8Never operate an ATV in fast flowing water or
in water deeper than that recommended in
this manual. Remember that wet brakes may
have reduced stopping ability. Test your
brakes after leaving water. If necessary, apply
them several times to let friction dry out the
linings.
8Always use the size and type tires specified in
this manual.
8Always maintain proper tire pressure as
described in this manual.
8Never modify an ATV through improper instal-
lation or use of accessories.

EBU00158Tires
Always use the recommended tires.wUse of improper tires on this ATV, or opera-
tion of this ATV with improper or uneven tire
pressure, may cause loss of control, increas-
ing your risk of accident.
Pay attention to the following.
1. The tires listed below have been
approved by Yamaha Motor Co., Ltd. for
this model. Other tire combinations are
not recommended.
2. The tires should be set to the recom-
mended pressure:
8Recommended tire pressure
Front 20 kPa (0.20 kgf/cm
2, 0.20 bar)
Rear 20 kPa (0.20 kgf/cm2, 0.20 bar)
Manufacturer Size Type
Front DUNLOP AT18 ×7–7 KT586
Rear DUNLOP AT18 ×8–7 KT587

8Check and adjust tire pressures when
the tires are cold.
8Tire pressures must be equal on both
sides.
3. Tire pressure below the minimum speci-
fied could cause the tire to dislodge
from the rim under severe riding condi-
tions. The following are minimums:
Front 17 kPa (0.17 kgf/cm
2, 0.17 bar)
Rear 17 kPa (0.17 kgf/cm2, 0.17 bar)
4. Use no more than the following pres-
sures when seating the tire beads.
Front 250 kPa (2.5 kgf/cm2, 2.5 bar)
Rear 250 kPa (2.5 kgf/cm2, 2.5 bar)
Higher pressures may cause the tire to
burst. Inflate the tires very slowly and
carefully. Fast inflation could cause the
tire to burst.

EBU00159How to measure tire pressure
Use the low-pressure tire gauge.NOTE:
The low-pressure tire gauge is included as stan-
dard equipment. Make two measurements of the
tire pressure and use the second reading. Dust
or dirt in the gauge could cause the first reading
to be incorrect.Set pressure with tires cold.
Set tire pressures to the following specifications:

Manual on page 5-23. Use of improper tires
on this ATV, or operation of this ATV with
improper or uneven tire pressure, may cause
loss of control, increasing your risk of an
accident.Do not operate at speeds too fast for your
skills or the conditions.wAlways go at a speed that is proper for the
terrain, visibility and operating conditions,
and your experience. Operating this ATV at

You are recommended to put this owner’s man-
ual and low-pressure tire gauge in the vinyl bag
and always carry them along with the owner’s
tool kit under the seat. The service information
included in this manual is intended to provide
you, the owner, with the necessary information
for completing your own preventive maintenance
and minor repairs. The tools provided in the
Owner’s tool kit are sufficient for this purpose,
except that a torque wrench is also necessary to
properly tighten nuts and bolts.NOTE:
If you do not have a torque wrench available
during a service operation requiring one, take
your machine to a Yamaha dealer to check the
torque settings and adjust them as necessary.
