SUSPENSIONS
Fork
Adjusting the rebound damping
The hydraulic rebound damping unit determines the behaviour
of the fork during the rebound phase and is adjusted by means
of screw A. Turning the screw clockwise (towards the + sign) or
anticlockwise (towards the – sign) respectively increases or de-
creases the rebound damping.
Standard adjustment:
12 clicks from the completely closed position
Adjusting the compression damping
The hydraulic compression damping unit determines the behav-
iour of the fork during the compression phase and can be ad-
justed by means of screw B at the lower end of the fork legs.
Turning the screw clockwise or anticlockwise respectively in-
creases or decreases the compression damping.
Standard adjustment:
12 clicks from the completely closed position
Shock absorber
Adjusting the hydraulic compression damping
(high/low speeds)
The shock absorber can be adjusted for both high and low
speeds.
The expressions ‘high speed’ and ‘low speed’ refer to the move-
ment of the shock absorber, not to the speed of the vehicle.
The low and high speed adjustments affect the behaviour of the
shock absorber during slow and fast compression respectively.
Low speed adjustment:
– Using a screwdriver, turn screw C clockwise to decrease the
hydraulic compression damping.
Standard adjustment:
completely open screw, 21/21 clicks
High speed adjustment:
– Turn knob D anticlockwise to decrease the hydraulic com-
pression damping.
Standard adjustment:
completely open knob, 24/24 clicks
WARNING: If the knob is turned anticlockwise (closing
direction) from the standard position, the central screw
will rotate together with knob. This is normal, and the
screw will be in the completely open position in any case.
