Adjusting the riding sag
10.12
Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the fork.
10.13
Adjusting the fork air pressure
Warning
Danger of accidents Modifications to the suspension setting may seriously alter the handling characteristic.
Extreme modifications to the suspension setting may cause a serious deterioration in the handling characteristic 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 han-
dling characteristic.
Info
Check or adjust the air pressure under the same conditions at the earliest 5 minutes after switching off the engine.
The air suspension is located in the left fork leg. The rebound damping is located in the right fork leg.
Preparatory work
–
Raise the motorcycle with a lift stand. (
–
Remove shock absorber.
–
After removing the shock absorber, clean it thoroughly.
Main work
–
Choose and mount a suitable spring.
Guideline
Spring rate
Weight of rider: 35 kg (77 lb.)
Weight of rider: 40 kg (88 lb.)
Weight of rider: 45 kg (99 lb.)
Info
B00292-10
The spring rate is shown on the outside of the spring.
Smaller weight differences can be compensated by changing the spring
preload.
Finishing work
–
Install the shock absorber.
–
Remove the motorcycle from the lift stand. (
–
Check the static sag of the shock absorber. (
–
Check the riding sag of the shock absorber. (
–
Adjust the rebound damping of the shock absorber. (
–
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.
