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
motorcycle for off-road use by one rider only.
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 CRF, other property, or the environment.
Unless you are mechanically qualified and have
the proper tools, you should see your dealer for the
service and adjustment procedures discussed in
this manual.
An official Honda Service Manual for your CRF is
available (page 182). 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 an official Honda
Service Manual a valuable reference.
Read the Warranties Booklet (page 183)
thoroughly 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.
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 dealer so we will be able to contact you
concerning important product information.
