SHOCK ABSORBER

ADJUSTING THE HYDRAULIC COMPRES-
SION DAMPER (high and low speeds)
The shock absorber can be adjusted for
both high and low speeds. The terms 'high'
and 'low' refer to the compression speed
of the shock absorber, not to the speed of
the vehicle. The low-speed adjustment af-
fects the behaviour of the shock absorber
during low-speed compression; conversely
the high-speed adjustment affects its be-
haviour during high-speed compression.
Low-speed adjustment
•Using a screwdriver, loosen screw C by
turning it clockwise to decrease the hy-
draulic compression damper.
Standard adjustment RR 4t:
Screw completely open, 21/21 clicks
Standard adjustment RR 4t Racing:
Screw completely open, 21/21 clicks
High-speed adjustment
•Turn knob D anticlockwise to decrease
the hydraulic compression damper.
Standard adjustment RR 4t:
Knob completely open, 24/24 clicks
Standard adjustment RR 4t Racing:
Knob completely open, 24/24 clicks
WARNING
Starting from the standard position, turn the
knob anticlockwise (with a closing action).
The central screw will move along with the
knob. This is normal, as the screw will be
in completely open position anyway.

ADJUSTING THE SPRING PRELOAD

To adjust the spring preload, use the proce-
dure described below. Loosen counter-ring E.
Rotate ring F clockwise to increase the spring
preload (and consequently the shock absorber
E
preload) or anticlockwise to decrease it. After
obtaining the desired preload, turn counter-ring
F
E until it stops against adjusting ring F.
Spring preload RR 4t: 260 mm
