Crazy Mountain Motorsposrts, makers of the Crazy Mountain Xtreme deep-snow specialty sleds, continue to refine their CMX Belt Drive system that eliminates the heavy rotating mass of metal gears and link-style chains. The lightweight Gates Polychain cogged belt and cogged pulleys provide the gear reduction needed, and do so with incredible reliability. The massive weight reduction (rotating mass) allows for quicker acceleration, and that means track speed for climbing higher and further up the hill. Standard issue on all Crazy Mountain Xtreme mountain sleds, conversion kits are offered for select OEM mountain sleds as well. Contact Crazy Mountain Motorsports at 406-686-4921 or visit crazymtn.com.
