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
Ski-Doo Freestyle 550 Snowmobile (2007-2009)
The Ski-Doo Freestyle 550, produced from 2007 to 2009, was a versatile snowmobile designed for various riding styles, from trails to stunt parks. Throughout these model years, it consistently featured a robust 553.4cc fan-cooled 2-stroke engine, known for its lively performance. The introduction of the Rotax 550F engine in 2007 was a significant upgrade for the Freestyle lineup, offering a substantial boost in power compared to previous versions. This engine remained the standard across all trims, including the Freestyle Park, Session, and Back Country, with 2008 and 2009 models largely being carryovers without major mid-cycle changes. FAQ:
