PERIODIC MAINTENANCE AND MINOR REPAIR
EAU21960
Cast wheelsTo maximize the performance, durability,
and safe operation of your motorcycle,
note the following points regarding the
specified wheels.l
The wheel rims should be checked
for cracks, bends or warpage 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.
l
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 handling
characteristics, and a shortened
tire life.
l
Ride at moderate speeds after
changing a tire since the tire surface
must first be “broken in” for it to
develop its optimal characteristics.
