◆
Make sure that the level of the fluid con-
tained in the expansion tank (1) is inclu-
ded between the “
MIN
” and “
MAX
”
marks (see figure).
◆
If not, unscrew and remove the filling
plug (2).
◆
Top up the expansion tank by adding co-
o la nt, see pag e 81 (L U BR I C AN T
CHART), until this almost reaches the
“
MAX
” level. Do not exceed this level,
otherwise the coolant will flow out while
the engine is running.
◆
Put back the filling plug (2).
In case of excessive consump-
tion of coolant and in case the
tank remains empty, make sure
that there are no leaks in the circuit.
Have it repaired by an Concessionario

TYRES
This vehicle is provided with tubeless tyres.
Periodically check the tyre infla-
tion pressure at room tempera-
ture, see page 78 (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 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 page 78
(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 bal-
ancing 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 care-
fully for the first miles. Do not oil the
tyres with unsuitable fluids.
If the tyres are old, even if not complete-
ly worn out, they may become hard and
may not ensure good road holding.
In this case, replace them.
