Suspension Adjustment
Front Fork Adjustment
A shock has two main actions: compression when
the shock gets loaded, and rebound when the shock
returns back to full length. Compression damping is
the adjustment that determines how fast or slow the
fork compresses. Rebound damping is the
adjustment that determines how fast or slow the fork
rebounds.
1. Bleed Screw - The Allen screw (A) at the top of
the fork leg is the “bleed” screw. The bleed screw
serves two purposes:
•
Transporting your motorcycle. See Transporting
on page 1-15.
•
Bleeding the fork: Bleed the fork regularly, let
any excess air out after each ride.
2. Rebound Damping - The rebound damping is
adjusted by turning the slotted brass adjuster
screw (B) on the top of both fork legs. Next to it
will be the writing S-F, meaning Slow and Fast.

The adjuster has 18 stages of adjustment.
This determines how quickly the fork returns to its
extended position after being compressed.
Turning the rebound adjuster screw clockwise will
slow the rebound speed down making it better for
larger, rolling terrain or bumps. Turning the
rebound adjuster screw counter-clockwise will
increase the rebound speed making it better for
smaller, rougher bumps. Adjust each fork leg
evenly.
