REAR SUSPENSION
M-10 SUSPENSION
M-10 OVERVIEW
The FAST M-10 rear suspension has been designed and set up
to deliver a soft ride under average riding conditions. Rider
weight, riding styles, trail conditions, and vehicle speed each
affect suspension action.
The suspension can be adjusted to suit rider preference and
deliver excellent performance for a given set of conditions. It
should be noted, however, that suspension adjustments
involve a compromise or trade off. A machine set up to
perform well in the moguls would not suit the preference of a
groomed trail rider.
M-10 ADJUSTMENTS
• Full Range Adjuster (FRA)
• Threaded Pre-load adjuster
• Rear Compression Spring Adjuster
• X-Over Tube Length Adjustment
IMPORTANT: The M-10 rear suspension has been
designed to be very sensitive to rider weight.
Changes in rider weight of 25 lbs. or more may
require appropriate changes in FRA settings.
M-10 TERMINOLOGY
• Couple Blocks: Plastic blocks located at the rear of
each rail. Blocks facilitate the couple function.
• Full Range Adjuster (FRA): FRA refers to the
adjustable lower rear shock attachments. Changing the
FRA location has two effects on tuning. First, moving
the shock forward increases shock speed, resulting in
firmer damping on compression and rebound. Second,
it also increases the effect of the rear spring by
displacing it further.
• Sag Settings: The difference in rear bumper height
from the sleds fully extended position to its lower
height with the rider seated on the sled.
