WARNING!
When delivered, the Öhlins shock absorber is
dialed to the recommended settings for the spe-
cifi c brand and make of the motorcycle. Before
riding, always ensure that the basic settings
made by Öhlins are intact.
To set the adjuster:
The turn adjusters have a normal right hand
thread. Turn the damping adjusters clock-
wise to fully closed (position zero [0]). Then,
turn counter clockwise to open, and count
the clicks until you reach the recommended
number of clicks. See Set-up data.
Do not use force, delicate sealing surfaces can
be damaged. Handtighten only.
Spring pre-load
Loosen the screw of the spring platform
clamp. Use the C-spanner provided in
this kit, turn the spring platform to the
desired position. Or, when installed on
the vehicle, turn the spring by hand.
Tighten the screw of the spring platform
clamp when done with the adjustment.
Compression damping:
Adjustments are made on top of the
reservoir.
Low speed: Slotted centre screw.
High speed: Hexagon screw.
NOTE!
When the shock absorber is installed
the compression can be adjusted from
above. Remove the seat and use a
wrench to adjust. See fi gure below.
Rebound damping:
Adjust by turning the wheel on the piston
shaft above the end bracket.
