WARNING
EWA15542
Have a Yamaha d ealer replace
excessively worn tires. Operat-
in g the motorcycle with exces-
sively worn tires decreases
ri din g sta bility an d can lead to
loss of control.
The replacement of all wheel-
and b rake-relate d parts, inclu d-
in g the tires, shoul d b e left to a
Yamaha dealer, who has the
necessary professional knowl-
e dge an d experience.
It is not recommen ded to patch
a puncture d tu be. If unavoid -
a b le, however, patch the tu be very carefully an
d replace it as
soon as possi ble with a hi gh-
quality pro duct.
Ride conservatively after
chan gin g a tire since the tire
must seat itself on the rim prop-
erly. Failure to allow proper
seatin g may cause tire failure,
which may result in damag e to
the motorcycle an d injury to the
ri der.

Spoke wheels
WARNING
EWA10611
The wheels on this mod el are not
d esi gne d for use with tu beless tires.
Do not attempt to use tu beless tires
on this mo del.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-
place 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 either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
