Tire inspection
1. Tire sidewall
2. Tire wear indicator
3. Tire tread depth
The tires must be checked before each
ride. 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, contact a
Yamaha dealer immediately and have
the tire replaced.
Minimum tire tread depth (front and
rear):
1.0 mm (0.04 in)
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. Brakes,
tires and related wheel parts re-
placement should also be left to
a Yamaha dealer.
 Ride at moderate speeds after
EWA10512
changing a tire since the tire
surface must first be "broken
in" for it to develop its optimal
characteristics.
Tire information
This model is equipped with tubeless
tires and tire air valves.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
WARNING
The front and rear tires should be of
the same make and design, other-
wise the handling characteristics of
the vehicle may be different, which
could lead to an accident.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.
