Wheels
To maximize the performance, durabil-
ity, and safe operation of your motorcy-
cle, note the following points regarding
the specified wheels.
●
The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness (for
spoke wheel model) 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.

Checking the brake lever free
play
There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.

WARNING
_
A soft or spongy feeling in the brake
lever can indicate the presence of
air in the hydraulic system. If there
is air in the hydraulic system, have a
Yamaha dealer bleed the system be-
fore operating the vehicle. Air in the
hydraulic system will diminish the
braking performance, which may re-
sult in loss of control and an acci-
dent.
