Adjusting the fork and shock absorber

Super Duke R
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).
Make sure both fork legs are equally adjusted.
A sticker with the basic settings is located under the seat.

Adjusting compression damping of fork

Hydraulic compression damping determines the reaction when the fork is compressed.
Turn the adjusting screws [1] clockwise to increase damping, turn it counterclockwise to
reduce damping during compression. Make the same damping rate adjustment to both fork
legs.
STANDARD ADJUSTMENT
– Turn adjusting screw clockwise as far as it will go.
– Super Duke: Turn 15 clicks in a counterclockwise direction.
– Super Duke R: Turn 18 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 [2] (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.
