WARNING

 

EWA10610

 

The wheels on this model are not de-
signed for use with tubeless tires.
Do not attempt to use tubeless tires

 

on this model.

 

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, warpage or
damage 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.

 

●

 

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.

 

●

 

Ride conservatively after changing

a tire since the tire must seat itself
on the rim properly. Failure to al-
low proper seating may cause tire
failure, which may result in dam-
age to the motorcycle and injury to
the rider.
