MODELS UP TO
2.31.1 REAR SUSPENSION
The rear suspension consists of a spring-shock absorber
unit, fixed to the frame by means of a uni-ball and to the
rear fork by means of lever systems.
For the setting of the vehicle attitude, the shock absorber
is provided with a screw adjuster (1) for the adjustment of
the hydraulic braking with extended shock absorber; a
knob adjuster (2) for the adjustment of the hydraulic brak-
ing with compressed shock absorber; a ring nut for the
adjustment of the spring preload (3) and a locking ring nut
(4).
The riding position of the vehicle can be further altered by
varying the height of the rear axle by adjusting the lock
nut (5) and adjuster nut (6).
Carefully read 0.5.1 (PRECAUTIONS AND GENERAL
INFORMATIONS).
Rear shock absorber:
for the maintenance intervals, see 2.1.1 (REGULAR
SERVICE INTERVALS CHART).
◆
Check all the rear suspension joints are working prop-
erly and that the relevant components are properly
tightened.
2.31.2 ADJUSTING THE REAR SHOCK ABSORBER
The standard setting of the rear shock absorber is such
as to satisfy most driving conditions at low and high
speed, either with reduced load and full load.
However, it is possible to adjust the setting according to
how the vehicle is going to be used.
a
CAUTION
For the adjustment, always start from the most rigid
setting; screw adjuster (1) and knob adjuster (2) com-
pletely rotated clockwise.
Do not rotate the screw adjuster (1) beyond its limit
position, to avoid damaging the thread.
Make sure that the screw adjuster (1) always snaps
and is not in any intermediate position.
◆
Slightly unscrew the locking ring nut (4) by means of
the appropriate spanner.
◆
Act on the adjusting ring nut (3) (shock absorber spring
preload adjustment) (see figure).
◆
After the adjustment, tighten the metal ring (4).
◆
Adjust the hydraulic braking with extended shock ab-
sorber by means of the screw (1) (see table).
◆
Adjust the knob (2) to adjust the hydraulic braking with
compressed shock absorber (see table).
To vary the attitude of the vehicle, proceed as follows:
◆
Moderately loosen the lock nut (5).
NOTE
Rotate the adjuster (6) by giving it one turn at a
time, so that the adjusting screw (1) is always on the left
side of the vehicle.
◆
Act on the adjuster (6) (see table).
a
CAUTION
The lock nut (5) must be tightened with the indicated
driving torque.
◆
After the adjustment, tighten the lock nut (5).
Lock nut (5) driving torque: 40 Nm (4.0 kgm).
