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.

Polaris Sportsman X2 800 ATV (2007-2009)
The Polaris Sportsman X2 800, available from 2007 to 2009, is a versatile ATV known for its innovative two-up riding capability, thanks to a transforming seat.

This robust powertrain remained unchanged, ensuring consistent performance across the 2007-2009 range.
While the 2007 model offered "Standard" and "Deluxe" trims, the 2008 and 2009 models were primarily designated as the "Polaris Sportsman 800 EFI X2" without further sub-trims. There were no significant mid-cycle generation or engine changes reported for the Sportsman X2 800 during this period; its core features and engine platform remained consistent. FAQ:
