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 Legend 550 Snowmobile (2004)
The 2004 Ski-Doo Legend 550 was a popular snowmobile, known for its reliability. This model featured a 553.4cc (or 553cc) two-stroke, fan-cooled engine, rated at approximately 60 horsepower. For the 2004 model year, Ski-Doo offered two main trims: the Legend 550 Fan, designed for trail riding, and the Legend GT Fan 550, a touring-oriented model. Both the 2004 Legend 550 Fan and the Legend GT Fan 550 were "Carryover" models, meaning they continued from previous years without significant mid-cycle generation or engine changes for 2004. The Legend GT Fan 550 was introduced in 2001, and the Legend 550 Fan in 2002, with the Rotax 550 Fan engine remaining consistent across these models. FAQ:
