Rear Suspension Adjustments

Rear Suspension 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 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.

To determine sag, commonly referred to as ride-in, subtract

X

Y

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.
