Cast wheelsWheelsTo maximize the performance, dura-
bility, and safe operation of your
scooter, note the following points
regarding the specified wheels.
8The 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.
8The 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.

and brake related parts,

al knowledge and experience.
