Riders seeking the ultimate in straight-line thrills need look no further than the Ski-Doo Mach Z snowmobile. It's easy to find — just check the winner's circle. The intimidation begins beneath the hood, with the largest Rotax engine on snow — a 796cc, liquid-cooled, three-cylinder legend. Thanks to our exclusive R.A.V.E. technology, it sports an unmatched combination of low- and mid-range torque. Flat-slide TM-38 carbs deliver split-second throttle response while triple-tuned pipes provide a broader power band at the top of the rev range.
