The design and manufacture of this Yamaha motorcycle fully comply with the emissions standards for clean air applicable

recommended maintenance schedules and operating instructions contained within this manual.

WARNING

EWA10031
Please read this manual carefully and completely before operating this motorcycle.
WARNING

EWA14351
This motorcycle is designed and manufactured for off-road use only. It is illegal to operate this motorcycle on any
public street, road or highway. Such use is prohibited by law. This motorcycle complies with almost all state
off-highway noise level and spark arrester laws and regulations. Please check your local riding laws and regulations
before operating this motorcycle.
AN IMPORTANT SAFETY MESSAGE:

Read this manual carefully and completely before operating this motorcycle. Make sure you understand all instructions.

Pay close attention to the warning and notice labels on the motorcycle.

Never operate a motorcycle without proper training or instruction.

Weight of the rider should not exceed 25 kg (55 lb).

INTRODUCTION
AN IMPORTANT NOTE TO PARENTS:
This motorcycle is not a toy. Before you let your child ride this motorcycle, you should understand the instructions and warn-
ings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ in skills, physical abil-
ities, and judgment. Some children may not be able to operate a motorcycle safely. Parents should supervise their child’s
use of the motorcycle at all times. Parents should permit continued use only if they determine that the child has the ability to
operate the motorcycle safely.
Your motorcycle was delivered with an adjustable speed limiter and power reduction plate. Yamaha recommends that all
beginners start off with the speed limiter adjusting screw turned in and the power reduction plate installed in the exhaust man-
ifold to limit the power available while they learn. The limiter screw may be gradually turned out to increase maximum speed
as the beginner becomes more familiar with operating the motorcycle. Parents should decide when to adjust the motorcycle
for more power as their youngster’s riding skills improve. Once the rider can operate with skill at the top speed permitted by
adjusting the speed limiter alone, the power reduction plate can be removed. Since removal of this plate will result in a sig-
nificant increase in power, turn the speed limiter back in again; adjust it out in stages as you did before.
Motorcycles are single track vehicles. Their safe use and operation are dependent upon the use of proper riding
techniques as well as the expertise of the operator. Every operator should know the following requirements before
riding this motorcycle.
He or she should:


Obtain thorough instructions from a competent source on all aspects of motorcycle operation.

Observe the warnings and maintenance requirements in this Owner’s Manual.

Obtain qualified training in safe and proper riding techniques.

Obtain professional technical service as indicated in this Owner’s Manual and/or when made necessary by mechanical
conditions.

SAFETY INFORMATION
EAU40933
Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements before
riding this motorcycle.
He or she should:

Obtain thorough instructions from
a competent source on all aspects
of motorcycle operation.

Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.

Obtain qualified training in safe
and proper riding techniques.

Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.
Safe Riding
Perform the pre-operation checks eachtime you use the vehicle to make sure it
is in safe operating condition. Failure to
inspect or maintain the vehicle properly
increases the possibility of an accident
or equipment damage. See page 4-1
for a list of pre-operation checks.

This motorcycle is designed for
off-road use only, therefore, it is il-
legal to operate it on public streets,
roads, or highways, even a dirt or
gravel one. Off-road use on public
lands may be illegal. Please check
local regulations before riding.

This motorcycle is designed to car-
ry the operator only. No passen-
gers.

The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did
not see the motorcycle. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:

Wear a brightly colored jacket.

Use extra caution when you are
approaching and passing
through intersections, since in-
tersections are the most likely
places for motorcycle accidents
to occur.

Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.

Many accidents involve inexperi-
enced operators.

Make sure that you are qualified
and that you only lend your mo-
torcycle to other qualified opera-
tors.

Know your skills and limits.
Staying within your limits may
help you to avoid an accident.

We recommend that you prac-
tice riding your motorcycle until
you have become thoroughly fa-
miliar with the motorcycle and all
of its controls.

Many accidents have been caused
by error of the motorcycle opera-
tor. A typical error made by the op-
erator is veering wide on a turn
due to excessive speed or under-
