WITH SET-UP DATA
Set-up Data
Spring preload 21 mm
Shock absorber length 360.5 mm
Stroke 105 mm
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
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. 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
Adjust the spring preload by changing
the position of the upper spring seat.
