In a partnership with Arctic Cat (now owned by Textron), Yamaha Motor Company supplies the 1,050cc 3-cylinder (135+ HP) and 998cc 3-cylinder turbocharged (180+ HP) engines for use in a collaborative chassis sold under each brand name. While there are similarities between the respective manufacturers' models, small differences can be noted. SR Viper (Arctic Cat 7000-series equivalent) and SideWinder (Arctic Cat 9000-series equivalent) models are equipped with Yamaha clutches and changes to certain plastic body panels (such as the color, suspension set-up, windshield and intercooler housing on turbocharged models). The suspension layout, chassis, gauge package, and handlebar switchgear remain the same between both brand's snowmobiles. This partnership was established for the 2014 model year with the introduction of the 2014 SR Viper and Arctic Cat 7000-series line-up.
