ISPEZIONE RUOTE
• Make sure that the wheel rims are neither cracked, nor
deformed. Change them if necessary.
• Check the wheel balancing. Make the wheel rotate
several times and observe the point on which it stops.
If the wheel is not statically balanced, it will always stop
on the same point. Put a balancing weight on the lightest
(highest) point.
TYRESÙ
This vehicle is provided with tubeless tyres.
WARNING
Periodically check the tyre inflation pressure at
room temperature (once a month). If the tyres
are hot, the measurement is not correct. The
pressure must be measured with the tyres at
room temperature, that is, when the vehicle has
not covered more than 1 km (0.621 mi) in the
last 2 or 3 hours. Check the tread depth often
and if this is worn beyond the allowed limit (2
mm) (0.079 in), change the tyre. Swelling and
waves indicate that there are internal damages,
therefore the tyre must be immediately replaced.
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
larger than 5 mm (0.197 in).
After repairing a tyre, have the wheels balanced.
Use only tyres in the size suggested by
aprilia. 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. 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
fluids.
