Periodically check the tyre inflation pres-
a
sure at room temperature. If the tyres are
hot, the measurement is not correct.
Carry out the measurement especially after long
rides.
If the inflation pressure is too high, the ground
unevenness cannot be dampened and is there-
fore transmitted to the handlebar, thus compro-
mising the driving comfort and reducing the road
holding during turns.
If, on the contrary, the inflation pressure is too
low, the tyre sides are under greater stress and
the tyre itself may slip on the rim or it may be-
come loose, with consequent loss of control of
the vehicle.
In case of sudden braking the tyres could even
get out of the rims. Further, the vehicle could
skid while turning.
Check the surface and the wear of the tyres,
since tyres in bad conditions can impair both the
grip and the controllability of the vehicle.
Change the tyre when it is worn out or in case of
puncture on the tread side, if the puncture is larg-
er than 5 mm.
Use only tyres in the size suggested by
see p. 79 (TECHNICAL DATA).

Do not install tyres with air tube on rims for tube-
less tyres and viceversa.
Make sure that the tyres always have their valve
sealing caps on, to prevent them from suddenly
going flat.
Change, reparation, maintenance and balancing
operations are very important and should be car-
ried out by qualified technicians with appropriate
tools.
For this reason, it is advisable to have the above
mentioned operations carried out by an
Official Dealer or by a qualified tyre repairer.
If the tyres are new, they may still be cov-
a
ered with a slippery film: drive carefully
for the first miles.
Do not oil the tyres with unsuitable fluids.
