BRP introduces 2010 Ski-Doo MXZx-600RS
Racing sled revised and refined for 2010
BRP introduced the 2010 Ski-Doo MXZx-600RS at Hay Days. The MXZx-600RS has a host of changes and refinements designed to improve performance in all aspects of racing and take X-Team riders to more wins this season.
Ski-Doo had success with the sled last year in snocross and cross country racing, but he Valcourt Engineering and Race Shop team wanted to take things even further. For 2020 improvements concentrated on stronger engine and hole shot performance, better chassis control in bumps and turns and improved ergonomics for the racer – all designed to reduce lap times, and take less effort from the driver.
“This year we worked hard on Holeshot, engine performance, suspension and chassis stability” says Denis Morin, Ski-Doo vice president of engineering. “The changes will result in better starts, more consistent engine and clutch performance through a long race and a chassis that is easier to ride at race speeds.”
2010 Ski-Doo MXZx-600RS“Our racers gave us great feedback and we acted on their information” added Jeff Goodwin, Ski-Doo race manager. “Almost all components are recalibrated for better performance in every condition, especially suspension.”
