Info
For various reasons, no exact riding sag can be determined for the fork.
–
Check the free travel of the foot brake lever. (
–
Remove the motorcycle from the lift stand. (
Preparatory work
–
Raise the motorcycle with a lift stand. (
–
Remove the shock absorber.
–
After removing the shock absorber, clean it thoroughly.

Finishing work
–
Install the shock absorber.
–
Check the free travel of the foot brake lever. (
–
Check the static sag of the shock absorber. (
–
Check the riding sag of the shock absorber. (
–
Adjust the rebound damping of the shock absorber. (
–
Remove the motorcycle from the lift stand. (
–
Smaller differences in the rider's weight can be compensated for by the fork air
pressure.
–
However, if the fork frequently bottoms out (hard end stop on compression), the
fork air pressure must be increased, within the specified values, to avoid damage to
the fork and frame.
–
If the fork feels unusually hard after extended periods of operation, the fork legs
need to be bled.
