Introduction
Congratulations on choosing your Honda CRF
off-road motorcycle.
When you own a Honda, you’re part of a
worldwide family of satisfied customers-people
who appreciate Honda’s reputation for building
quality into every product.
Your Honda was designed as a recreational CRF
for off-road use by one rider only.
Before riding, take time to get acquainted with
your motorcycle and how it works. To protect
your investment, we urge you to take
responsibility for keeping your CRF well
maintained. Scheduled service is a must, of
course. But it’s just as important to observe the
break-in guidelines, and perform all the pre-ride
and other periodic checks detailed in this manual.
You should also read the owner’s manual before
you ride. It’s full of facts,
instructions, safety information, and helpful tips.
To make it easy to use, the manual
contains a table of contents, a detailed list of
topics at the beginning of each section, and an
index at the back of the book.
As you read this manual, you will find
information that is preceded by a
symbol. This information is intended to help you
avoid damage to your Honda, other property, or
the environment.
Unless you are mechanically qualified and have
the proper tools, you should see your Honda
dealer for the service and adjustment procedures
discussed in this manual.
NOTICE
The official Honda Service Manual for your CRF
is available (page 168). It is the same manual
your dealer uses. If you plan to do any service
on your CRF beyond the standard maintenance
procedures in this manual, you will find the
Service Manual a valuable reference.
Read the Warranties Booklet (page 169)
throughly so you understand the coverages that
protect your new Honda and are aware of your
rights and responsibilities.
This motorcycle has no cooling fan. For this
reason, engine overheating and coolant loss will
occur if the engine is kept idling too long when
hot. Additionally, when riding in mud or sand, or
any condition that causes high engine load at low
vehicle speed, the time it takes for the engine to
overheat will be shortened, especially when the
ambient temperature is high. Continuing to
operate the unit in these conditions will result in
engine damage.
An optional cooling fan is available and is
recommended for units that will be operated in
conditions with high engine load and low vehicle
speed.
Whenever you ride, tread lightly. By staying on
established trails and riding only in approved
areas, you help protect the environment and keep
off-road riding areas open for the future.
If you have any questions, or if you ever need a
special service or repairs, remember that your
Honda dealer knows your CRF best and is
dedicated to your complete satisfaction.
Please report any change of address or ownership
to your Honda dealer so we will be able to
contact you concerning important production
information.

Important Safety Information
Important Safety Precautions
Your CRF can provide many years of pleasure, if
you take responsibility for your own safety and
understand the challenges you can meet in
competitive racing.
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 most
important.
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
recommended that you wear eye protection,
sturdy boots, gloves, and other protective gear.
Never Carry a Passenger. Your CRF 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 motorcycle.
Ride Off-Road Only. Your CRF is designed and
manufactured for off-road use only. The tires are
not made for pavement, and the CRF 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 CRF across.
Always Wear Protective Gear. We recommend
that you wear sturdy boots, gloves, and other
protective gear. The exhaust system becomes
very hot during operation, and it remains hot
after operation. Never touch any part of the hot
exhaust system. Wear clothing that fully covers
your legs.
Keep Your Honda In Safe Condition. It’s
important to keep your CRF 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 CRF before every ride
and perform all recommended maintenance.
2 Motorcycle Safety
Do not wear loose clothing which could catch on
the control levers, kickstarter, footpegs, drive
chain, or wheels.
Take Time to Learn and Practice. Developing
off-road riding skills is a gradual, step-by-step
process. Start by practicing at low speed in a safe
area and slowly build your skills.
Personal instruction from an experienced rider
can also be valuable.
If you need assistance, ask your dealer about
riding groups in your area.
Also be sure to read the
Tips & Practice Guide
for the Off-Highway Motorcyclist
booklet that
came with your CRF (USA only).
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.
Ride within Your Limits. Pushing limits is
another major cause of motorcycle accidents.
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 safety.
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.
001-030.qxd06.7.414:11ページ2
Loading
Your CRF was designed as a rider-only
motorcycle. 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 CRF.
In addition, exceeding the weight limits or
carrying an unbalanced load can seriously affect
your CRF’s handling, braking, and stability.
Adding accessories or making modifications that
change this CRF’s design and performance can
also make it unsafe. Also, the weight of any
accessories will reduce the maximum load the
motorcycle can carry.
More specific information on load limits,
accessories, and modifications follows.
Loading
How much weight you put on your CRF, and
how you load it, are important to your safety. If
you decide to carry cargo, you should be aware
of the following information.
Loading Guidelines
As discussed on page 2, we recommended that
you do not carry any cargo on this motorcycle.
However, if you decide to carry cargo, ride at
reduced speeds and follow these commonsense
guidelines:
• Keep cargo small and light. Make sure it
cannot easily be caught on brush or other
objects, and that it does not interfere with
your ability to shift position to maintain
balance and stability.
• Place weight as close to the center of the
motorcycle as possible.
• Do not attach large or heavy items (such as a
sleeping bag or tent) to the handlebar, fork, or
front fender.
• Check that both tires are inflated properly.
Motorcycle Safety 3
WARNING
Overloading or carrying a passenger can
cause a crash and you can be seriously
hurt or killed.
Follow all loading guidelines in this
manual.
001-030.qxd06.7.414:11ページ3
Accessories & Modifications
Accessories
We strongly recommend that you use only
genuine Honda accessories that have been
specifically designed and tested for your CRF.
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 this guideline:
• Make sure the accessory does not reduce
ground clearance and lean angle, limit
suspension travel or steering travel, alter your
riding position, or interfere with operating any
controls.
Modifications
We strongly advise you not to remove any
original equipment or modify your CRF in any
way that would change its design or operation.
Such changes could seriously impair your CRF’s
handling, stability, and braking, making it unsafe
to ride.
We also advice 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 the
motorcycle illegal in your area.
4 Motorcycle Safety
Accessories & Modifications
Modifying your CRF or using non-Honda
accessories can make your CRF 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 modifications and
accessories.

Shifting Gears
Remember to close the throttle and pull the
clutch lever in completely before shifting.
Improper shifting may damage the engine,
transmission, and drive train.
Learning when to shift gears comes with
experience. Upshift to a higher gear or reduce
throttle before engine rpm (speed) gets too high.
Downshift to a lower gear before you feel the
engine laboring (lugging) at low rpm.
Downshifting can help slow your motorcycle,
especially on downhills. However, downshifting
when engine rpm is too high can cause engine
damage.
To prevent transmission damage, do not coast or
tow the motorcycle for long distances with the
engine off.
NOTICE
Basic Operating Instructions 17
Your CRF has five forward gears in a one-down,
four-up shift pattern.
To start riding, after the engine has been warmed
and the side stand raised.
1. Close the throttle and pull the front brake
lever in.
2. Pull the clutch lever all the way in.
3. Depress the shift lever from neutral down to
first gear.
4. Release the front brake. Gradually open the
throttle while you slowly release the clutch
lever. If the engine rpm (speed) is too low
when you release the clutch lever, the engine
will stall.
If the engine rpm (speed) is too high or you
release the clutch lever too quickly, your CRF
may lurch forward.
5. When you attain a moderate speed, close the
throttle, pull the clutch lever in, and raise the
shift lever. After shifting, release the clutch
lever and apply the throttle.
6. To continue shifting up to each higher gear,
repeat step 5.
7. To shift down to a lower gear, close the
throttle, pull the clutch lever in, and depress
the shift lever. After shifting, release the
clutch lever and apply the throttle.
NOTICE
NOTICE
001-030.qxd06.7.414:11ページ17
Braking
To slow or stop, apply the front brake lever and
rear brake pedal smoothly, while downshifting to
match your speed. Gradually increase braking as
you feel the brakes slowing your speed. To
prevent stalling the engine, pull the clutch lever
in before coming to a complete stop. For support,
put your left foot down first, then your right foot
when you are through using the rear brake pedal.
For maximum braking, close the throttle and
firmly apply the front brake lever and rear brake
pedal controls.
Applying the brakes too hard may cause the
wheels to lock and slide, reducing control of your
CRF. If this happens, release the brake controls,
steer straight ahead until you regain control, then
reapply the brakes more gently.
Generally, reduce your speed or complete
braking before beginning a turn. Avoid braking or
closing the throttle quickly while turning. Either
action may cause one or both wheels to slip. Any
wheel slip will reduce your control of your CRF.
When riding in wet or raining conditions, or on
loose surfaces, the ability to maneuver and stop
will be reduced. All of your actions should be
smooth under these conditions. Rapid
acceleration, braking, or turning may cause loss
of control. For your safety, exercise extreme
caution when braking, accelerating, or turning.
When descending a long, steep grade, use engine
compression braking by downshifting, with
intermittent use of both brakes.

24 Servicing Your Honda
WARNING
Improperly maintaining this motorcycle 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.
The Importance of Maintenance
A well-maintained motorcycle is essential for
safe, economical, and trouble-free riding. It will
also help reduce air pollution. Careful pre-ride
inspections and good maintenance are especially
important because your CRF is designed to be
ridden over rough off-road terrain.
To help you properly care for your CRF, 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 CRF to severe use or ride in unusually wet
or dusty areas.
Frequent servicing of the air cleaner is especially
important to help you avoid a possible costly
engine repair.
If your CRF overturns or is involved in a crash,
be sure your Honda dealer inspects all major
parts, even if you are able to make some repairs.
Remember, proper maintenance is your
responsibility. Be sure to inspect your CRF
before each ride and follow the Maintenance
Schedule in this section.

Maintenance Safety
This section includes instructions on how to
perform some important maintenance tasks.
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.
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 motorcycle 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 help prevent the motorcycle from falling
over, park it on a firm, level surface, using a
side stand or an optional workstand to provide
support.
• To reduce the possibility of a fire or
explosion, be careful when working around
gasoline. Use only a non-flammable (high
flash point) solvent such as kerosene —not
gasoline— to clean parts. Keep cigarettes,
sparks, and flames away from all fuel-related
parts.
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.
