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
Yamaha SX700 Snowmobile (2000-2001)
The Yamaha SX700 snowmobile, including its SXR700 and SX700F variants, and the high-performance SRX700 model, defined the 2000 and 2001 model years. These 698cc triple-cylinder, 2-stroke snowmobiles offered distinct configurations. The SX700/SXR700 produced approximately 120 horsepower, while the SRX700, with its triple-piped engine and power valves, reached 142 horsepower. Notable distinctions exist between the 2000 and 2001 models. For 2000, the SRX700 received a new ignition system inspired by the R1, boosting horsepower and fuel economy, along with chassis and rear suspension enhancements. In 2001, the SXR700 featured a revised electrical system with engine-mounted ignition coils, a dual-bulb headlight, and silver trailing arms. Q : How can I ensure parts fit my Yamaha SX700?
