WARNING
EWA10601
This motorcycle is fitted with super-
high-speed tires. Note the following
points in order to make the most ef-
ficient 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 rel-
atively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any high-
speed riding to ride conserva-
tively for approximately 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 pres-
sure according to the operating
conditions.

Cast magnesium wheels
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding these wheels.
The wheel rims should be
checked for cracks, bends, warp-
age or damage before each ride. If
any damage is found, have a
Yamaha dealer replace the wheel.
Do not attempt even the smallest
repair to the wheel. A deformed or
cracked wheel must be replaced.
The wheel should be balanced
whenever the tire or wheel has
been changed or replaced. An un-
balanced wheel can result in poor
performance, adverse handling
characteristics, and shortened tire
life.
These wheels are made of magnesium
and require special care.
When balancing the wheel, use
press-on type weights to avoid
scratching the wheel.
