REAR SUSPENSION
SETTING 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 Fusion (700/900) = 2” (5cm)
• IQ Fusion (600) = 4-5”(10-13cm)
• IQ RMK = 5” (13cm)
• IQ M-10 = 3-4” (8-10cm)
• Switchback = 5” (13cm)
• EDGE RMK/EDGE = 4” (10cm)
• EDGE M-10 = 3-5” (8-13cm)
• Widetrak = 1.5” (4cm)
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 can not 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.
SCISSOR STOP ADJUSTMENTS
The RRSS controls weight transfer from the rear suspension
to the skis. It also influences the stiffness of the ride by
controlling the amount of coupling action between the front
and rear torque arms. To decrease weight transfer, the RRSS
should be set in the high position.
The RRSS can be totally removed for maximum weight
transfer. However, unless the torsion springs and rear shock
valving are changed, the ride will be compromised. Always
maintain equal adjustment on both sides.
To adjust the scissor stops place the scissor tool onto the
scissor block and turn to the desired position. Ensure that the
rear scissor stop face is square with the face of the scissor arm
to ensure complete contact.
