THE PERFECT FIT
M-10 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) and 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 M-10. 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
M-10 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.
