For ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or the
figures given in hours.
For ATVs not equipped with an odometer or
hour meter, follow the figures given in hours.There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 20
hours of riding. For this reason, you should read
the following material carefully.
Since the engine is brand new, do not put an ex-
cessive load on it for the first 320 km (200 mi) or 20
hours. The various parts in the engine wear and
polish themselves to the correct operating clear-
ances. During this period, prolonged full-throttle
operation or any condition that might result in en-
gine overheating must be avoided.

EBU20760Parking on a slope
WARNING
EWB00830Avoid parking on hills or other inclines. Park-
ing on a hill or other incline could cause the
ATV to roll out of control, increasing the
chance of an accident. If you must park on an
incline, place the ATV transversely across the
incline, shift the drive select lever to the for-
ward position, stop the engine, apply the park-
ing brake, and then block the front and rear
wheels with rocks or other objects.1. Parking brake lock plate

EBU20910Accessories and loading EBU20921Genuine Yamaha Accessories
Choosing accessories for your ATV is an important
decision. Genuine Yamaha Accessories, which
are available only from a Yamaha dealer, have
been designed, tested, and approved by Yamaha
for use on your ATV. Many companies with no con-
nection to Yamaha manufacture parts and acces-
sories or offer other modifications for Yamaha
vehicles. Yamaha is not in a position to test the
products that these aftermarket companies pro-
duce. Therefore, Yamaha can neither endorse nor
recommend the use of accessories not sold by
Yamaha or modifications not specifically recom-
mended by Yamaha, even if sold and installed by
a Yamaha dealer.
Aftermarket parts, accessories, and modifica-
tions
While you may find aftermarket products similar in
design and quality to genuine Yamaha Accesso-
ries, recognize that some aftermarket accessories
or modifications are not suitable because of poten-
tial safety hazards to you or others. Installing after-

6market products or having other modifications
performed to your ATV that change any of the ve-
hicle’s design or operation characteristics can put
you and others at greater risk of serious injury or
death. You are responsible for injuries related to
changes in the vehicle.
Keep the following in mind when considering an
accessory or operating an ATV which has acces-
sories.

Accessories should be rigidly and securely
mounted. An accessory which can shift position
or come off while you are riding could affect your
ability to control the ATV.
Do not mount an accessory where it could inter-
fere with your ability to control the ATV. Exam-
ples include (but are not limited to) a heavy or
bulky object attached to the handlebars which
could make steering difficult, an accessory that
limits your ability to move around on the seat, or
one that limits your view.
Use extra caution when riding an ATV with ac-
cessories. The ATV may handle differently than
it does without accessories.
EBU21061Loading
WARNING
EWB00820Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and se-
curely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.Cargo or a trailer can change the stability and han-
dling of an ATV.
You must use common sense and good judgment
when carrying cargo or towing a trailer. Keep the
following points in mind:
Never exceed the weight limits shown. An over-
loaded ATV can be unstable.

Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath-
room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad-
just the load in the trailer, if necessary, to reduce
the weight on the hitch. If you are carrying cargo
and towing a trailer, include the tongue weight in
the maximum ATV load limit.

Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
Make sure the load does not interfere with con-
trols or your ability to see where you are going.
Ride more slowly than you would without a load.
The more weight you carry, the slower you
should go.
Allow more braking distance. A heavier ATV
takes longer to stop.
Avoid making sharp turns unless at very slow
speeds.
Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV. MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
210.0 kg (463 lb)

EBU21465GETTING TO KNOW YOUR ATV
This ATV is for recreation and utility use. This sec-
tion, 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 period of time. Take the time to learn the ba-
sic techniques 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
2-1–2-4. Also read all warning and notice labels on
your ATV.RIDE WITH CARE AND GOOD JUDGMENT
Get training if you are inexperienced.
WARNING
EWB01381
Do not operate this ATV or allow anyone else
to operate it without proper instruction. The
risk of an accident is greatly increased if the
operator does not know how to operate the
ATV properly in different situations and on
different types of terrain.
Do not operate this ATV at speeds too fast
for your skills or the conditions, as this in-
creases your chances of losing control of
the ATV and an accident. Always go at a
speed that is proper for the terrain, visibility
and operating conditions, and your experi-
ence.Beginning and inexperienced operators should
regularly practice the skills and the operating tech-
niques described in this Owner’s Manual.

7Riding your ATV requires skills acquired
through practice over a period of time.
Do not attempt to operate at maximum perfor-
mance until you are totally familiar with the ATV’s
handling and performance characteristics. Take
the time to learn the basic techniques well before
attempting more difficult maneuvers. Become fa-
miliar with this ATV at slow speeds first, even if you
are an experienced operator.
Not recommended for children under 16 years
of age.
WARNING
EWB01390A child under 16 should never operate an ATV
with engine size greater than 90 cc. Use by chil-
dren of ATVs that are not recommended for
their age can lead to severe injury or death of
the child.
This ATV is designed to carry the operator and
cargo only – passengers prohibited.
The long seat is to allow the operator to shift posi-
tion as needed during operation. It is not for carry-
ing passengers. WARNING! Never carry a
passenger. Carrying a passenger on this ATV
greatly reduces your ability to balance and
control this ATV. You could have an accident,
resulting in severe injury or death to you
and/or your passenger.
