Öhlins Apex RTX Mounting Instructions

Recommended Rear Ride height
- Pro Action suspension
With rider on the snowmobile, wearing all riding
gear, we recommend the coupling adjuster free
play to be equal in both directions (see fi gure to
the right), assuming that the coupling adjuster
is in its standard setting.
Increase or decrease the spring preload until
you have reached the middle position of the
coupling adjuster.
If you carry heavy luggage, or a passenger on a
2-seater, you will need to do these adjustments
under these specifi c conditions.
Mono Shock suspension
Raise the rear end of the snowmobile slightly,
but only until the drive track barely lifts off the
ground. On the running board, mark with a pen
just above the rear axle. Measure the distance
from the marking on the running board to the
ground (D1).
With a rider on the snowmobile, measure the
distance from the same marking on the running
board to the ground (D2).
Recommended rear ride height:
D1 - D2 = approximately 65 mm / 2.5 "
NOTE!
The spring pre-load affects the ride height – it
does not affect bottoming.
You may need to increase the rebound damping
slightly when using more spring pre-load than the
delivered setting.
If you experience the suspension bottoming
out too often, do not increase spring pre-load.
Your ride height might make your coupling
adjuster run out of the range described above,
thus creating a harsh ride. Instead, change to a
stiffer spring and adjust your spring pre-load as
described above.
If you experience that the suspension is too stiff,
do not decrease spring pre-load. It will not fi x your
problem, and your ride height might make your
coupling adjuster run out of the range described
above, thus creating a harsh ride. Instead, change
to a softer spring and again adjust your spring
pre-load as described above.
