Finishing work
– Install the shock absorber. ( p. 56)
– Remove the motorcycle from the lift stand. ( p. 45)
– Check the static sag of the shock absorber. ( p. 37)
– Check the riding sag of the shock absorber. ( p. 38)
– Adjust the rebound damping of the shock absorber. ( p. 36)
10.12 Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the fork.

– 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.
10.13 Adjusting the fork air pressure
Warning
Danger of accidents Modifications to the suspension setting may seriously alter the handling characteris-
tic.
Extreme modifications to the suspension setting may cause a serious deterioration in the handling char-
acteristic and overload components.
– Only make adjustments within the recommended range.
– Make sure your child rides slowly to start with after making adjustments in order that he or she can
assess the new handling characteristic.
