Tear it up on the Ski-Doo MX Z ($10,200). This snowcross race sled is available with one of three liquid-cooled engines — the 600 H.O. E-TEC, 800R Power T.E.K. or 1200 4-TEC — and packs in a whole ton of special equipment you and us have never heard of. Stuff like Kayaba HPG Clicker Take-Apart aluminum front and rear shocks, a 1.25-inch lug RipSaw track, Pilot 5.7 skis, and a REV-XP racing seat. Regardless, this machine was born to shred.
