WARNING
● 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 conserva-
tively 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.
