To check the final gear oil level
1. Place the motorcycle on a level sur-
face and hold it in an upright position.
NOTE:
•The final gear oil level must be
checked on a cold engine.
•Make sure that the motorcycle is posi-
tioned straight up when checking the
oil level. A slight tilt to the side can
result in a false reading.2. Remove the oil filler bolt, and then
check the oil level in the final gear
case.
NOTE:
The oil level should be at the brim of the
filler hole.
3. If the oil is below the brim of the filler
hole, add sufficient oil of the recom-
mended type to raise it to the correct
level.
To change the final gear oil
1. Place an oil pan under the final gear
case to collect the used oil.
2. Remove the oil filler bolt and drain
bolt to drain the oil from the final gear
case.

Final gear oil
The final gear case must be checked for oil
leakage before each ride. If any leakage is
found, have a Yamaha dealer check and
repair the motorcycle. In addition, the final
gear oil level must be checked and the oil
changed as follows at the intervals speci-
fied in the periodic maintenance and lubri-
cation chart.

•Make sure that no foreign material
enters the final gear case.
• Make sure that no oil gets on the
tire or wheel.

NOTE:
The tire tread depth limits may differ from
country to country. Always comply with the
local regulations.
EW000079WARNING0
•Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the motor-
cycle with excessively worn tires
decreases riding stability and can
lead to loss of control.
•The replacement of all wheel- and
brake-related parts, including the
tires, should be left to a Yamaha
dealer, who has the necessary pro-
fessional knowledge and experi-
ence.
Tire information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
EW000080WARNING0
•The front and rear tires should be
of the same make and design, oth-
erwise the handling characteris-
tics of the motorcycle cannot be
guaranteed.
•After extensive tests, only the tires
listed below have been approved
for this model by Yamaha Motor
Co., Ltd.
•Always make sure that the valve
caps are securely installed to pre-
vent air pressure leakage.
•Use only the tire valves and valve
cores listed below to avoid tire
deflation during a high-speed ride.

Tire inspection
The tires must be checked before each ride.
If the center tread depth reaches the speci-
fied limit, if the tire has a nail or glass frag-
ments in it, or if the sidewall is cracked,

EAU00684WARNING0
•This motorcycle is fitted with
super-high-speed tires. Note the
following points in order to make
the most efficient use of these
tires.
•Use only the specified replace-
ment tires. Other tires may run the
danger of bursting at super high
speeds.
•Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”.
•Therefore, it is advisable before
doing any high-speed riding to
ride conservatively for approxi-
mately 100 km (60 mi) after
installing a new tire.
•The tires must be warmed up
before a high-speed run.
•Always adjust the tire air pressure
according to the operating condi-
tions.
EAU03773
Cast wheels
To maximize the performance, durability,
and safe operation of your motorcycle,
note the following points regarding the
specified wheels.
The wheel rims should be checked for
cracks, bends or warpage before each
ride. If any damage is found, have a Yama-
ha dealer replace the wheel. Do not at-
tempt even the smallest repair to the
wheel. A deformed or cracked wheel must
be replaced.
The wheel should be balanced whenever
either the tire or wheel has been changed
or replaced. An unbalanced wheel can re-
sult in poor performance, adverse han-
dling characteristics, and a shortened tire
life.
