Adjusting the spring preload on the fork

The fork spring preload can be adjusted by turning the adjusting screws [1]
(wrench size 24 mm) ± 5 mm (0,2 in).
1
Turning in a clockwise direction will increase the preload, turning in a coun-
terclockwise direction will decrease the preload. 1 turn will change the pre-
load by 1 mm.
Changing the preload will not affect the rebound damping adjustment, although
adjusting screw [2] will turn at the same time.
Generally, if the preload is higher, the rebound damping should also be set
2
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 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 counter-
clockwise will decrease the damping.
STANDARD ADJUSTMENT LOW-SPEED:
– Turn adjusting screw [3] clockwise as far as it will go.
– Turn 20 clicks in a counterclockwise direction.
3
STANDARD ADJUSTMENT HIGH-SPEED:
– Turn adjusting screw (wrench size 17 mm) clockwise as far as it will go.
– Turn 2 turns 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
ANYMAINTENANCE WORK YOURSELF. SEVERE INJURIES COULD BE THE RESULT.
NEVER UNSCREW THE BLACK SCREW CONNECTION (24MM).
