Use only the specified tires. (See
page 6-15.) Using different sized
tires will prevent the traction control
system from controlling tire rotationaccurately.
Resetting the traction control sys-
tem
The traction control system will auto-
matically disable when:
the front wheel or rear wheel
comes off the ground while riding.
excessive rear wheel spin is de-
tected while riding.

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 spec
ialists to ascertain
their suitability for further use.
WARNING
EWA10902
The front and rear tires should
be of the same make and de- sign, otherwise the handling
characteristics of the motorcy-
cle may be different, which
could lead to an accident.
Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
Use only the tire valves and
valve cores listed below toavoid tire deflation during a ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha.
WARNING
EWA10601
This motorcycle is fitted with su-
per-high-speed tires. Note the fol-
lowing points in order to make the
most 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 operatingconditions.
