Make sure the vehicle is securely supported so
that it will not tip.
2
Remove the silencer.
3
Remove the upper screw of the original shock
absorber.
4
Remove the lower screw of the link arm and
the lower screw of the original shock absorber.
WARNING!
It is advisable to have an Öhlins dealer install the
shock absorber.
ADJUSTMENTS

Spring Pre-load
Turn the Hydraulic Adjuster knob to set
the spring pre-load. Turn clockwise to
increase the pre-load and turn counter
clockwise to decrease.
Compression Damping
Adjust by turning the gold knob labelled
“COMP” on the cylinder head (1). Or,
use a 14 mm socket T-bar and turn the
hexagon nut on the adjuster knob (2).
Turn clockwise to increase damping, turn
counter clockwise to decrease.
Rebound Damping
Adjust by turning the black knob labelled
“REB” on the cylinder head (1). Or, use
a 14 mm socket T-bar and turn the
hexagon nut on the adjuster knob (2).
Turn clockwise to increase damping, turn
counter clockwise to decrease.
NOTE!
When delivered the Öhlins shock absorber
is dialed to the recommended settings
for the specifi c vehicle model. If you have
changed the setting, reset according to
the following:
The adjuster has a right hand thread. Turn
the adjuster clockwise to fully closed
(pos. zero [0]). Turn counter clockwise to
open and count the clicks until you reach
the recommended number (see Set-up
Data).
CAUTION!
Do not use force, delicate sealing surfaces
can be damaged. Handtighten only.
Length Adjustment
We advise to remove the shock absorber
from the vehicle before adjusting the
length. Use two 24 mm wrenches. Hold
the upper nut with one hand and at the
same time loosen the lock nut (lower nut).
Turn the end eye/bracket to the desired
length. Tightening torque: 40 Nm
WARNING!
Remember to lock the lock nut after adjusting
the length.
WARNING!
The adjustable end eye/bracket must not be
threaded out more than that the groove is fully
visible beneath the lock nut. This is maximum
length. After adjusting, make sure that the lock
nut is tightened.

Remove the original shock absorber by lifting it
above the rear wheel.
NOTE!
Recommendation! Before installing the Öhlins
shock absorber:
• clean the vehicle thoroughly
• adjust the length of the shock absorber (check
the headlight angle after adjusting the length!)
6
Loosen the screw holding the brake fl uid res-
ervoir (on the inside of the right frame beam).
Press the brake fl uid reservoir as far towards
the front as possible, then tighten the screw.
7
Install the Öhlins shock absorber in the same
way as the original unit. Use the original
screws.
NOTE!
Make sure that there is clearance between the
shock absorber reservoir and the brake fl uid
reservoir.
NOTE!
Lower the motorcycle so that the shock absorber
is sligthly compressed, before tightening the
screws.
8
Reinstall the silencer. Make sure that all re-
moved parts are installed in the same way as
they were before the installation.

CAUTION!
The brake hose must not be stretched. It can
be damaged. Support the swing arm once the
lower screw of the shock absorber is removed.
WARNING!
Make sure that all screws are tightened to the
correct torque and that nothing fouls or restricts
movement of the shock absorber when the sus-
pension is fully compressed or extended.
Before riding, always ensure that the basic set-
tings made by Öhlins are intact.
