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 RZR XP 4 900 Side-by-Side (2012-2013)
The Polaris RZR XP 4 900, available for the 2012 and 2013 model years, is an extreme-performance side-by-side designed for thrilling off-road adventures. Both years were powered by a robust 875cc ProStar 900 EFI Twin engine, delivering a strong 88 horsepower. This engine featured Dual OverHead Cams (DOHC), four valves per cylinder, and dual throttle bodies, ensuring responsive acceleration and consistent performance across the range. While the core engine displacement and horsepower remained consistent, the 2013 model year introduced a significant internal engine change: Polaris transitioned the oiling system from a dry sump to a wet sump setup. Other notable enhancements for 2013 included easier shifting out of park and a new flat rear cargo box for increased storage. Trims for both years offered premium features; for instance, the 2012 Liquid Silver LE and 2013 Limited Edition models often included Electronic Power Steering (EPS), Maxxis Bighorn tires on 12-inch aluminum rims, and distinctive aesthetic packages. A specialized 2013 RZR XP 900 H.O. Jagged X Edition, though a two-seater, featured a 94-horsepower engine and performance upgrades. FAQ:
