TUNING THE CHASSIS 34
– Lock the seat. ( p. 45)
– Remove the motorcycle from the lift stand. ( p. 37)
9.10Adjusting the riding sag x
Preliminary work
– Raise the motorcycle with the lift stand. ( p. 37)
– Fold the seat up. ( p. 44)
–
Remove the shock absorber. x ( p. 43)
– 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.)
58 N/mm (331 lb/in)
Weight of rider: 75… 85 kg (165…
187 lb.)
62 N/mm (354 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.
Subsequent work
–
Install the shock absorber. x ( p. 43)
– Lock the seat. ( p. 45)
– Remove the motorcycle from the lift stand. ( p. 37)
– Check the static sag of the shock absorber. ( p. 32)
– Check the riding sag of the shock absorber. ( p. 33)
– Adjust the rebound damping of the shock absorber. ( p. 31)
9.11Checking the basic setting of the fork
Info
For various reasons, no exact riding sag can be determined for the forks.
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 is often overloaded (hard end stop on compression), harder
springs must be fit to avoid damage to the fork and frame.
9.12Adjusting the compression damping of the fork
Info
The hydraulic compression damping determines the fork suspension behavior.
