ADJUSTABLE SUSPENSION
Front fork adjustment
Note
Always set the spring loads in both fork legs equally, to
obtain optimum suspension performance.
Each Fork leg is provided with a spring PRELOAD adjusting
bolt, the right leg is provided with a COMPRESSION
damping force and left leg is provided with REBOUND
damping force, through damping adjuster screw.
Spring preload
Increasing the spring preload will harden the
suspension. To decrease the spring preload, thereby
soften the suspension. Turn the bolt as indicated in
the Fig 36.
The spring preload setting is determined by the
distance A or no of groove, Shorter the distance A or
no of groove indicates higher preload by rotating the
preload adjusting bolt clockwise, higher the distance
A or no of groove indicates lower preload rotating the
preload adjusting bolt anti-clockwise.
