Vehicle Information
Ski-Doo Backcountry 850 Snowmobile (2019-2026)
The Ski-Doo Backcountry 850, produced from 2019 to 2026, is a crossover snowmobile designed for both trail and deep snow riding. It is powered by the potent 849 cc Rotax 850 E-TEC engine, delivering 165 horsepower. Over the years, the lineup has evolved with enhanced platforms and engine options. Initially built on the REV Gen4 platform (2019-2022/2023), the Backcountry gradually adopted the REV Gen5 platform starting in 2023, becoming widespread by 2025-2026. This transition brought a refined design, improved handling, and modern features such as LED headlights and 10.25-inch touchscreen displays on some models. A significant advancement is the introduction of the 180 hp Rotax 850 E-TEC Turbo R engine, available for the Backcountry X-RS from 2025. Suspension systems were also enhanced, with the arrival of RAS X and RAS RX front suspensions, and the cMotion X rear suspension, for increased performance across all terrains. Key trims include the base Backcountry, Adrenaline, X, and X-RS. FAQ:
