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.

This section contains important information for safe riding of your motorcycle.
Please read this section carefully.
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
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.

Continued
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.
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.

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.

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 build-
up 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.

Safety Labels
Safety and information labels on your
motorcycle 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.

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.

Riding Precautions
Motorcycle Safety
10
● 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.
#
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.

#
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.
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.

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
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.

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.

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
operated and maintained according to the
instructions provided.
USA
Compliance with the terms of the
Distributor's Warranties for Honda Motorcycle
Emission Control Systems is necessary in order
to maintain a valid emissions system warranty.
The Vehicle Emission Control Information label
is located on the left side of the swingarm.

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.
#
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.

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.
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.
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.

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.
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

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.
