Honda CRF250R

OWNER’S MANUAL & COMPETITION HANDBOOK

Introduction

Congratulations on choosing your Honda CRF

motocross 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 CRF is a high performance racing

motorcycle that utilizes the latest motocross

technology and is intended for competition use in

sanctioned, closed-course events by experienced

riders only.

Be aware that motocross is a physically

demanding sport that requires more than just a

fine motorcycle. To do well, you must be

excellent physical condition and be a skillful

rider. For the best results, work diligently on

your physical conditioning and practice

frequently.

Before riding, take time to get acquainted with

your CRF 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.

The official Honda Service Manual for your CRF

is available (page 152). 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.

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.

Happy riding!

Introduction

A Few Words About Safety

Your safety, and the safety of others, is very important. And operating this motorcycle safely is an important responsibility.

To help you make informed decisions about safety, this manual contains a section devoted to

Motorcycle Safety, as well as a number of Safety Messages

throughout the manual.

Safety Messages are preceded by a safety alert symbol and one of three signal words:

DANGER, WARNING, or CAUTION.

These signal words mean:

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

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

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

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

judgement.

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.

As an experienced rider, you know there is much

you can do to protect yourself when you ride.

The following are a few precautions we consider

most importsnt.

Never Carry a Passenger.

Your CRF is designed for one operator only.

Carring a passenger can cause an accident in

which you and others can be hurt.

Wear Protective Gear.

Whether you’re practicing to improve your skills,

or riding in competition, always wear an

approved helmet, eye protection, and proper

protective gear.

Take Time to Get to Know Your CRF.

Because every motorcycle is unique, take time to

become thoroughly familiar with how this one

operates and responds to your commands before

placing your machine, and yourself, in

competition.

Learn and Respect Your Limits.

Never ride beyond your personal abilites or faster

than conditions warrant. Remember that alcohol,

drugs, illness and fatigue can reduce your ability

to perform well and ride safety.

Dont’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.

Keep your Honda in Safe Condition.

Maintaining your CRF properly is critical to your

safety. A loose bolt, for example, can cause a

breakdown in which you can be seriously

injured.

handling, stability, and braking, making it unsafe

to ride.

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.

8 Before Riding

Are You Ready to Ride?

Before riding your CRF for the first time, we

strongly recommend that you read this owner’s

manual, make sure you understand the safety

messages, and know how to operate the controls.

Before each ride, it’s also important to make sure

you and your CRF are both ready to ride.

For information about suspension, carburetor,

and other adjustments, see page 93.

Whether you’re preparing for competition or for

practice, always make sure you are.

• In good physical and mental condition

• Free of alcohol and drugs

• Wearing an approved helmet, eye protection,

and other appropriate riding gear

Although complete protection is not possible,

wearing the proper gear can reduce the chance or

severity of injury when you ride.

WARNING

Not wearing a helmet increases the

chance of serious injury or death in a

crash.

Be sure you always wear a helmet, eye

protection and other protective apparel

when you ride.
