OWNER’S MANUAL & COMPETITION HANDBOOK

Introduction

Congratulations on choosing your Honda CR

motocross motorcycle.

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 CR, other property, or the

environment.

NOTICE

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.

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.

Your CR 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.

The official Honda Service Manual for your CR

is available (page 136). It is the same manual

your dealer uses. If you plan to do any service

on your CR beyond the standard maintenance

procedures in this manual, you will find the

Service Manual a valuable reference.

Be aware that motocross is a physically

demanding sport that requires more than just a

fine CR. 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.

If you have any questions, or if you ever need a

special service or repairs, remember that your

Honda dealer knows your CR best and is

dedicated to your complete satisfaction.

Before riding, take time to get acquainted with

your CR and how it works. To protect your

investment, we urge you to take responsibility for

keeping your CR 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.

Please report any change of address or ownership

to your Honda dealer so we will be able to

contact you concerning important production

information.

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.

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:

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.

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.
