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
Polaris Pro X 700 Snowmobile (2004)
The 2004 Polaris Pro X 700 was a high-performance snowmobile designed for enthusiasts seeking power and agility. It featured a robust 700cc liquid-cooled, horizontal in-line, 2-stroke engine with reed valve induction, delivering strong acceleration on the trails. For the 2004 model year, Polaris introduced several key enhancements to its Liberty engines, including the 700cc unit in the Pro X. These updates included a Variable Exhaust System (VES) and Grafal-coated pistons for improved durability and performance. The 700cc engine also benefited from a compression release feature, reducing starting effort by up to 35%, and Detonation Elimination Technology (DET) to protect against poor fuel quality. Cooling was significantly improved with a redesigned coolant flow and a new water pump gear, increasing coolant movement by 40%. A new "low pin" clutch was also added to smooth takeoff and prevent track spin. Beyond the standard Pro X 700, Polaris offered the Pro X2, a distinct trim sharing the same chassis but featuring a higher and more forward-positioned seat, Walker Evans shocks, lightweight components, handguards, and a 1.25-inch track for an even more aggressive riding experience. The 700cc engine was available in both the Pro X and Pro X2 models, offering riders choices based on their performance preferences. FAQ:
