TYRES
This vehicle is provided with tubeless tyres.
WARNING
Periodically check the tyre inflation
pressure 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
g r o u n d u n e v e n n e s s c a n n o t b e
dampened and is therefore transmitted
to the handlebar, thus compromising
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 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
i m p a i r b o t h t h e g r i p a n d t h e
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.
After repairing a tyre, have the wheels
balanced. Use only tyres in the size
s u g g e s t e d b y a p r i l i a , s e e p . 7 3
(TECHNICAL DATA).
Make sure that the tyres always have
their valve sealing caps on, to prevent
them from suddenly going flat.
Change, repair, 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 fluids.
I f t h e t y r e s a r e o l d , e v e n i f n o t
completely worn out, they may become
hard and may not ensure good road
holding.
In this case, replace them.

CATALYTIC SILENCER
# ;
WARNING
Avoid parking the vehicle catalytic
version near dry brush wood or in
places easily accessible to children, as
t h e c a t a l y t i c s i l e n c e r b e c o m e s
extremely hot during use; be very
careful and avoid any kind of contact
before it has completely cooled down.
The catalytic vehicle is fitted with a silencer
with metal catalytic converter of the
≈ platinum-rhodium bivalent ∆ type.
This device provides for the oxidation of
the CO (carbon monoxide) and of the HC
(unburned hydrocarbons) contained in the
exhaust gases, changing them into carbon
dioxide and steam, respectively.
CAUTION
Do not use leaded petrol, since it
causes the destruction of the catalytic
converter.
