Compression damping of fork

Hydraulic compression damping determines the reaction when the fork is com-
pressed. The degree of compression can be adjusted with adjusting
1
screws at the bottom of the fork legs.Remove the protecting cap [1].
Turn the adjusting screws [2] clockwise to increase damping, turn it counter-
clockwise to reduce damping during compression.
STANDARD ADJUSTMENT
– turn adjusting screw clockwise as far as it will go
– turn it back by as many clicks as are specified for the relevant type of fork

Rebound damping of fork

Hydraulic rebound damping determines the reaction when the fork is
3
rebound. By turning the adjusting screw [3] (REB), the degree of damping of
the rebound can be adjusted. Turn the knob clockwise to increase damping,
turn it counterclockwise to reduce damping during rebounding.
STANDARD ADJUSTMENT
– turn adjusting screw clockwise as far as it will go
– turn it back by as many clicks as are specified for the relevant type of fork

Damping action during compression of shock absorber (SX, XC USA)
The shock absorber on the SX models can synchronize the compression
damping in the low and high-speed range separately (Dual Compression
Control).
Low and high speed refers to the movement of the shock absorber during com-
pression and not to the speed of the motorcycle.
The low and high-speed technology overlaps.
The low-speed setting is primarily for slow to normal shock absorber compres-
sion rates.
The high-speed setting is effective at fast compression rates.
Turning in a clockwise direction will increase the damping, turning
counterclockwise will decrease the damping.
STANDARD LOW-SPEED SETTING:
– turn the adjusting screw [4] to the limit in a clockwise direction using a
6
screwdriver .
– unscrew the respective number of clicks for the specific type of shock absorber
in a counterclockwise direction.

STANDARD HIGH-SPEED SETTING:
– turn the adjusting screw [5] to the limit in a clockwise direction using a
box wrench.
– unscrew the respective number of turns for the specific type of shock absorber
in a counterclockwise direction.

THE DAMPING UNIT OF THE SHOCK ABSORBER IS FILLED WITH HIGH-COMPRES-
SION NITROGEN. NEVER TRY TO TAKE THE SHOCK ABSORBER APART OR TO DO
ANY MAINTENANCE WORK YOURSELF. SEVERE INJURIES COULD BE THE RESULT.
NEVER UNSCREW THE BLACK SCREW CONNECTION [6] (24MM).
