THE PERFECT FIT

Rear Suspension Adjustments

Initial Spring Preload Setting (Sag Method)

To set up the 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 measure-

ment X. This is measurement 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. See illustration. The ideal

amount of sag for this rear suspension is five inches (12.7 cm) (X-Y=5

in./12.7 cm).
If the rear suspension rides in less than four inches or more than six

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.
