5-PRE-OPERATION CHECKSOwners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate
quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or
loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual in-
spection, you check the following points before each ride.

7 Tire inspection
Always check the tires before operating
the motorcycle. If center tread depth
reaches the limit as shown, if the tire
has a nail or glass fragments in it, or if
the side wall is cracked, contact a
Yamaha dealer immediately and have
the tire replaced.
EW000079
WARNING
@ Operating the motorcycle with ex-
cessively worn tires decrease riding
stability and can lead to loss of con-
trol. Have excessively worn tires re-
placed by a Yamaha dealer
immediately. Brakes, tires, and relat-
ed wheel parts replacement should
be left to a Yamaha Service Techni-
cian. @CE-26ENOTE:@ These limits may be different by regula-
tion from country to country. If so, con-
form to the limits specified by the
regulations of your own country. @

This motorcycle is equipped with tube-
less tires, tire valves and cast wheels.
EW000132
WARNING
@ After extensive tests, the tires men-
tioned below have been approved
by Yamaha Motor Co., Ltd. for this
model. No guarantee for handling
characteristics can be given if tire
combinations other than what is ap-
proved are used on this motorcycle.
The front and rear tires should be of
the same manufacture and design.
Always use the tire valves and valvecores listed below. Be sure to install
the valve caps securely, as these
are important to prevent air pres-
sure leakage.
@CE-41E
CE-42EEAU01230
WheelsTo ensure maximum performance,
long service, and safe operation, note
the following:l
Always inspect the wheels before
a ride. Check for cracks, bends or
warpage of the wheels. If any ab-
normal condition exists in a wheel,
consult a Yamaha dealer. Do not
attempt even small repairs to the
wheel. If a wheel is deformed or
cracked, it must be replaced.
l
Tires and wheels should be bal-
anced whenever either one is
changed or replaced. Failure to
have a wheel balanced can result
in poor performance, adverse han-
dling characteristics and short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be broken in for it to
develop its optimal characteristics.

Steering inspectionPeriodically inspect the condition of the
steering. Worn out or loose steering
bearings may be dangerous. Place a
stand under the engine to raise the
front wheel off the ground. Hold the
lower end of the front forks and try to
move them forward and backward. If
any free play can be felt, ask a Yamaha
dealer to inspect and adjust the steer-
ing. Inspection is easier if the front
wheel is removed.

WARNING
@ Securely support the motorcycle so
there is no danger of it falling over. @
EAU00800
BatteryThis motorcycle is equipped with a
sealed-type battery. Therefore it is not
necessary to check the electrolyte or fill
the battery with distilled water.l
If the battery seems to have dis-
charged, consult a Yamaha deal-
er.
l
If the motorcycle is equipped with
optional electrical accessories, the
battery tends to discharge more
quickly, so be sure to recharge it
periodically.

CAUTION:@ Never try to remove the sealing caps
of the battery cells. The battery will
be damaged. @

8-MOTORCYCLE CARE AND STORAGECareThe exposure of its technology makes
a motorcycle charming but also vulner-
able. Although high-quality compo-
nents are used, they are not all rust-re-
sistant. While a rusty exhaust pipe may
remain unnoticed on a car, it does look
unattractive on a motorcycle. Frequent
and proper care, however, will keep
your motorcycle looking good, extend
its life and maintain its performance.
Moreover, the warranty states that the
vehicle must be properly taken care of.
For all these reasons, it is recommend-
ed that you observe the following
cleaning and storing precautions.Before cleaning
1. Cover up the muffler outlets with
plastic bags.
2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug caps, are tightly in-
stalled.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.Cleaning
After normal use
Remove dirt with warm water, a neutral
detergent and a soft clean sponge,
then rinse with plenty of clean water.
Use a tooth or bottle brush for hard-to-
reach parts. Tougher dirt and insects
will come off more easily if the area is
covered with a wet cloth for a few min-
utes before cleaning.
