11 TUNING THE CHASSIS
47
–
Remove the motorcycle from the lift stand. ( p. 50)
11.10 Adjusting the riding sag
Preparatory work
–
Raise the motorcycle with the lift stand. ( p. 50)
–
Remove shock absorber. ( p. 57)
–
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.) 60 N/mm (343 lb/in)
Weight of rider: 75… 85 kg (165…
187 lb.) 63 N/mm (360 lb/in)
Weight of rider: 85… 95 kg (187…
209 lb.) 66 N/mm (377 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. 57)
–
Remove the motorcycle from the lift stand. ( p. 50)
–
Check the static sag of the shock absorber. ( p. 45)
–
Check the riding sag of the shock absorber. ( p. 46)
–
Adjust the rebound damping of the shock absorber. ( p. 44)
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.

Turn white adjusting screw

clockwise as far as it will go.
Info
Adjusting screw

is located at the upper end of the left fork leg.
The compression damping is located in left fork leg COMP (white adjusting
screw). The rebound damping is located in right fork leg REB (red adjusting
screw).
