Description
Bred from a rich history of experienced belt builders, the Dayco XTX belt is specifically engineered to maximize the performance of the most extreme, high horsepower snowmobiles. Beating the competition on the race course is just one of many aspects that sets the XTX belt apart from its competition. Specially formulated high temperature Polymer along with the highest level of engineered reinforcement proves to perform better in belt operating temperature and efficiency than leading competitors. Its innovative break-through design of deeper cogs on top and rounded cogs on the bottom yield the advantages of ultimate flexibility and longer belt life while being a better alternative to the original equipment belt.

Vehicle Information
Ski-Doo Mach 1 670 Snowmobile (1994-1996)
The Ski-Doo Mach 1 670, produced from 1994 to 1996, was a high-performance snowmobile powered by a consistent Rotax 670 twin engine, delivering approximately 118 horsepower in 1994. Throughout its production, the primary trim was the "Mach 1 670" or "Formula Mach 1 670," representing a top-tier offering without distinct sub-trims. A significant mid-cycle evolution occurred in 1995. The model transitioned from the PRS chassis to the more advanced F2000 chassis, bringing substantial performance and handling upgrades. These included the adoption of 44mm carburetors, factory twin pipes, hydraulic disc brakes, and an improved C7 rear suspension. The 1996 model largely maintained these specifications, notably being the last Ski-Doo snowmobile to feature factory twin pipes. FAQ:
