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.
