THE PERFECT FIT
Rear Suspension Adjustments
Initial Spring Preload Setting (Sag Method)
X
Y
To set up the EDGE RMK rear suspension torsion spring preload, mea-
sure the distance between the ground and rear bumper (see illustration).
This measurement should be taken with no rider and the rear suspension
at full extension. This is measurement X.
Take the first measurement with no rider and with the rear suspension at
full extension.
Tip: 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, collapsing 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 measurement Y.
