Description
The stock drive belt on your Ski-Doo MX Z 670 is likely leaving horsepower on the table. The Ultimax XS806 transfers power more efficiently from engine to track while resisting the heat and wear that prematurely fail OEM belts. If you’re pushing your sled hard, this belt is designed to keep up.
Built with a proprietary rubber compound and dual-cog construction, the XS806 minimizes slippage under acceleration and maintains consistent performance across extended riding sessions. The improved thermal management keeps the belt cooler under load, directly translating to better throttle response and longer service life compared to factory equipment.
