TYRES
This vehicle is provided with tubeless tyres.
Periodically check the tyre inflation pres-
sure at room temperature, see p. 73
(TECHNICAL DATA).
If the tyres are hot, the measurement is
not correct. Carry out the measurement
especially before and after long rides.
If the inflation pressure is too high, the
ground unevenness cannot be dampened
and is therefore transmitted to the han-
dlebar, thus compromising the driving
comfort and reducing road holding dur-
ing turns.
If, on the contrary, the inflation pressure
is too low, the tyre sides (1) are under
greater stress and the tyre itself may slip
on the rim or it may become loose, with
consequent loss of control of the vehi-
cle.
In case of sudden braking the tyres could
even get out of the rims. Further, the ve-
hicle 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 controllabil-
ity of the vehicle.
Some types of tyres homologated for this
vehicle are provided with wear indicators.
There are several kinds of wear indica-
tors.
For more information on how to check the
wear, contact your Dealer.
Visually check if the tyres are worn and
in this case have them changed.
If the tyres are old, even if not completely
worn out, they may become hard and may
not ensure good road holding.
In this case, have the tyres changed.
Change the tyre when it is worn out or in
case of puncture on the tread side, if the
puncture is larger than 5 mm.
After repairing a tyre, have the wheels bal-
anced.
The tyres must be replaced with other
tyres of the type and model recommended
by the manufacturer, see p. 73 (TECHNI-
CAL DATA); the use of tyres different from
those prescribed may adversely affect the
manoeuvrability of the vehicle.
Do not install tyres with air tube on rims
for tubeless tyres and viceversa.
