Last year the MXZx-600RS debuted on the all new REV-XP platform. For 2009 the Valcourt Engineering and Race Shop team has made dozens of improvements which Ski-Doo says will enhance rider control, handling, suspension and durability.

“Our goal was to make the snowmobile easier to race – for both the driver and their mechanics,” says Ski-Doo director of marketing Francois Tremblay. “The changes reflect our priorities of easier handling, better cornering and better suspension at race speeds – along with the need for extreme durability to keep racing costs lower.

“Many of the changes were also the result of direct feedback from X-Team racers and mechanics, from SuperTeams to the grassroots.”
