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 Skandic 377 Snowmobile (1982-1987)
The Ski-Doo Skandic 377, produced from 1982 to 1987, is a robust utility snowmobile designed for work and trails. It was consistently powered by the Rotax 377 engine, a 368.3 cc two-stroke, fan-cooled twin-cylinder engine producing 35 horsepower (26 kW). This reliable engine maintained its technical specifications throughout this production period. While the engine remained consistent, the Skandic 377 was offered in various trims, including the base model and the more utility-focused Skandic 377R. The 'R' models were distinguished by enhanced features such as a chain drive system, a reinforced chassis, and often a longer track. For instance, the 1986 377R had a 139-inch track, compared to 136 inches for the 1982 377. These 'R' versions also incorporated specific mechanical differences like a parking brake lever, a gear shift lever for forward/reverse operation, and a self-adjusting brake system, thus offering increased capabilities for utility tasks.
