2021 Ski-Doo MXZx 600RS E-TEC

Ski-Doo has been kicking butt and taking names the last couple of years in snocross racing. Elias Ishoel has shown his incredible talent by taking the Pro titles the last two seasons, but the strength of Ski-Doo’s race program can be seen much deeper, as its racers in most classes get to the first corner first and then stay ahead and win races and championships. Combined, Ishoel in Pro, Francis Pelletier in Pro-Lite and Megan Brodeur in Pro-Women created a Ski-Doo sweep of the Pro classes on the ISOC Amsoil Championship Snocross circuit last season. 

Looking to build on that momentum, Ski-Doo is making a few notable changes to its 2021 MXZx 600RS race platform for the 2021 racing season while the other brands take bigger swings trying to catch up.

Most important are new shocks in the front suspension of that race sled. Ski-Doo is now opting for Kashima-coated 46mm KYB Pro Series shocks as standard equipment above the skis after opting for smaller bore 40mm KYBs last year.

The new shocks will feature the same integral base value system as last year that allows for easy external adjustment of high- and low-speed compression rates as well as high-speed rebound, utilizing screws instead of clickers. Many of Ski-Doo’s top drivers on its “Super Teams” used these shocks last year; by making them standard equipment for 2021 now all Ski-Doo racers can benefit from the more controllable travel and expanded capacity.  

“Suspension calibration has changed to match the new shocks with the rest of the chassis and is based on direct rider feedback to further handling benefits,” Ski-Doo said in a press release. New calibrations are also found in the Racing rMotion rear suspension, which returns with 46mm KYB Pro Series shocks.

Between the side panels, new calibrations on the 600RS E-TEC engine were aimed at dialing in better holeshots off the starting line as well as crisper mid-range power, Ski-Doo says. Returning features include E-TEC direct injection, double reed valves, intake booster injectors and plasma-coated cylinders.

The rest of the driveline stays the same – including pDrive primary and TEAM TSS-04 secondary clutches and a slip-gear in the chaincase, with a large diameter Brembo brake providing stopping power. Ergonomics on the REV Gen4-based race sled are unchanged as well. The only other alteration is a new taillight.

Normally when Ski-Doo announces its race sled at the annual Hay Days Grass Drags & Swap Meet, it also unveils its complete race teams. However, like the other brands so far, that information isn’t being released quite yet. Stay tuned into SnowGoer.com – we’ll release that information as soon as it becomes available.
