HOW TO INSTALL
1
Put the motorcycle on a workstand so that the
rear wheel barely touches the ground.
WARNING!
Make sure the vehicle is securely supported so
that it will not tip.
2
Remove the original shock absorbers. Consult
your Vehicle Service Manual.
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!)
3
Install the Öhlins shock absorbers in the same
way as the original units. The shock absorber
should be installed with the cylinder head at
the top and the reservoir towards the rear. Use
the washers and sleeves provided in this kit.
NOTE!
Lower the motorcycle so that the shock
absorber is sligthly compressed, before tighten-
ing the screws.
WARNING!
It is advisable to have an Öhlins dealer install the
shock absorber.
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.
Always ensure that the basic settings made by
Öhlins are intact.
ADJUSTMENTS
Spring Preload
Use the C-spanner provided in this kit.
Turn the spring platform nut (A) to set the
spring preload. Lock the setting with the
lock nut (B).
Length
Use two 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.
Lock the lock nut.
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.
