Rear Suspension Adjustments
Rear Suspensio n Initial Spring Preload Setting
EDGE RMK (Sag Method)
To set up the EDGE RMK rear
suspension torsion spring preload,
measure the distance between the
ground and rear bumper. This is
measurement X.
Take this measurement with no rider
and with the rear suspension at full
extension. NOTE: The rear bumper
may need to be lifted upward
slightly to fully extend the
suspension.
Next, have the rider drop down hard
on the seat and bounce up and down
several times, collapsing t he 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 measurement Y.
To determine sag, commonly
referred to as ride-in, subtract
measurement Y from X (Sag=X-Y). Adjust sag by rotating the torsion
spring preload cams located on the rear torque arm. Use the illustration
or the decal found under the hood for reference. The ideal amount of
sag for the EDGE RMK 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 setup, and final spring preload may
vary based on rider preference and riding conditions.
