9Tire information
This motorcycle is equipped with cast
wheels and tubeless tires with valves.
WARNING
EWA10900
The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle cannot be guaranteed.
After extensive tests, only the
tires listed below have been ap-
proved for this model by
Yamaha Motor Co., Ltd.
Always make sure that the valvecaps are securely installed to
prevent air pressure leakage.
Use only the tire valves and
valve cores listed below to
avoid tire deflation during a ride.
WARNING
EWA10600
This motorcycle is fitted with su-
per-high-speed tires. Note the fol-
lowing points in order to make themost efficient use of these tires.
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.
Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.
The tires must be warmed up
before a high-speed run.
Always adjust the tire air pres-
sure according to the operating
conditions.
