This Yamaha snowmobile nameplate was introduced for the 2008 model year as a new high-performance 4-stroke sport line built around Yamaha’s liquid-cooled inline three-cylinder engine. It marked Yamaha’s push to pair the company’s established 4-stroke snowmobile technology with a more aggressive chassis and handling package for trail and crossover riding. Early versions included both rough-trail and mountain-oriented variants, and the family quickly became known for its broad spread of applications rather than a single one-size-fits-all setup.
Over the next several model years, the nameplate evolved through a range of versions aimed at different snow conditions, including trail, crossover, and deeper-snow use. Yamaha refined the lineup with updated skis, track lengths, and suspension packages, while keeping the focus on sporty handling and the company’s 4-stroke character. The name was used on models such as R-TX, M-TX, and X-TX variants, with later updates pushing deeper-snow capability and broader performance versatility.
By the 2014 model year, Yamaha had introduced the SR Viper as the successor in this class, and the earlier nameplate was no longer carried forward. As a result, this was a single continuous production run that began in 2008 and ended with the 2014 model year.
