Tyres

1. Wheel marking
This motorcycle is equipped with tubeless
tyres, valves and wheel rims. Use only tyres
marked 'TUBELESS' and tubeless valves on
rims marked 'SUITABLE FOR TUBELESS
TYRES' .
Tyre Inflation Pressures
Correct inflation pressure will provide
maximum stability, rider comfort and tyre life.
Always check tyre pressures before riding
when the tyres are cold. Check tyre
pressures daily and adjust if necessary. See
the Specification section for details of the
correct inflation pressures.
Tyre Wear
As the tyre tread wears down, the tyre
becomes more susceptible to punctures and
failure. It is estimated that 90% of all tyre
problems occur during the last 10% of tread
life (90% worn). It is therefore not
recommended to use tyres until they are
worn to their minimum.

Warning
Incorrect tyre inflation will cause abnormal
tread wear and instability problems that
may lead to loss of control and an accident.
Under-inflation may result in the tyre
slipping on, or coming off the rim.
Over-inflation will cause instability and
accelerated tread wear.
Both conditions are dangerous as they may
cause loss of control leading to an accident.
