This vehicle is provided with tubeless
tyres.
Periodically check the tyre infla-
tion pressure at room tempera-
ture.
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 damp-
ened and is therefore transmitted to the
handlebar, thus compromising the driv-
ing comfort and reducing the road hold-
ing 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 become 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 controlla-
bility of the vehicle.
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
balanced.
Use only tyres in the size suggested by
APRILIA, see p. 59 (TECHNICAL DATA).
Do not install tyres with air tube on rims
for tubeless 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 carried out by qualified
technicians with appropriate tools.
For this reason, it is advisable to have
the above mentioned operations carried
out by an APRILIA Official Dealer or by a
qualified tyre repairer.
If the tyres are new, they may
still be covered with a slippery
film: drive carefully for the first
miles.
Do not oil the tyres with unsuitable flu-
ids.
