Adjusting the preload of the shock absorber
The baggage and passenger put the main load on the shock absorber. To guarantee maxi-
mum handling performance, the preload of the shock absorber must be adapted to the load.
The preload is hydraulically adjusted by turning the hand wheel
[1]. Turning in a clockwise
direction will increase the preload, turning in a counterclockwise direction will reduce the
preload.
Our pragmatical values are provided in the table "Basic settings for the shock absorber" to
help you to make the necessary adjustments.
STANDARD ADJUSTMENT:
– Turn the hand wheel in a counterclockwise direction up to the stop
– Turn the hand wheel 6 turns in a clockwise direction
Breathing the fork legs
Breath the fork legs regularly (see Maintenance Schedule).
To breath, place the motorcycle on the side stand and briefly remove the bleeder screws
[2]
to allow any overpressure to escape from the fork.
Excessive pressure in the interior of the fork can cause leaks in the fork. If your fork is leak-
ing, it is recommended to open the breather plugs before having the seals replaced.
