11.10 Adjusting the riding sag
Preparatory work
–

–
Remove the shock absorber. ( p. 52)
–
After removing the shock absorber, clean it thoroughly.
B00292-10
Main work
–
Choose and mount a suitable spring.
Guideline
Spring rate
Weight of rider: 65… 75 kg (143…
165 lb.)
45 N/mm (257 lb/in)
Weight of rider: 75… 85 kg (165…
187 lb.)
48 N/mm (274 lb/in)
Weight of rider: 85… 95 kg (187…
209 lb.)
51 N/mm (291 lb/in)
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. ( p. 53)
–
Check the free travel of the foot brake lever. ( p. 75)
–
Remove the motorcycle from the lift stand. ( p. 45)
–
Check the static sag of the shock absorber. ( p. 39)
–
Check the riding sag of the shock absorber. ( p. 40)
–
Adjust the rebound damping of the shock absorber. ( p. 38)
11.11 Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the fork.
401000-01
–
As with the shock absorber, smaller differences in the rider's weight can be com-
pensated 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.
–
If the fork feels unusually hard after extended periods of operation, the fork legs
need to be bled.
11.12 Adjusting the compression damping of the fork
Info
The hydraulic compression damping determines the fork suspension behavior.
