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 340 Snowmobile (2008)
The 2008 Polaris 340 series is a snowmobile known for its reliable 339cc, 2-stroke engine. This model year offered several trims, including the INDY 340 LX, 340 Transport, 340 Touring, and 340 Deluxe, catering to various rider needs. All 2008 models shared the same 339cc horizontal in-line engine, featuring reed valve induction and carburetor-based fuel delivery. While the core engine and platform remained consistent for the 340 series in 2008, the 340 Transport was introduced as a new trim for this model year, expanding the lineup. Other general updates across Polaris's broader snowmobile range in 2008, such as new spindles for IQ sleds, were not specifically tied to mid-cycle generation changes for the 340 series itself. FAQ:
