the spring by turning the adjustment collar clockwise on
the shock.
Rebound Adjustment
The rebound adjuster knob (A) is at the bottom of the
shock. It has 8 stages of adjustment. Printed on the knob is
“H” meaning
Hard (slower rebound) and “S” meaning Soft
(faster rebound). The ride quality adjustment knob controls
the hardness or softness the ride quality of your
motorcycle. Turning the knob clockwise, or H direction, is
good for big impacts.
Turning the knob counter-clockwise, or S direction, is good
for smaller and more frequent impacts.
Note: Adjusters should never be forced completely “Soft”
or “Hard”; always leave one click of adjustment in either
direction.
