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 RX1 1000 Snowmobile (2003-2005)
The Yamaha RX1 1000 snowmobile, produced from 2003 to 2005, is renowned for its powerful 998cc "Genesis Extreme" 4-stroke, 4-cylinder engine, delivering 140-150 horsepower. This model was offered in various trims, including the standard RX-1, the deep-snow oriented RX-1 Mountain, the RX-1 Warrior with its longer 136-inch track (from 2004), and the RX-1 ER featuring electric reverse (in 2005). While the core engine remained consistent, Yamaha implemented significant mid-cycle updates. The 2003 models experienced piston ring issues, which were addressed with improved rings and a breather tube modification in 2004, with further ring changes in 2005. Fuel system updates in 2004 prevented starvation on inclines. A major suspension change occurred in 2005, replacing the "Proaction SXV" (2003-2004) with the "Mono Shock RA" rear suspension, offering enhanced ride quality, though early 2005 Mono Shock models had some vulnerabilities. These updates mean that parts compatibility can vary between model years. FAQ:
Q: How do I ensure I select the correct parts for my Yamaha RX1 1000?
