also improving motorcycle road behavior under any riding
conditions.
(999S)
Turn the knob (1) clockwise for a harder setting,
counterclockwise for a softer setting. A click identifies
E
the different settings.
Warning (999S)
Never attempt to set knob (1) while riding, or you
may lose control of the motorcycle.
Important
In case the steering angle is changed, the steering
damper must be repositioned (see page 66-68).
