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.
8Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed
and securely attached. Reduce speed and fol-
low instructions in this manual for carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.

Tires
Always use the recommended tires.
w
Use 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 AT16 ×7–7 KT145
Rear DUNLOP AT16 ×8–7 KT145

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 230 kPa (2.3 kgf/cm
2, 2.3 bar)
Rear 230 kPa (2.3 kgf/cm2, 2.3 bar)
Higher pressures may cause the tire to
burst. Inflate the tires very slowly and
carefully. Fast inflation could cause the
tire to burst.

How 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:

w
Always use the size and type tires specified
in the Owner’s Manual for this vehicle on
pages 5-19–5-21.
Always maintain proper tire pressure as
described in the Owner’s 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 con-
trol, increasing your risk of an accident.
Do not operate at speeds too fast for your
skills or the conditions.
w
Always go at a speed that is proper for the
terrain, visibility and operating conditions,
and your experience. Operating this ATV at
speeds too fast for your skills or the condi-
tions increases your chances of losing con-
trol of the ATV, which can result in an acci-
dent.
