Front fork adjusters
The front fork used on this motorcycle has rebound
(return), compression and spring preload adjustment.
It is possible to adjust the spring preload on both legs
whereas compression and rebound can only be
adjusted on the LH and RH legs, respectively.
Adjustment is done by external screw adjusters:
1) for rebound adjustment;
2) for inner spring preload adjustment;
3) for compression adjustment.
Put the motorcycle on the side stand and make sure it
is stable. Turn adjuster (1) at the top end of the RH fork
leg with a suitable screwdriver to adjust rebound.
Turn adjuster (3) at the top end of the LH fork leg with
a screwdriver to adjust compression. By turning
adjuster screws (1) and (3) you will hear some clicks;
each click corresponds to a damping setting.
The stiffest damping setting is obtained with the
adjuster turned fully clockwise to the "0" position.
By turning counter clockwise starting from this
position, count the clicks that will correspond to
positions "1", "2" etc.
STANDARD settings are as follows:

hexagon wrench, completely counter clockwise, to
obtain fully uncompressed position. From this
position, adjust the spring preload by turning the
