THE PERFECT FIT
EDGE Rear Suspension Adjustments
Initial Spring Preload Setting (Sag Method)
To set up the EDGE rear suspen-
sion torsion spring preload, mea-
sure the distance between the
ground and rear bumper. This is
measurement X.
Take the first measurement with
no rider and with the rear suspen-
sion at full extension.
NOTE: The rear bumper may
need to be lifted upward
slightly to fully extend the
rear suspension.
Next, have the rider drop down
hard on the seat and bounce up
and down several times, collaps-
ing the rear suspension. With the
rider seated, measure the distance
between the ground and the rear
bumper at the exact location used
for measurement X. This is mea-
surement Y.
To determine sag, commonly referred to as ride-in, subtract measure-
ment Y from X (sag=X-Y). Adjust sag by rotating the torsion spring
preload cams located on the rear torque arm. Use the illustration for ref-
erence. The ideal amount of Sag for the EDGE rear suspension is four
inches (X-Y=4).
If the rear suspension rides in less than three inches or more than five
inches with the torsion spring preload cams at their maximum range of
adjustment, optional torsion springs (softer or stiffer, respectively) may
be required. This is only an initial set-up, and final spring preload may
vary based on rider preference and riding conditions.
