REAR SUSPENSION ADJUSTMENTS
Adjustment Procedures
NOTE: Break-in the suspension for at least 150
miles (240 km) before making adjustments.
All settings will vary from rider to rider, and are dependant on
rider weight, vehicle speed, riding style, and trail conditions.
Always start with the factory settings. Make individual
adjustments to suit rider preference. The machine should be
methodically tested under the same conditions after each
adjustment (trail and snow conditions, vehicle speed, riding
position, etc.) until a satisfactory ride is achieved. Adjustments
should be made to one area at a time, in order to properly
evaluate the change.
Rear Suspension Ride Height
1.
To set up the rear suspension torsion spring preload,
measure the distance between the ground and rear bumper
with out the rider on the seat and the suspension at full
extension. This can be achieved by lifting the rear of the
machine so that the suspension is off the ground and
carefully setting the machine down. Write this down as
measurement "X".
2.
Have the rider in full gear drop down on the seat, work the
suspension slightly by bouncing up and down and sit in the
seated riding position. With the rider in the seated position
measure from the ground to the bumper in the same spot as
you did for measurement "X" and write it down as
measurement "Y".
3.
To determine the correct ride height, subtract measurement
X from measurement Y. (X - Y = ride height).
4.
The ideal ride height is:
• IQ 121 / 136 = 4-5"(10-13cm)
• IQ RMK / Switchback = 5" (13cm)
• IQ M-10 = 3-4" (8-10cm)
5.
Adjust for the desired ride height by rotating the torsion
spring cams located on the rear of the torsion spring.
If the rear suspension ride height cannot be adjusted to the
correct dimension, optional torsion springs may be required.
This is only an initial setup, and final spring preload may vary
based on rider preference and riding conditions.
Steering and Suspensions

Scissor Stop Adjustment
The front rear scissor stop (FRSS) controls the bump attitude of
the rear suspension. As the front torque arm (FTA) hits the
bump, it forces the rear scissor to collapse a predetermined
amount, depending on the FRSS block position.
This accomplishes two important things. First, it allows a lighter
spring rate on the FTA because it can borrow spring rate from the
