A Few Words About Safety

Your safety, and the safety of others, is very important. Operating this motorcycle 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 motorcycle. You must use your own good judgment.
You will find important safety information in a variety of forms, including:  Safety labels on the motorcycle  Safety Messages preceded by a safety alert
symbol and one of three signal words: DANGER, WARNING, or CAUTION. These signal words mean:

3DANGER
You WILL be KILLED or SERIOUSLY HURT if you don't follow instructions.
3WARNING
You CAN be KILLED or SERIOUSLY HURT if you don't follow instructions.
3CAUTION
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 motorcycle, other property, or the environment.

Motorcycle Safety

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. 2 P. 9

Safety Guidelines
Before Riding Make sure that you are physically fit, mentally focused and free of alcohol and drugs. Check that you and your passenger are both wearing an approved motorcycle helmet and protective apparel. Instruct your passenger on holding onto the seat strap or your waist, leaning with you in turns, and keeping their feet on the footpegs, even when the motorcycle is stopped.
Take Time to Learn & Practice Even if you have ridden other motorcycles, practice riding in a safe area to become familiar with how this motorcycle works and handles, and to become accustomed to the motorcycle's size and weight.

Motorcycle Safety

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.
USA Other riding tips can be found in the You and Your Motorcycle Riding Tips booklet that came with your motorcycle.
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.
4

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.

Motorcycle Safety

Safety Guidelines

Keep Your Honda in Safe Condition
It's important to keep your motorcycle properly maintained and in safe riding condition. Inspect your motorcycle before every ride and perform all recommended maintenance. Never exceed load limits (2 P. 15), and do not modify your motorcycle or install accessories that would make your motorcycle unsafe (2 P. 14).

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 motorcycle. 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 motorcycle may have suffered damage that is not immediately apparent. Have your motorcycle 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 motorcycle inside a garage or other enclosure.

3WARNING
Running the engine of your motorcycle while in an enclosed or even partially enclosed area can cause a rapid buildup of toxic carbon monoxide gas.
Breathing this colorless, odorless gas can quickly cause unconsciousness and lead to death.
Only run your motorcycle's engine when it is located in a well ventilated area outdoors.

Riding Precautions
# Boots or Riding Shoes
Sturdy boots with non-slip soles and ankle protection
# Jacket and Pants
Protective, highly visible, long-sleeved jacket and durable long pants for riding (or a protective suit)

Riding Precautions
Break-in Period During the first 300 miles (500 km) of running, follow these guidelines to ensure your motorcycle's future reliability and performance.  Avoid full-throttle starts and rapid
acceleration.  Avoid hard braking and rapid down-shifts.  Ride conservatively.
Brakes Observe the following guidelines:  Avoid excessively hard braking and
downshifting. u Sudden braking can reduce the
motorcycle's stability. u Where possible, reduce speed before
turning; otherwise you risk sliding out.

10

Motorcycle Safety

 Exercise caution on low traction surfaces. u The tires slip more easily on such surfaces and braking distances are longer.
 Avoid continuous braking. u Repeated braking, such as when descending long, steep slopes can seriously overheat the brakes, reducing their effectiveness. Use engine braking with intermittent use of the brakes to reduce speed.
 For full braking effectiveness, operate both the front and rear brakes together.

Riding Precautions
# Anti-lock Brake System (ABS)
CB300RA only
This model is equipped with an Anti-lock Brake System (ABS) designed to help prevent the brakes from locking up during hard braking. The ABS functions with information provided by the IMU (Inertia Measurement Unit).  ABS does not reduce braking distance. In
certain circumstances, ABS may result in a longer stopping distance.  ABS does not function at speeds below 6 mph (10 km/h).  The brake lever and pedal may recoil slightly when applying the brakes. This is normal.  Always use the recommended front/rear tires and sprockets to ensure correct ABS operation.

Continued 11

Motorcycle Safety

Riding Precautions
# Engine Braking
Engine braking helps slow your motorcycle down when you release the throttle. For further slowing action, downshift to a lower gear. Use engine braking with intermittent use of the brakes to reduce speed when descending long, steep slopes.
# 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.
12

Parking
 Park on a firm, level surface.  If you must park on a slight incline or loose
surface, park so that the motorcycle 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 when leaving the motorcycle unattended. Use of an anti-theft device is also recommended.
# Parking with the Side Stand
1. Stop the engine. 2. Push the side stand down. 3. Slowly lean the motorcycle to the left until its
weight rests on the side stand.

Motorcycle Safety

4. Turn the handlebar fully to the left. u Turning the handlebar to the right reduces stability and may cause the motorcycle to fall.
5. Turn the ignition switch to the LOCK position and remove the key. 2 P. 43

Riding Precautions
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. 2 P. 140  Do not use stale or contaminated gasoline or an oil/gasoline mixture.  Avoid getting dirt or water in the fuel tank.

Motorcycle Safety

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

3WARNING
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 motorcycle. Your motorcycle was not designed for these attachments, and their use can seriously impair your motorcycle's handling.

Caring for Your Motorcycle

Caring for Your Motorcycle
Frequent cleaning and polishing is important to ensure the life of your Honda. A clean motorcycle 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 motorcycle 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 motorcycle 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. u 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 motorcycle with plenty of clean water and dry with a soft, clean cloth. 4. After the motorcycle dries, lubricate any moving parts. u 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. 5. Lubricate the drive chain immediately after washing and drying the motorcycle. 6. Apply a coat of wax to prevent corrosion. u Avoid products that contain harsh detergents or chemical solvents. These can damage the metal, paint, and plastic on your motorcycle. Keep the wax clear of the tires and brakes. u If your motorcycle has any matte painted parts, do not apply a coat of wax to the matte painted surface.

Caring for Your Motorcycle
# Washing Precautions
Follow these guidelines when washing:  Do not use high-pressure washers:
u High-pressure water cleaners can damage moving parts and electrical parts, rendering them inoperable.
u 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: u Water in the muffler can prevent starting and causes rust in the muffler.
 Dry the brakes: u 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: u Water in the under seat compartment can damage your documents and other belongings.

 Do not direct water at the air cleaner: u Water in the air cleaner can prevent the engine from starting.
 Do not direct water near the headlight: u The headlight's inside lens may fog temporarily after washing or while riding in the rain. This does not impact the headlight function. 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: u Use a soft cloth or sponge, plenty of water, and a mild detergent to clean matte painted surfaces. Dry with a soft clean cloth.

Storing Your Motorcycle
Storing Your Motorcycle
If you store your motorcycle 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 motorcycle and wax all painted
surfaces (except matte painted surfaces). Coat chrome pieces with rust-inhibiting oil.  Lubricate the drive chain. 2 P. 65  Place your motorcycle on a maintenance stand and position a block so that both tires are off the ground.  After rain, remove the body cover and allow the motorcycle to dry.  Remove the battery (2 P. 73) to prevent discharge. Fully charge the battery and then place it in a shaded, well-ventilated area. u If you leave the battery in place,
disconnect the negative - terminal to prevent discharge.

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

You & the Environment

You & the Environment
Owning and riding a motorcycle can be enjoyable, but you must do your part to protect the environment.
Choose Sensible Cleaners Use a biodegradable detergent when you wash your motorcycle. Avoid aerosol spray cleaners that contain chlorofluorocarbons (CFCs) which damage the atmosphere's protective ozone layer.

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.

Emission Control Systems
Emission Control Systems
Your motorcycle 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), the California Air Resources Board (CARB), and Environment and Climate Change Canada (ECCC) require that your motorcycle 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 motorcycle comply with applicable evaporative emission requirements during its useful life, when

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.

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

# Secondary Air Injection System
The secondary air injection system adds filtered air into the exhaust gas to help improve emission control performance.
# 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.

Emission Control Systems

Evaporative Emission Control System
50 STATE (meets California)
An evaporative emissions control system uses a canister filled with charcoal to adsorb fuel vapor from the fuel tank while the engine is off. The vapor is drawn into the engine and burned while riding.

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.

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 front cylinder head, air cleaner housing and throttle body.

Noise Emission Control System
# TAMPERING WITH THE NOISE CONTROL
SYSTEM IS PROHIBITED: U. S. federal law prohibits, and 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.

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 Motorcycle Exhaust Emissions Have your motorcycle 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
138

Catalytic Converter
This motorcycle 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.

Catalytic Converter
Follow these guidelines to protect your motorcycle'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 motorcycle.  If your engine is misfiring, backfiring, stalling, or otherwise not running properly, stop riding and turn off the engine. Have your motorcycle 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 motorcycle:  Ethanol (ethyl alcohol) up to 10% by volume.
u 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.
