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
Yamaha SR Viper STX 1050 Snowmobile (2015-2017)
The Yamaha SR Viper STX 1050, produced from 2015 to 2017, is a high-performance snowmobile known for its reliable 1049cc Genesis 4-stroke engine. Although the model name includes "1050," the actual displacement is 1049 cubic centimeters, consistently delivering around 130 horsepower. This engine platform remained unchanged throughout these model years; the 998cc turbo engine, for instance, was introduced in the separate Sidewinder line, not as an update to the Viper. While the core engine remained constant, Yamaha introduced significant refinements and trim-specific updates each year. In 2015, a Viper-exclusive Tuner dual runner ski improved handling, and Limited Edition (LE) models received upgraded shocks. The 2016 lineup saw the S-TX platform split into 137-inch and 146-inch versions, with suspension adjustments across the range and Performance Dampers on many LE models. For 2017, models like the R-TX SE and L-TX SE received new coil-over Fox shocks, and spring-available L-TX LE models featured upgraded Fox Zero QS3 Kashima shocks, ensuring continuous performance enhancements.
