REAR SUSPENSION

The rear suspension consists of a spring-
shock absorber unit, fixed to the frame by
means of silent-blocks and to the rear fork
by means of lever systems. For the setting
of the vehicle attitude, the shock absorber
is provided with a nut (1) for the adjustment
of the spring preload (2).
It is possible to adjust the shock
absorber axis distance to per-
sonalize the vehicle attitude.
For this kind of adjustment, contact an
Concessionario Ufficiale aprilia.
ADJUSTING
THE REAR SHOCK ABSORBER
The standard setting of the rear shock ab-
sorber is such as to satisfy most driving
conditions at low and high speed, either
with reduced load and full load.
However, it is also possible to adjust the
setting according to the intended use of the
vehicle.
The adjusting nut must not be
screwed for more than 25 mm
from the beginning of the thread
(see figure). If this measure is exceed-
ed, even the slightest unevenness on
the road surface will cause sudden
jerks.
N Act on the adjusting nut (1) (shock ab-
sorber spring preload adjustment) (see
figure).
Turn the adjusting nut (1) one
turn at a time.
Test the vehicle repeatedly on
the road, until obtaining the optimal ad-
justment.
