CHECKING THE BRAKE PAD WEAR
(Fig. 17-18)
Check the brake pad wear every 2000 km. In order to
check this properly, it is necessary to remove the cal-
iper from the support by unscrewing the screws (1).
The pads present a groove that must always be visi-
ble.
If this groove is not visible any more (thickness of
the friction surface = 1,5 mm), change the pads.
CHANGING THE FORK OIL (Fig. 19)
It is advisable to have this operation per-
formed by an aprilia Official Dealer, who
will ensure qualified and prompt servic-
ing.
The fork oil must be changed every 12000 km, or
more frequently if the vehicle is used off-road.
To carry out this operation it is necessary to remove
the front wheel and to withdraw the two fork tube as-
semblies from the plates.
Right fork tube assembly:
ā Unscrew and remove the upper plug of the slider
(see figure) and slightly press the slider itself
downwards until the two half-washers can be re-
moved.
