Tire inspection
1. Tire sidewall
2. Tire wear indicator
3. Tire tread depth
The tires must be checked before each
ride. If the 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, have a Yamaha
dealer replace the tire immediately.
Minimum tire tread depth (front and
rear):
1.0 mm (0.04 in)
Periodic maintenance and adjustment
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 parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
 It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.
 Ride at moderate speeds after
changing a tire since the tire
surface must first be "broken
in" for it to develop its optimal
characteristics.
Tire information
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
7-17
rubber, sometimes accompanied by
EWA10563
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
For cast wheel models:
This model is equipped with tubeless
tires and rubber tire air valves.
For spoke wheel models:
This model is equipped with tube tires.
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 by
Yamaha.
