After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.
WARNING
EWA15542
Have a Yamaha dealer 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-related parts, includ-
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 prod uct.
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
To maximize the performance, durabil-
ity, and safe operation of the vehicle,
note the following points.
Check each wheel for cracks, de-
formation and other damage. If
any damage is found, have the
wheel inspected by your Yamaha
dealer. Do not attempt to repair or
straighten a bent or damaged
wheel.
Check the spokes for looseness. If
any loose spokes are found, have
the wheel adjusted by your
Yamaha dealer. Improperly tight- ened spokes can cause wheel
misalignment.
Have the wheel balanced whenev-
er the tire or tube has been re-
placed. An unbalanced wheel can
result in adverse handling charac-
teristics and shortened tire life.
WARNING

d esi gne d for use with tu beless tires.
Do not attempt to use tu beless tires
