Changing the spring preloading of the shock absorber
The spring preload can be changed by turning the adjusting ring
1
. For this
purpose, you should dismount the shock absorber and clean it thoroughly.
NOTE:
– Before changing the spring preload note down the basic setting, e.g.
how many threads are visible above the adjusting ring.
– One rotation of the adjusting ring
1
changes the spring pretension by
approximately 1,75 mm (0,07 in).
Loosen the clamping screw
2
and use the hook wrench contained in the
vehicle tool set to turn the adjusting ring as desired. Turning it counter-
clockwise will reduce the preload, turning it clockwise will increase the
preload.
After readjusting the clamping screw
2
, tighten it to 8 Nm (6 ft.lb)

Pivot bearing
The pivot bearing
3
for PDS suspension struts at the swinging fork is
Teflon-coated and must not be lubricated with either grease or other lubri-
cants. Grease and other lubricants cause the Teflon coat to dissolve,
whereby the bearing’s lifecycle will be reduced dramatically.
When cleaning your bike with a high-pressure cleaner, do not aim the high-
pressure spray directly at the pivot bearing.
Check chain tension
To check the chain tension, park the motorcycle.
Press chain upward at the end of the chain sliding component. The distance
between chain and swing arm should be approx. 15 mm (0.6 in). In the
course of this procedure, the upper chain portion
A
must be taut (see
illustration).
If necessary, correct chain tension.
