GETTING TO KNOW YOUR ATV
This ATV is for recreation use. This section, Riding
your ATV, provides general ATV riding instructions
for recreational riding. The skills and techniques
described in this section, however, are appropriate
for all types of riding. Riding your ATV requires
special skills acquired through practice over a pe-
riod of time. Take the time to learn the basic tech-
niques well before attempting more difficult
maneuvers.
Riding your new ATV can be a very enjoyable ac-
tivity, providing you with hours of pleasure. But it is
essential to familiarize yourself with the operation
of the ATV to achieve the skill necessary to enjoy
riding safely. Before you begin to ride, be sure you
have read this Owner’s Manual completely and un-
derstand the operation of the controls. Pay partic-
ular attention to the safety information on pages
1-1–1-6. Please also read all caution and warning
labels on your ATV.
RIDE WITH CARE AND GOOD JUDGEMENT
Get training if you are inexperienced.
Beginners should get training from a certified in-
structor.
Become familiar with this ATV at slow speeds first,
even if you are an experienced operator. Do not at-
tempt to operate at maximum performance until
you are totally familiar with the ATV’s handling and
performance characteristics.
WARNING
EWB01380
Never operate this ATV without proper instruc-
tion. Beginning and inexperienced operators
should regularly practice the skills and the op-
erating techniques described in this Owner’s
Manual. The risk of an accident is greatly in-
creased if the operator does not know how to
operate the ATV properly in different situations
and on different types of terrain.
Riding your ATV requires skills acquired
through practice over a period of time.
Take the time to learn the basic techniques well
before attempting more difficult maneuvers.

dren of ATVs that are not recommended for

WARNING

EWB01420
Never consume alcohol or drugs before or
while driving this ATV.
Pre-operation checks
Always perform the pre-operation checks listed on
page 5-1 before riding for proper care of the ATV
and to ensure safety.
WARNING

EWB01430
Always inspect your ATV each time you use it
to make sure the ATV is in safe operating con-
dition. Always follow the inspection and main-
tenance procedures and schedules described
in the Owner’s Manual. Failure to inspect the
ATV before operating or failure to properly
maintain the ATV increases the possibility of
an accident or equipment damage.
WARNING

EWB01440
Always use the size and type tires specified in
the Owner’s Manual for this ATV on page 5-4.
Always maintain proper tire pressure as de-
scribed in the Owner’s Manual on page 5-5.Use of improper tires on this ATV, or operation
of this ATV with improper or uneven tire pres-
sure, may cause loss of control, increasing
your risk of an accident.
Do not operate at speeds too fast for your
skills or the conditions.
WARNING

EWB01450
Always go at a speed that is proper for the ter-
rain, visibility and operating conditions, and
your experience. Operating this ATV at speeds
too fast for your skills or the conditions in-
creases your chances of losing control of the
ATV, which can result in an accident.
Speed limiter
For riders less experienced with this model, the
throttle lever housing is equipped with a speed lim-
iter. The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and de-
creases the maximum speed of the ATV. Turning
in the adjusting screw decreases top speed, and
turning it out increases top speed. (See page 4-5.)

Yamaha recommends that all beginning riders
start off with the speed limiter turned in to limit the
amount of speed available while they learn. The
limiter may be gradually adjusted to increase max-
imum speed as the beginner becomes more famil-
iar with operating the ATV.
Loading and accessories
Use extra caution when riding the ATV with addi-
tional loads, such as accessories or cargo. The
ATV’s handling may be adversely affected. Re-
duce your speed when adding additional loads.
WARNING
EWB01460

Never exceed the stated load capacity for
this ATV.

Cargo should be properly distributed and se-
curely attached.

ing a trailer. Allow greater distance for brak-
ing.

er’s Manual for carrying cargo or pulling a
trailer.

While riding on unpaved public streets or roads
may be legal in your area, such operation can in-
crease the risk of collision with other vehicles.

know your country’s laws and regulations before
you ride on unpaved public streets or roads. Do not
ride on any paved public street, road or motorway.
WARNING

EWB01520
Never operate this ATV on any paved street,paved road or motorway. You can collide with
another vehicle. In many areas, it is illegal to
operate ATVs on public streets, roads and
highways.

unfamiliar areas. Stay alert for
holes, rocks, or
roots
in the terrain, and
other hidden hazards
which may cause the ATV to upset.WARNING

make you more visible when operating in areas
where you might not be seen by other vehicles.
Watch carefully for other vehicles.
Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting per-
mission.Select a large, flat, unpaved area to become famil-
iar with your ATV. Make sure that this area is free
of obstacles and other riders. You should practice
control of the throttle, brakes, and turning tech-
niques in this area before trying more difficult ter-
rain. Always avoid riding on paved surfaces: the
ATV is designed for use on unpaved surfaces only,
and handling maneuvers are more difficult to per-
form on pavement.

page 6-1 to start the engine. Once it has warmed
up you are ready to begin riding your ATV. Re-
member that the engine and exhaust pipe will be
hot when riding and afterwards; do not allow skin
