–
Check the free travel of the foot brake lever. (
–
Remove the motorcycle from the lift stand. (

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. (
–
As with the shock absorber, smaller differences in the rider's weight can be com-
pensated by the spring preload.
–
However, if the fork is often overloaded (hard end stop on compression), harder
springs must be fit to avoid damage to the fork and frame.
