Front Suspension Adjustments
112 Adjustments for Competition
Front Suspension Adjustments
The front suspension can be adjusted for the rider’s
weight and riding conditions by using one or more
of the following methods:
Compression damping — Turning the
compression damping adjuster (1) adjusts how
quickly the fork compresses.
Rebound damping — Turning the rebound
damping adjuster (2) adjusts how quickly the
fork extends.
Fork spring — Adjusting the PSF air pressure
and oil capacity adjusts the spring rate from
soft to sfiff.
Compression Damping Adjustment
This adjustment affects how quickly the fork
compresses. The fork compression damping
adjuster (1) has 18 positions or more. Turning the
adjuster screw one full turn changes the adjuster
four positions. To adjust the compression damping
to the standard position, proceed as follows:
Turn the adjuster clockwise until it will no longer
turn (lightly seats). This is the full hard position.
The adjuster is set in the standard position when
the adjuster is turned counterclockwise 14 clicks.
Make sure that both fork legs are adjusted to the
same position.
Rebound Damping Adjustment
The fork rebound damping adjuster (2) has 16
positions or more. Turning the adjuster screw one
full turn clockwise advances the adjuster four
positions. To adjust the rebound damping to the
standard setting, proceed as follows:
Turn the adjuster clockwise until it will no longer
turn (lightly seats). This is the full hard position.
The adjuster is set in the standard position when
the adjuster is turned counterclockwise 11 clicks.
Make sure that both fork legs are adjusted to the
same position.
Both compression and rebound damping can be
increased by turning the adjuster clockwise.
NOTICE
Always start with full hard when adjusting
damping.
Do not turn the adjuster screw more than the given
positions or the adjuster may be damaged.
Be sure that the compression and rebound
adjusters are firmly located in a detent, and not
between positions.
