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 Formula Mach 1 670 Snowmobile (1993)
The 1993 Ski-Doo Formula Mach 1 670 was a prominent snowmobile of its era, recognized for its powerful 669cc (often rounded to 670cc) liquid-cooled twin engine, which produced approximately 118 horsepower. This engine, a Rotax 670 RAVE, positioned the Mach 1 as a high-performance option for enthusiasts. The 1993 model year brought significant updates to the Mach 1. The engine displacement increased from the 617cc used in previous models (1991-1992) to the more powerful 670cc unit. This year also saw the introduction of an upgraded C-7 rear suspension and a wider 40-inch ski stance, enhancing control and stability. While the Mach Z became Ski-Doo's new top-tier performance snowmobile, the Mach 1 remained a strong contender. Two trims were available: the standard Formula Mach 1 670 and the Formula Mach I XTC, designed for enhanced trail versatility and performance. Q: How do I ensure this product fits my 1993 Ski-Doo Formula Mach 1 670?
