Ski-Doo has released today, information about a brand new suspension that will appear on select 2012 models. The new suspension, called the rMotion, is similar in appearance to the SC-5, but it is all new with all new parts. This new skid promises to set a new industry standard for travel, rising-‐rate motion ratio and adjustability. It also has an even broader sweet spot than the SC-‐5.
The rising-‐rate motion ratio is the most progressive in the industry, keeping the skid supple in small bumps and extremely capable in large ones. The new rMotion has 13% (2 in./5 cm) more rear travel than the SC-‐5 and up to 30% more than most of the 2011 competition. This not only means extra capacity to absorb even bigger bumps, but that the springs can be calibrated softer to enhance comfort in ripples.

Ski-Doo rMotion Suspension
Separating the spring and shock motion ratios allows independent tuning of each component. In the early part of the suspension travel the rMotion uses the spring mainly to absorb stutter bumps; as the suspension moves faster and farther when the bumps get bigger, the shock plays a bigger role to absorb the bigger moguls.
The rMotion offers many easy tuning choices for those with the desire and know-‐how to fine-‐tune their ride for conditions or their riding style. All three springs have preload adjustments. The rear shock has two mounting points to change motion ratios (one biased towards a sport ride, the other towards higher performance). The inverted rear shock means the damping speed adjustment is more easily accessible. The damping speed adjustment and coupling block position (to control transfer) were redesigned so that adjustments can be made without tools and with gloves on.
rMotion Quick Adjust
For a Spring option, Ski-Doo offers the rMotion Quick Adjust System. Available only on MX Z X and X-‐RS sleds, the Quick Adjust system places controls for rear spring preload and rear shock damping speed on the running boards, with a large control knob that can be used with gloves. Their control knobs are large for operation with gloves on. With the Quick Adjust system, spring preload adjustment range is clearly marked, with infinite settings between full soft and full hard.
For 2012, the rMotion is equipped on the Spring-‐Only MX Z X-‐RS and MX Z X-‐package models. For more information, contact your Ski-Doo dealer.
