SUSPENSION PART 4: SKI-DOO rMOTION

- Advertisement -

Amazingly, Ski-Doo’s rMotion, a suspension we personally feel is at the top of the heap for ride compliance, is not about trick attachments or gimmicks.

This rather conventional two shock-in-skid setup doesn’t possess a lot of breakthrough Ski-Doo-only technology but is calibrated and designed so precisely it works amazingly well for all types of riders and riding styles.

rMotion is a coupled, dual arm skidframe using a coilover shock on the front arm and torsion springs at the rear. There’s a long front arm with a high lower mounting point on the rail.

At the extreme rear, the coupler blocks (originally Polaris and FAST tech) are adjustable by rotating them and there are two torque links (originally Arctic Cat tech) used to control track deflection and optimize bite under acceleration.

Rate changes can be adjusted with a linkage that provides varied mounting positions for the lower mount of the rear shock.

Yes, there are various remote adjustable options if you pay for them, for tuning spring and damping rates from the drivers seat. This is a nice touch but truly, not critical to the way the skidframe functions.

The biggest deal with rMotion is how it has taken basic available technology and precision calibrated it to produce incredible ride results.

If we could say anything about it to turn the spotlight on Ski-Doo, we would mention that rMotion’s long arm tech (now used by everyone else) was first out of the gate.
