♦Position the vehicle on the centre stand,
on a solid and level surface.
NOTE Arrange for a support with a base
of 200x200mm and suitable height.
♦Place the support under the vehicle and a
spongy cloth between them, so that the
front wheel can move freely and the vehi-
cle cannot fall down.
Make sure that the vehicle is stable.
♦Put a suitable support (1) under the tyre to
hold the wheel in the right position, after
releasing it.
♦Unloose screw (2) of the wheel pin clamp.
♦Completely unscrew the wheel pin (3).
Wheel pin-nut driving torque:
50 Nm (5.0 kgm).
♦Hold the front wheel and manually remove
the wheel pin (3).
♦Keep the washer (4).
Do not actuate the front brake lever after
removing the wheel to prevent the caliper
pistons from falling out of their seats,
causing the brake fluid to leak out.
In this case, contact an aprilia Official
Dealer that will carry out the required
maintenance operations.
♦Move the front wheel forward until the disc
can be removed from the brake caliper (5).
♦Remove the front wheel.
♦Disable the odometer transmission (6).

Contact an aprilia Official Dealer if nec-
essary.
If you wish to perform this operation per-
sonally, follow the steps below.

REASSEMBLY
Carefully read page 47 (MAINTENANCE).
While reassembling the wheel, be careful
not to damage the brake pipe, the disc
and the pads.
To reassemble the front wheel, proceed as
follows:
♦Smear a thin layer of grease on the whole
length of the wheel pin (3), see page 90
(LUBRICANT CHART).
♦Position the wheel between the fork rods,
onto the support (1).
♦Insert the tang (8) of the odometer trans-
mission (7) in the seat on the wheel hub.
Risk of personal injury. Do not use your
fingers to align the holes.
♦Move the wheel to align the central hole
with the holes on the fork.
♦Make sure that the following components
are not dirty:
– tyre;
– wheel;
– brake discs.
After reassembly, pull the front brake le-
verrepeatedlyandcheckthecorrectfunc-
tioning of the braking system.
Check the wheel centering.
Have the driving torques, centering and
balancing of the wheel checked by your
aprilia Official Dealer, in order to avoid
accidents that may be harmful for you
and/or other people.
CAUTION
WARNING
♦Insert the wheel between the rods. Insert
with care the disc in the brake caliper.
♦Insert the washer (4) between the
odometer transmission (7) and the fork
right-hand rod.
♦Fully insert the wheel pin (3) and tighten it
manually.
♦Tighten the wheel pin (3).
Wheel pin nut driving torque:
50 Nm (5.0 kgm).
♦Pull the front brake lever and repeatedly
push down the handlebar to allow the fork
to sink.
This allows the fork rods to bed properly.
♦Tighten the screw (2) of the wheel pin
clamp.
Driving torque of the wheel pin clamp
screws: 12 Nm (1.2 kgm).

REAR WHEEL
DISASSEMBLY
The disassembly and reassembly opera-
tions of the rear wheel may result diffi-
cult and complicated for an unskilled op-
erator. Contact an aprilia Official Dealer
if necessary.
If you wish to perform this operation per-
sonally, follow the steps below.
Carefully read page 47 (MAINTENANCE).
Before performing the following opera-
tions, allow the engine and silencer to
cool down to the ambient temperature in
order to avoid burns.
On disassembly and reassembly of
the wheel, be careful not to damage the
pipeline, disc and brake pads.
♦Position the vehicle on the centre stand,
on a solid and level surface.
♦Remove the silencer, see page 66 (RE-
MOVING THE EXHAUST SILENCER).
♦Remove the cover (1).
♦Withdraw the wheel.
NOTE Use aprilia Genuine Spare Parts
only.
♦After reassembly, make sure that the fol-
lowing components are not dirty:
– tyre;
– wheel;
–brake discs.
After reassembly, pull the rear brake le-
ver repeatedly and check the correct func-
tioning of the braking system. Check the
wheel centering.
Have the driving torques, centering and
balancing of the wheel checked by your
aprilia Official Dealer, in order to avoid
accidentsthatmaybeharmfulforyouand/
or other people.
CAUTION
NOTETo be able to unloose the wheel nut
(2) it is necessary to block the wheel.

CHECKING THE BRAKE PAD
WEAR
Carefully read page 31 (BRAKE FLUID -
recommendations), page 32 (DISC
BRAKES), page 47 (MAINTENANCE).
Check the brake pad wear after the first 500
km (312 mi) and successively every 2000
km (1250 mi).
The wear of the brake pads depends on the
use, on the kind of drive and on the road.
The wear will be greater when the vehicle is
driven on dirty or wet roads.
Check the wear of the brake pads espe-
cially before every trip.
To carry out a rapid checking of the wear of
the front pads, proceed as follows:
♦Position the vehicle on the centre stand,
on a solid and level surface.
♦Remove the brake caliper cover (1).
♦Carry out a visual check between brake
disc and pads.
The excessive wear of the friction mate-
rial would cause the contact of the pad
metal support with the disc, with conse-
quent metallic noise and production of
sparks from the caliper; braking effi-
ciency, safety and soundness of the disc
would thus be negatively affected.
♦Ifthethicknessofthe friction material (even
of one pad only) has reduced to about 1.5
mm, replace both pads.
Have the pads changed by your aprilia
Official Dealer.
