ADJUSTING
THE REAR SUSPENSION
The rear suspension is constituted by a
pair of double-action shock absorbers
(braking with compressed/extended shock
absorber) fixed to the engine by means of
silent-blocks.
The shock absorbers are provided with a
metal ring with five positions, for the
adjustment of the spring preload. The
s t a n d a r d a d j u s t m e n t , s e t b y t h e
manufacturer, is suitable for a driver
weighing about 70 kg.
If your weight and needs are different,
adjust the ring nut (1) with the appropriate
spanner provided in the tool kit, thus
setting the ideal travelling conditions (see
table).
!
CAUTION
Set both shock absorbers on the same
position.
!
CAUTION
Before adjusting the spring preload,
verify what type of shock absorber is
installed on the vehicle:
- upper adjustment;
- lower adjustment.
