THE PERFECT FIT
M10 Suspension
M10 Features
NOTE: The M10 has been designed to be very sensitive to rider
weight. Changes in rider weight of 25 lbs. or more might require ap-
propriate changes in FRA settings. Refer to the chart on page 42 for
specifications.
Internal Floating Piston Shock - A high-pressure gas shock absorber,
with its gas reservoir inside the main shock body. Shock oil, is kept
separate from the gas by means of a floating internal piston. The shock
used on the front arm of the M10 is of this type. The advantages of
these shocks are consistency and reduced fade performance.
Remote Reservoir Shock - When a shock’s nitrogen and oil are
separated by a floating piston or bladder in an external chamber, they
are referred to as REMOTE RESERVOIR shocks. Some advantages of
this type of shock are consistency in shock performance, reliability, and
reduced fade performance. The M10’s rear shock absorber is of this
type.
Threaded Preload Adjuster - The top section of the X-OVER TUBE
(back tube at the top of the rear shock) has a threaded collar on it. The
rear spring has a lock tab that fits into the collar to allow easy
PRELOAD adjustment.
To increase PRELOAD, use a kit spanner wrench to rotate the
X-OVER TUBE towards the PTO side of the sled (clockwise when
viewed from below). Rotate towards the MAG side to decrease
PRELOAD (counter-clockwise when viewed from below). For more
information, refer to page 44.
Tuning Terms
Spring Rates - Describes how many pounds of force it takes to
compress a spring one inch. Therefore, if a 250 lb. weight was set on
top of a spring and it compressed one inch, it would be rated at 250
lbs./inch.
