–
Check the static sag of the shock absorber. ( p. 27)
–
Check the riding sag of the shock absorber. ( p. 28)
–
Adjust the rebound damping of the shock absorber. ( p. 26)
10.12 Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the fork.

(50 SX)
–
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.
(50 SX Mini)
–
As with the shock absorber, smaller differences in the rider's weight can be
compensated by the spring preload.
–
However, if the fork frequently bottoms out (hard end stop on compression),
harder springs must be fitted to avoid damage to the fork and frame.
10.13 Adjusting the fork air pressure (50 SX)
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. ( p. 34)

Main work
–
Remove protection cap

.
–
Push fork pump  together fully.
Fork pump (79412966000)
–
Connect the fork pump to the left fork leg.
The fork pump indicator switches on automatically.
A little air escapes from the fork leg when connecting.
Info
This is due to the volume of the hose and not due to a defect in the fork
pump or the fork.
Read the accompanying
KTM PowerParts instructions.
–
Adjust the air pressure as specified.
Guideline
Air pressure 2 bar (29 psi)
Gradual changing of the air pressure in
steps of 0.2 bar (3 psi)
Minimum air pressure 1.4 bar (20 psi)
Maximum air pressure 4 bar (58 psi)
