Warning!
Before riding, always make sure that the
basic settings made by Öhlins are according

adjustments and setting up in the Öhlins
Owner’s Manual before you make any
adjustments. Contact an Öhlins dealer if you

Rebound and Compression Damping
Use an allen key. Turn the adjuster clockwise
to increase the damping, turn counter
clockwise to decrease it.
Spring Preload
Loosen the platform clamp screw. Use
an allen key.
Use a C-spanner and move the spring
platform to the desired position (2A).
Or, turn the spring by hand to the
desired position (2B).
The spring platform and the spring
are press fitted, therefore, by turning the
spring you will move the spring platform.
Tighten the platform clamp screw.
CSC Adjuster
Use an allen key and turn the screw. Turn
clockwise to increase the damping, turn
counter clockwise to decrease.
Note!
Since the CSC valve is designed to compensate
for temperature changes, the number of clicks
will differ slightly between a cold and a warm
shock absorber. The recommended setting is at
room temperature.
Caution!
Do not use force, delicate sealing surfaces can
be damaged.
