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 2.
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 3.
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.
