WARNING
Check the wear of the brake pads especially before every trip.
To carry on a quick check of the brake pad
wear:
♦ Position the vehicle on the central stand.
♦ Carry on a visual check between the brake
disk and the pads, proceeding:
FRONT BRAKE CALLIPER
– On the front, part from below, for both cal-
lipers.
REAR BRAKE CALLIPER
– On the rear part, from below, for both pads
(C).
WARNING
The excessive wear of the friction material would cause the contacts of the pad
metal support with the disk, with consequent metallic noise and production of
sparks from the calliper; braking efficiency, safety and soundness of the disk
would be compromised.
♦ If the thickness of the friction material (even
if of one pad only) has reduced to about
1.5 mm, have both pads replaced.
– Front pads (2).
– Rear pads (3).
WARNING
Have the pads replaced by your aprilia
Official Dealer.

The stand (4) must rotate without hindrances.
Carry on the following checks:
♦ The springs (5) must not be damaged,
worn, rusty or weakened.
♦ The stand must rotate without hindrances;
if necessary, grease the joint (see page 74
TABLE OF LUBRICANTS).
CHECKING THE SWITCHES
The vehicle is provided with two switches:
- Stoplight switch on the rear brake control
lever (combined)
- Stoplight switch on the front brake control
lever.
If you need assistance or technical advice,
contact your aprilia Official Dealer, who can
ensure you an accurate and prompt service.
To replace the front suspension oil con-
CAUTION
tact your aprilia Official Dealer, who can
ensure you an accurate and prompt service.
Have the front suspension oil changed every
30000 km (18750 miles) or every 4 years.
Carry on the following checks after the first
1000 km (625 miles) and successively after
6000 km (3750 miles):
♦ With pulled front brake lever, push the fork
repeatedly downwards. The stroke must be
smooth and there must not be any trace of
oil on the rods.
♦ Make sure that all components are fas-
tened and that the front and rear suspension joints work correctly.
CAUTION
Should you notice irregularities in the
operation or if the help of skilled personnel should be necessary, contact your
aprilia Official Dealer.

ADJUSTING THE REAR SUSPENSION
The rear suspension consists of a pair of
double-action shock absorbers (braking with
compressed/extended shock absorber) fastened to the engine by means of silentblocks.
The standard adjustment, set by the manufacturer, is suitable for a driver weighing
about 70 kg. In case of different weights or
needs, adjust the ring nut (1) by means of
the appropriate spanner provided in the tool
kit, thus setting the ideal drive conditions (see
table).
CAUTION
Set both shock absorbers on the same
position.

CHECKING THE STEERING
Carefully read page 40 (MAINTENANCE).
It is necessary to check the steering slack
occasionally.
To carry on the check:
♦ Position the vehicle on the central stand.
IMPORTANT Provide for a support with
height and rest surface suitable to support
the vehicle safely.
♦ Place the support under the vehicle and a
spongy cloth between them, so that the
front wheel can move freely and the vehicle cannot fall down.

Make sure that the vehicle is stable.
♦ Shake the fork in the riding direction.
CAUTION
If you shake the fork excessively, the
stand will move, thus producing an incorrect slack. Repeat the previous operation
more than once.
♦ If the slack is considerable, contact your
aprilia Official Dealer, who will restore the
optimal operating conditions.

CAUTION
STEERING SHOCK ABSORBER
Carefully read page 40 (MAINTENANCE).
In case of full load trips (driver + passenger
+ luggage), it is possible to adjust the steering shock absorber.
To adjust the steering shock absorber:
♦ If you rotate the ring nut (1) clockwise, the
shock absorber becomes more rigid.
CAUTION
If you tighten the ring nut, the shock absorber becomes more rigid and consequently the effort to be made to rotate the
handlebar increases, thus reducing the
manoeuvrability.
CHECKING THE ENGINE FULCRUM
AXIS
Carefully read page 40 (MAINTENANCE).
Periodically check the slack between the
engine pin bushes.
To carry on the check:
♦ Position the vehicle on the central stand.
♦ Shake the wheel transversally with respect
to the riding direction.
♦ If you notice some slack, contact your
aprilia Official Dealer, who will restore the
optimal operating conditions.
