Adjusting the riding sag
12.11
Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the fork.
Preparatory work
–
Deactivate the vehicle. (
–
Fold the seat up. (
–
Remove the KTM PowerPack. (
–
Mount the covering cap. (
–
Raise the motorcycle with a lift stand. (
–
Remove the shock absorber.
–
After removing the shock absorber, clean it thoroughly.
Main work
–
Choose and mount a suitable spring.
Guideline
Spring rate
Weight of rider: 65 ...
75 kg (143 ... 165 lb.)
Weight of rider: 75 ...
85 kg (165 ... 187 lb.)
Weight of rider: 85 ...
B00292-10
95 kg (187 ... 209 lb.)
Info
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. (
–
Install the KTM PowerPack. (
–
Lock the seat. (
–
As with the shock absorber, smaller differences in the rider's
weight can be compensated by the spring preload.
–
However, if the fork is often overloaded (hard end stop on com-
pression), harder springs must be fit to avoid damage to the
fork and frame.
