Rear End of Polaris RUSH Changes the Snowmobile Forever

It’s being heralded as the future of Snowmobiling; the Polaris RUSH features the first truly progressive-rate bottomless rear suspension. The 2010 600 RUSH has a rear end designed to absorb even the toughest bumps, transferring the load to the super-rigid PRO-RIDE chassis which isolates the rider from spine tinglers. Polaris borrowed the rear suspension and mono-chrome arm of a motocross bike or ‘adventure’ motorcycle when creating the RUSH. We’re going to go out on a limb and say that the Polaris RUSH beats out the best sleds for backcounrty boarding which include the Polaris 800 Dragon RMK and the Ski-doo Summit 800R Power T.E.K.

Polaris has outfitted the RUSH with the 600cc Polaris Liberty engine and improved chassis rigidity with engine mounting to deliver more power to the ground. Polaris is the industry leader in ride and handling and with the 600 RUSH they deliver aggressive styling, weight reductions, and improved reliability. The limited production 2010 Polaris 600 RUSH will be available at local dealers beginning fall, 2009, and will be offered as part of the 2010 Polaris Snow Check program beginning in March 2009. No word on pricing yet.

“The new Polaris 600 RUSH truly marks a turning point for the snowmobile industry,” said Scott Swenson, vice president, Snowmobile Division of Polaris Industries Inc. “The progressive-rate rear suspension has been proven in Motocross; Polaris has now become the first company to bring it to snowmobiles. This innovative suspension combined with the new super-rigid PRO-RIDE chassis provides riders with an unprecedented level of rider-active control including improvements in acceleration and cornering.” How you ask? Polaris’ Pro-Ride design features a Walker-Evans piggyback ‘clicker’ main shock with adjustable coil spring that sets the sled’s ride balance front to rear. The mono-shock and its arm linkage effects front ski pressure and front to rear weight transfer under acceleration and during deceleration.

The addition of this rear suspension has us asking; where were snowmobile makers in teh ’80s when this technology was first seen in motocross bikes? But at least the technology has caught up now, and we’ll no longer have to go home sore and bruised after a day out riding in the snow.
