ADJUSTING THE REAR SUSPENSION
(Fig. 59)
The rear suspension comprises a single spring-
shock absorber unit and a lever unit with A.P.S.
The standard rear suspension is suitable for a driver
weighing about 75 kg.
In case your weight or riding style are different from
the standard setting, change shock absorber spring
length by turning ring nut (4) and (5) or rebound adju-
ster by turning knob (1).
Rebound adjuster standard setting: 8 Ø 1 clicks from
the fully closed position.
To check this position:
With the vehicle in an upright position, without the
◆
rider and prop stand, measure the distance (2-3).
With the rider sitting in the riding position (feet on
◆
the footpegs) and the vehicle in vertical position,
measure the distance (2-3) again.
The difference between the two measures (shock
◆
absrober pre-loading) must be included between
a maximum of 100 mm and a minimum of
90 mm.
To adjust spring (A) pre-load, loosen check ring nut
(4) and adjust ring nut (5).
Standard setting: 212 mm.
Max. pre-load setting: 207 mm.
