STEERING DAMPER ADJUSTMENT
STEERING DAMPER ADJUSTMENT
The steering damper is a hydraulic damper that
counteracts wobble, alleviates shock against the
front wheel and prevents head shake/cast by the
motorcycle, which gives safer riding. The damper is
fitted on the upper fork crown, in the centre over the
steering stem
1
. When turning, and in the event of
wobbling, shock, etc, the link arm of the damper is
twisted, thus forcing fluid through three independ-
ently acting valve systems in the damper cover.
Setting
The steering damper has three external setting
possibilities, i.e., setting of the damper valve, high-
speed valve and sweep valve, which regulate the
damping area

.
Low speed valve
The steering damper is delivered with the low
speed valve set in a basic position that gives max-
imum basic damping. For enduro and motocross it
is suitable to set the low speed in position 4-8, de-
pending on the track and the rider.
Turn clockwise to increase damping and counter
clockwise to reduce it

.
High speed valve
The high-speed valve
4
is set between 11/4 to 2
turns from the bottom position, suitable for enduro,
motocross and off-road. For all riding, the high-
speed valve must be set screwed up at least 1
turn from the bottom.
