The Ski-Doo Mach Z is the most powerful snowmobile money can buy. From its sinister black design to its menacing Rotax 1000 SDI engine, everything about it says this is not a sled you want to pick a fight with. When the 170 horsepower engine is unleashed it leaves no doubt as to who the trail boss is. Built on the maneuverable RT chassis and shod with Pilot skis, this dominator doesn't back off a bit when it hits the switchbacks. Throw in the SC-4 rear suspension and the R.A.S. front suspension - both with high performance HPG shocks - and you get a better hole shot and razor-sharp handling at every turn.
