Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimalcharacteristics.
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 should be checked by tire specialists to ascertain
their suitability for further use.
WARNING
EWA10482

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 to
avoid tire deflation during ahigh-speed ride.
After extensive tests, only the tires list-
ed below are 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

Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.

Checking and lubricating the
cablesThe operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe condi-
tions.
[EWA10712] EAU23115
Checking and lubricating the
throttle grip and cableThe operation of the throttle grip should
be checked before each ride. In addi-
tion, the cable should be lubricated by a
Yamaha dealer at the intervals speci-
fied in the periodic maintenance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from water
entry. Therefore, use care not to pour
water directly onto the cover or cable
when washing the vehicle. If the cable
or cover becomes dirty, wipe clean with
a moist cloth.
EAU44276
Checking and lubricating the
brake and shift pedalsThe operation of the brake and shift
pedals should be checked before each
ride, and the pedal pivots should be lu-
bricated if necessary.
