Steering damper (fig. 16)
The steering damper is before the tank and is secured to
the frame and the steering head.
It gives improved steering accuracy and stability, thus
also improving motorcycle road behavior under any riding
conditions.
Important
In case the steering damper position is changed,
the steering damper must be adjusted (see page 45).

Front fork adjusters 748/748S/998
The front fork has rebound and compression damping
adjusters.
This adjustment is done using the outer adjusters:
1) (fig. 17.1) to adjust rebound damping;
2) (fig. 17.1) to adjust inner springs preload;
3) (fig. 17.2) to adjust compression damping.
Put and secure the motorcycle in vertical position.
Turn the adjuster (1) on fork leg top with a flat
screwdriver to adjust rebound damping.
To reach the adjuster (3), insert a screwdriver into the
passing hole on the wheel spindle at fork leg axis.
As you turn the adjusting screws (1 and 3), you will hear
them click. Each click identifies a setting.Turn the screw
all the way in to set the hardest damping (position 0).
This will be your starting point. Now turn the screw
anticlockwise and listen for the clicks that identify setting
positions no. "1", "2" and so on.
