How to change the handlebar position
The handlebar position can be readjusted by 22 mm. Thus, you can put the
handlebar in the position that is the most convenient for you. The upper tri-
ple clamp
1
includes 2 bores arranged at a distance of 15 mm (0.6 in) from
one another. The bores at the handlebar support
2
are offset from the cen-
ter by 3.5 mm (0.13 in). Accordingly, you can mount the handlebar in
4 different positions.
For this purpose, remove screws
3
of the handlebar clamps and screws
4
of the handlebar support. Position the handlebar support, and tighten
screws
4
to 40 Nm. Mount handlebar and handlebar clamps, and tighten
screws
3
to 20 Nm. The gap between the handlebar support and the
handlebar clamps should be the same in the front and in the rear.

Changing the spring preloading of the shock absorber
The spring preload can be changed by turning the adjusting ring
5
. 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
5
changes the spring pretension by
approximately 1.75 mm (0.07 in).
Loosen the clamping screw
6
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
6
, tighten it to 8 Nm.

Pivot bearing
The pivot bearing
7
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.
