REAR SUSPENSION
M-10 FRA Initial Set Up Reference
The FRA setting is the primary rear suspension adjustment. It
will have the MOST effect on the rear suspension performance.
To adjust the FRA:.
1. Refer to the initial set-up reference chart to determine the
desired FRA position.
2. To adjust, loosen the hex bolts attaching the rear lower
shock cross shaft to the rail beam.
3. Using a 9/16" wrench, loosen the jam nuts on the preload
bolts.
4. Adjust the preload bolts to the desired FRA position.
5. Tighten the jam nuts.
NOTE: Make sure the preload bolt contacts the slide
block before tightening the jam nut.
6. Tighten the hex bolts and torque to 35 ft. lbs. (47 N-m)
NOTE: When the M-10 suspension is new, it will take
from 25 to 200 miles (40-300 km) to properly break in
the springs and shocks, at which time the
suspension will be softer and may require FRA re-
adjustment.
M-10 Rear Spring Preload
If FRA position alone does not allow the setup of the proper
amount of sag, the center retainer of the rear track shock can be
replaced with optional retainers to adjust the preload and change
the sag.
NOTE: Whenever ordering any of the retainers listed
in the chart, always order the retainer insert as well.
The insert is not removable once installed, so a new
insert is needed when installing a new retainer.
M-10 Ski Pressure
Ski pressure is set at the factory to deliver the optimum balance
between ride and handling. If a rider prefers more ski pressure
for improved steering performance, adjustments can be made to
the front limiter strap and front arm mount.
1. Determine if the rider prefers comfort or control. Lean
toward the #4 setting for comfort and toward the #3 setting
for aggressive riding.
2. For full hole adjustments, remove the 5/16" nut and flat
washers from the lower attachments of the limiter straps
and relocate the straps to the desired position (i.e. move
from position 4 to 3). Replace the nut and washer. Tighten
securely.
3. For half-hole increments (such as hole 3 or 4), the limiter
straps have slots at the upper pinch bolt. These slots allow
the bolts to be loosened (rather than removed) for half-step
adjustments. Re-tighten the pinch bolts.
4. There are also two front arm mounting holes in the slide rail
that can adjust ski pressure. The lower hole (A) increases
