Always check the tires before operating
the motorcycle. If a tire tread shows
crosswise lines (minimum tread depth),
if the tire has a nail or glass fragments
in it, or if the sidewall is cracked, con-
tact a Yamaha dealer immediately and
have the tire replaced.
Minimum tire tread depth (front and
rear):
1.0 mm (0.04 in)
PERIODIC MAINTENANCE AND ADJUSTMENT
WARNING
G 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.
G The replacement of all wheel-
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience to do so.
G
Ride at moderate speeds after
changing a tire since the tire
surface must first be "broken
in" for it to develop its optimal
characteristics.
