Adjusting compression damping of fork
Hydraulic compression damping determines the reaction when the fork is compressed. The
degree of compression can be adjusted with adjusting screws at the bottom of the fork legs.
Carefully pry out the protection cover [1] with a screwdriver and remove.
Turn the adjusting screws [2] clockwise to increase damping, turn it counterclockwise to
reduce damping during compression. Make the same damping rate adjustments to both fork
legs.
STANDARD ADJUSTMENT
– Turn adjusting screw clockwise as far as it will go.
– Turn 15 clicks in a counterclockwise direction.
Adjusting rebound damping of fork
Hydraulic rebound damping determines the reaction when the fork is 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 dur-
ing rebounding. Make the same damping rate adjustment to both fork legs.
STANDARD ADJUSTMENT
– Turn adjusting screw clockwise as far as it will go.
– Turn 18 clicks in a counterclockwise direction.

Adjusting the fork and shock absorber
There are a number of ways to adjust the fork and shock absorber to match the chassis to
your driving style and the payload.
We have provided a table with pragmatical values to help you tune up your motorcycle. These
tune-up specifications are reference values only and should serve as a basis for your per-
sonal chassis and suspension tuning. Do not make arbitrary changes to the settings (maxi-
mum ±40%) since this may impair the handling characteristics (particularly in the high-
speed range).
We recommend the "Driving Sport" damping adjustment for off-road rides on soft subgrades
(e.g. sand) and the "Driving Comfort" damping adjustment for off-road rides on hard sub-
grades (e.g. rocks).
