WARNING
EWA10481
● 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 a
high-speed ride.
After extensive tests, only the tires list-
ed below have been approved for this
model by Yamaha Motor Co., Ltd.
WARNING
EWA10600
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 operating
conditions.
