M10 Suspension
Sag/Ride Height Settings
1. To check if the FRA settings are close before riding, check the
SAG settings. Raise the rear bumper until the suspension is fully
extended (rear shock will not extend any further). Measure the
distance from the ground to the bottom of the bumper as shown to
attain dimension X and record it.
2. Next, have the rider sit on the sled and bounce on the seat a couple
of times to set in the M10. While the rider remains seated, measure
the distance from the ground to the top of the bumper to attain
dimension Y and record it.
3. Next subtract Y from X and you will have the SAG settings (X - Y
= SAG SETTING or 21 - 17 = 4). The correct amount of SAG for
the M10 rear suspension is 3" - 5".
NOTE: The FRA setting is the primary rear suspension adjustment. It
will have the MOST effect on the rear suspension performance.
