cracked, have a Yamaha dealer
replace the tire immediately.

WARNING
It is dangerous to ride with a
worn-out tire. When a tire tread
begins to show crosswise lines,
have a Yamaha dealer replace
the tire immediately.
The replacement of all wheel
and brake related
including the tires, should be
left to a Yamaha dealer, who has
the necessary professional
knowledge and experience to do
so.
Ride at moderate speeds after
changing a tire since the tire
surface must first be "broken in"
for it to develop its optimal
characteristics.
