THE PERFECT FIT
FAST M-10 Rear Suspension Adjustments
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 suspen-
sion.
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 suspen-
sion, sag is controlled by two settings, the full range adjuster (FRA)
position and the rear spring preload.
