FAST M-10 Rear Suspension Adjustments THE PERFECT FIT The M-10 suspension has been designed to be very sensitive to rider weight. Changes in rider weight of 25 lbs. (11 kg) or more might require appropriate changes in settings. The following information has been compiled to assist you in tuning your M-10 suspension to its maximum potential and achieve the best possible ride. Please take the time to read and understand all the possible adjustments available with this suspension. Static Sag and Ride Height Settings Static sag describes the difference in height of the rear bumper from the suspension's fully extended position to its loaded height, with the rider seated on the snowmobile. Too much sag will result in bottoming, and too little sag will result in reduced rider comfort. Sag is used to control ride quality and rebound travel. On this suspension, sag is controlled by two settings, the full range adjuster (FRA) position and the rear spring preload. 1. To check sag, raise the rear bumper until the suspension is fully extended (the rear shock will not extend any further). Measure the distance from the ground to the bottom of the bumper (dimension X) as shown in the illustration. Record the measurement. 2. Have the rider sit on the snowmobile and bounce up and down on the seat a few times to set in the suspension. While the rider remains seated, measure the distance from the ground to the top of the bumper (dimension Y) and record it. 3. Subtract Y from X and you will have the SAG setting (X - Y = sag setting. Example: 21 - 17 = 4). The correct amount of SAG for the FAST M-10 rear suspension is 3-4 inches (8-10 cm). If the measured sag is incorrect, adjust the FRA position and rear spring preload.
