Adjusting the spring preload on the fork
The fork spring preload can be adjusted by turning the adjusting screws [2] (wrench size 24
mm) ± 5 mm (0,2 in).
Turning in a clockwise direction will increase the preload, turning in a counterclockwise direc-
tion will decrease the preload. 1 turn will change the preload by 1 mm.
Changing the preload will not affect the rebound damping adjustment, although adjusting
screw [1 will turn at the same time. Make the same spring preload adjustments to both fork
legs.
Generally, if the preload is higher, the rebound damping should also be set higher.
STANDARD ADJUSTMENT:
Turn adjusting screw counterclockwise as far as it will go.
Turn 5 turns in a clockwise direction.

Compression damping of shock absorber
The shock absorber 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 compression 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 compression 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.
