WARNING
EWA10882
Gasoline an d g asoline vapors are
extremely flamma ble. To avoi d fires
an d explosions an d to re duce the
risk of injury when refuelin g, follow
these instructions.1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. Stop filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank.

WARNING
EWA10611
The wheels on this mo del are not
d esi gne d for use with tu beless tires.
Do not attempt to use tu beless tires
on this mod el.To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified wheels.
The wheel rims should be
checked for cracks, bends, warp-
age or other damage, and the
spokes for looseness or damage
before each ride. If any damage is
found, have a Yamaha dealer re-

poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
