2011 Ski-Doo MXZx 600RS Preview

BRP is coming off its most successful snocross racing season in years, but that hasn’t stopped the manufacturer from redesigning its race sled for 2011. The 2011 Ski-Doo MXZx 600RS will feature more horsepower and a completely new rear suspension.

Despite the success seen on the 2010 race sled – like Tim Tremblay taking the ISOC Pro Stock National Sno-Cross series title, Lee Butler winning Pro Stock in CSRA, plus multiple wins and championships in Semi-Pro and Sport classes across all venues – the Engineering team in Valcourt, Que. has stepped up with major improvements for 2011.

“In racing you never stop developing your product, and because winning is part of our heritage at BRP, you can expect that we would continue to improve the MXZ race sled to be much better than last year” says Denis Morin, vice president of engineering for BRP. “The changes will provide better starts and more speed along with a very controlled ride tailored specifically for race conditions.”

According to BRP, the MXZx 600RS engine will come with new cylinders and a new combustion chamber shape to significantly improve power at all RPM’s. BRP says racers will see better acceleration, stronger mid range response and more top end power as a result of these changes – which is designed to lead directly to better holeshots and better pull out of the turns. The clutch calibration has changed substantially to make sure the extra power is delivered to the track, along with quick back shifting and instant throttle response.

This SC-5 rear suspension has been replaced by the new PCX system for 2011.

The rear suspension is completely new this year. Dubbed PCX, this new skid frame is intended for race use only. The PCX features a stronger re-designed coupling system, new shock motion ratio geometry and the built in durability a racer demands. In addition to taking the big hits of jumps and bumps, the PCX was designed to deliver better cornering and better holeshots by controlling the chassis pitch more thoroughly throughout the travel, along with improving the sled’s cross country capability.

“We’re really excited about the changes for 2011” says Jeff Goodwin, Ski-Doo race manager. “The new suspension has been a huge step forward and will really make a difference for the racers in all conditions. Combine that with the extra engine power to assure great holeshots and we have a great race sled for next season that will be hard to beat.”

Unfortunately, Ski-doo won’t be releasing any more information or images related to the 2011 MXZx 600RS until September.

Racers have until May 1, 2010 to complete an application (available on line on the X-Team home page) for the new MXZx 600RS. There will also be Race Schools conducted this fall to support racers on the new sled. Be sure to check Ski-Doo.com in mid-September for more information.
