inside a garage or other enclosure.

WARNING

Running the engine of your scooter while in an enclosed or even partially enclosed area can cause a rapid build-up of toxic carbon monoxide gas.

Breathing this colorless, odorless gas can quickly cause unconsciousness and lead to death.

Only run your scooter's engine when it is located in a well ventilated area outdoors.

Safety Labels

Safety Labels

Safety and information labels on your scooter provide important safety information and may warn you of potential hazards that could cause

serious injury. Read these labels carefully and don't remove them. If a label comes off or becomes hard to read, contact your dealer for a replacement.

WARNING Improper loading can cause a crash and you may be seriously hurt or killed. See "Load Limits and Guidelines" in your Owner's Manual for complete instructions.

Riding Precautions

Riding Precautions

Break-in Period

During the first 60 miles (100 km) of running, follow these guidelines to ensure your scooter's future reliability and performance.

  • Avoid full-throttle starts and rapid acceleration.
  • Avoid hard braking.
  • Ride conservatively.

Brakes

Observe the following guidelines:

● Avoid excessively hard braking.

▶ Sudden braking can reduce the scooter's stability.
▶ Where possible, reduce speed before turning; otherwise you risk sliding out.

● Exercise caution on low traction surfaces.
The tires slip more easily on such surfaces and braking distances are longer.
● Avoid continuous braking.
▶ Repeated braking, such as when descending long, steep slopes can seriously overheat the brakes, reducing their effectiveness.
- For full braking effectiveness, operate both the front and rear brakes together.

Combined Braking System (CBS)

Your scooter's rear brake system is linked to the front brake. This means that operating the rear brake lever applies the rear brake and a portion of the front brake.

Operating the front brake lever applies only the front brake.

For full braking effectiveness, operate both the front and rear brakes together.

Wet or Rainy Conditions

Road surfaces are slippery when wet, and wet brakes further reduce braking efficiency.

Exercise extra caution when braking in wet conditions.

If the brakes get wet, apply the brakes while riding at low speed to help them dry.

Parking

● Park on a firm, level surface.
- If you must park on a slight incline or loose surface, park so that the scooter cannot move or fall over.
● Make sure that high-temperature parts cannot come into contact with flammable materials.
- Do not touch the engine, muffler, brakes and other high-temperature parts until they cool down.
- To reduce the likelihood of theft, always lock the handlebar and remove the key and close the shutter when leaving the scooter unattended.
Use of an anti-theft device is also recommended.

Riding Precautions

Parking with the Center Stand

  1. Stop the engine.
  2. To lower the center stand, stand on the left side of the scooter. Hold the left handle grip and the rear grip. Press down on the tip of the center stand with your right foot and, simultaneously, pull up and back.
  3. Turn the handlebar fully to the left.

Left handle grip Center stand Rear grip

  1. Turn the ignition switch to the 🔒 (Lock) position, remove the key and close the shutter. P. 26

Refueling and Fuel Guidelines

Follow these guidelines to protect the engine, fuel system and catalytic converter:

● Use only unleaded gasoline.
- Use recommended octane number. Using lower octane gasoline will result in decreased engine performance.
- Do not use fuels containing a high concentration of alcohol. ➡ P. 112
- Do not use stale or contaminated gasoline or an oil/gasoline mixture.
● Avoid getting dirt or water in the fuel tank.

Accessories & Modifications

We strongly advise that you do not add any accessories that were not specifically designed or approved for your scooter by Honda or make modifications to your scooter from its original design. Doing so can make it unsafe. Modifying your scooter may also void your warranty and make your scooter illegal to operate on public roads and highways. Before deciding to install accessories on your scooter be certain the modification is safe and legal.

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.

Do not pull a trailer with, or attach a sidecar to, your scooter. Your scooter was not designed for these attachments, and their use can seriously impair your scooter's handling.

Loading

Loading

  • Carrying extra weight affects your scooter's handling, braking and stability.
    Always ride at a safe speed for the load you are carrying.
    ● Avoid carrying an excessive load and keep within specified load limits.
    ● Tie all luggage securely, evenly balanced and close to the center of the scooter.
  • Do not place objects near the lights or the muffler.

Maximum weight capacity / Maximum luggage weight P. 118

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.

Caring for Your Scooter

Caring for Your Scooter

Frequent cleaning and polishing is important to ensure the life of your Honda. A clean scooter makes it easier to spot potential problems. In particular, seawater and salts used to prevent ice on roads promote the formation of corrosion. Always wash your scooter thoroughly after riding on coastal or treated roads.

Washing

Allow the engine, muffler, brakes, and other high-temperature parts to cool before washing.

  1. Rinse your scooter thoroughly using a low pressure garden hose to remove loose dirt.
  2. If necessary, use a sponge or a soft towel with mild cleaner to remove road grime.
    ▶ Clean the headlight lens, panels, and other plastic components with extra care to avoid scratching them. Avoid directing water into the air cleaner, muffler, and electrical parts.

  3. Thoroughly rinse your scooter with plenty of clean water and dry with a soft, clean cloth.

  4. After the scooter dries, lubricate any moving parts.

▶ Make sure that no lubricant spills onto the brakes or tires. Brake discs, pads, drum or shoes contaminated with oil will suffer greatly reduced braking effectiveness and can lead to a crash.

  1. Apply a coat of wax to prevent corrosion.

▶ Avoid products that contain harsh detergents or chemical solvents. These can damage the metal, paint, and plastic on your scooter.
Keep the wax clear of the tires and brakes.
If your scooter has any matte painted parts, do not apply a coat of wax to the matte painted surface.

Caring for Your Scooter

Washing Precautions

Follow these guidelines when washing:

● Do not use high-pressure washers:
▶ High-pressure water cleaners can damage moving parts and electrical parts, rendering them inoperable.
▶ Water in the air intake can be drawn into the throttle body and/or enter the air cleaner.
● Do not direct water at the muffler:
▶ Water in the muffler can prevent starting and causes rust in the muffler.
● Dry the brakes:
▶ Water adversely affects braking effectiveness. After washing, apply the brakes intermittently at low speed to help dry them.
● Do not direct water under the seat:
▶ Water in the under seat compartment can damage your documents and other belongings.

● Do not direct water at the air cleaner:
▶ Water in the air cleaner can prevent the engine from starting.
● Do not direct water near the headlight:
The headlight's inside lens may fog temporarily after washing or while riding in the rain. This does not impact the headlight function.
▶ Any condensation inside the headlight should dissipate after a few minutes of running the engine with the headlight(s) on. However, if you see a large amount of water or ice accumulated inside the lens(es), have your vehicle inspected by your dealer.
- Do not use wax or polishing compounds on matte painted surface:
▶ Use a soft cloth or sponge, plenty of water, and a mild detergent to clean matte painted surfaces. Dry with a soft clean cloth.

  • Do not use stiff brushes, steel wool, or cleaners containing abrasives.
    ● Avoid riding over or scraping against curbs.

Panels

Follow these guidelines to prevent scratches and blemishes:

● Wash gently using a soft sponge and plenty of water.
● To remove stubborn stains, use diluted detergent and rinse thoroughly with plenty of water.
● Avoid getting gasoline or detergents on the instruments, panels, or headlight.

Exhaust Pipe and Muffler

When the exhaust pipe and muffler are painted, do not use a commercially available abrasive kitchen cleaning compound. Use a neutral detergent to clean the painted surface on the exhaust pipe and muffler. If you are not sure if your exhaust pipe and muffler are painted, contact your dealer.

Storing Your Scooter

Storing Your Scooter

If you store your scooter outdoors, you should consider using a full-body motorcycle cover. If you won't be riding for an extended period, follow these guidelines:

  • Wash your scooter and wax all painted surfaces (except matte painted surfaces).
    Coat chrome pieces with rust-inhibiting oil.
  • Place your scooter on its center stand and position a block so that both tires are off the ground.
    ● After rain, remove the body cover and allow the scooter to dry.
  • Remove the battery (▶ P. 62) to prevent discharge. Charge the battery in a shaded, well-ventilated area.

▶ If you leave the battery in place, disconnect the negative ⊖ terminal to prevent discharge.

After removing your scooter from storage, inspect all maintenance items required by the Maintenance Schedule.

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

Transporting Your Scooter

Transporting Your Scooter

If your scooter needs to be transported, it should be carried on a motorcycle trailer or a flatbed truck or trailer that has a loading ramp or lifting platform, and motorcycle tie-down straps. Never try to tow your scooter with a wheel or wheels on the ground.

NOTICE

Towing your scooter can cause serious damage to the transmission.

You & the Environment

Owning and riding a scooter can be enjoyable, but you must do your part to protect the environment.

Choose Sensible Cleaners

Use a biodegradable detergent when you wash your scooter. Avoid aerosol spray cleaners that contain chlorofluorocarbons (CFCs) which damage the atmosphere's protective ozone layer.

You & the Environment

Recycle Wastes

Put oil and other toxic wastes in approved 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. Do not place used engine oil in the trash, or pour it down a drain or on the ground. Used oil, gasoline, coolant, and cleaning solvents contain poisons that can hurt refuse workers and contaminate drinking water, lakes, rivers, and oceans.

Vehicle Identification Number

Vehicle Identification Number

The VIN and engine serial number uniquely identify your scooter and are required in order to register your scooter. They may also be required when ordering replacement parts. You should record these numbers and keep them in a safe place.

Emission Control Systems

Emission Control Systems

Your scooter engine emits combustion byproducts, including carbon monoxide (CO), oxides of nitrogen (NOx), and hydrocarbons (HC). Gasoline evaporation also emits hydrocarbons. Controlling the production of NOx, CO, and HC is important for the environment.

Exhaust Emission Requirements

The U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) require that your scooter comply with applicable exhaust, crankcase, and fuel permeation emission standards during its useful life, when operated and maintained according to the instructions provided.

CARB also requires that your scooter comply with applicable evaporative emission requirements during its useful life, when

operated and maintained according to the instructions provided.

Compliance with the terms of the Distributor's Warranties for Honda Scooter Emission Control Systems is necessary in order to maintain a valid emissions system warranty.

The Vehicle Emission Control Information label is attached to the rear side of the center compartment. P. 38

Vehicle emission control information label

Continued

Emission Control Systems

Noise Emission Requirements

The EPA requires that scooters built after January 1, 1983 comply with applicable noise emission standards for one year or 3,730 miles (6,000 km) after the time of purchase when operated and maintained according to the instructions provided.

Exhaust Emission Control System

The exhaust emission control system includes the following components that should not need adjustment, although periodic inspection by your dealer is recommended.

PGM-FI System

The PGM-FI (programmed fuel injection) system uses sequential multiport fuel injection, and is comprised of air intake, engine control, fuel control, and exhaust control subsystems. The engine control module (ECM) uses sensors to determine how much air enters the engine, and then controls how much fuel to inject.

Ignition Timing Control System

The ignition timing control system adjusts the ignition timing to reduce the amount of HC, CO, and NOx produced.

Catalytic Converters

The exhaust system contains one or more catalytic converters. Catalytic converters use a catalyst to convert most of the harmful exhaust gas compounds into harmless compounds.

Crankcase Emissions 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 intake manifold.

Fuel Permeation Emission Control

The fuel tank, fuel hoses, and fuel vapor charge hoses use fuel permeation control technologies to prevent fuel vapor emissions. Tampering with these components to reduce or defeat the effectiveness of the fuel permeation technologies is prohibited.

Noise Emission Control System

TAMPERING WITH THE NOISE CONTROL SYSTEM IS PROHIBITED:

U. S. federal law prohibits 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.

Emission Control Systems

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

● Removal of, or puncturing the muffler, baffles, header pipes or any other component which conducts exhaust gases.
● Removal of, or puncturing of any part of the intake system.
● Lack of proper maintenance.
- Removing or disabling any emissions compliance component, or replacing any compliance component with a noncompliant component.

Problems Affecting Scooter Exhaust Emissions

Have your scooter inspected and repaired by your dealer if you experience any of the following symptoms:

● Hard starting or stalling after starting
- Rough idling
● Misfiring or backfiring during acceleration
● Poor engine performance and poor fuel economy

Catalytic Converter

Catalytic Converter

This scooter is equipped with a three-way catalytic converter. The catalytic converter contains precious metals that serve as catalysts in high temperature chemical reactions that convert hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) in the exhaust gasses into safe compounds.

A defective catalytic converter contributes to air pollution and can impair your engine's performance. A replacement unit must be an original Honda part or equivalent.

Follow these guidelines to protect your scooter's catalytic converter.

● Always use unleaded gasoline. Leaded gasoline will damage the catalytic converter.
- Keep the engine in good running condition. A poorly running engine can cause the catalytic converter to overheat causing damage to the converter or the scooter.
- If your engine is misfiring, backfiring, stalling, or otherwise not running properly, stop riding and turn off the engine. Have your scooter serviced as soon as possible.

Oxygenated Fuels

Oxygenated Fuels

Some conventional fuels blended with alcohol or an ether compound are available in some locales to help reduce emissions to meet clean air standards. These gasolines are collectively referred to as oxygenated fuels. If you plan to use oxygenated fuel, check that it is unleaded and meets the minimum octane rating and blend requirement.

The following fuel blends are EPA-approved and have been approved for use in your scooter:

● Ethanol (ethyl alcohol) up to 10% by volume.
▶ Gasoline containing ethanol may be marketed under the name Gasohol.
- Methanol (methyl alcohol) up to 5% by volume that contain cosolvents and corrosion inhibitors to protect the fuel system. Never use a blend containing more than 5%.

If you accidentally fill your fuel tank with an oxygenated fuel containing higher percentages, you may experience performance problems. To resolve the problem, have your dealer drain the fuel tank and replace with the correct fuel. Fuel system or performance problems resulting from the use of an oxygenated fuel containing higher percentages are not covered by your warranty.

NOTICE

Improper use of oxygenated fuels can damage metal, rubber, and plastic parts of your fuel system. Oxygenated fuel can also damage paint. Damage caused by spilled fuel is not covered by warranty.

If you notice any undesirable operating symptoms or performance problems, try a different brand of gasoline.
