Vehicle Information
Polaris SKS 850 Snowmobile (2019-2021)
The Polaris SKS 850, available from 2019 to 2021, is a high-performance snowmobile renowned for its powerful 850 Patriot engine and agile AXYS chassis. This model range was designed to deliver exceptional capability on and off the trail. A significant development for this period was the introduction of the all-new 850 Patriot engine in 2019. This 840 cc, 165-horsepower engine marked a substantial upgrade, replacing previous powerplants. Throughout these years, the SKS 850 was primarily offered with 146-inch and 155-inch track lengths. While the core platform remained consistent, minor updates occurred, such as a specific engine calibration for 2020 models and a slight increase in fuel capacity for the 2021 SKS 146. FAQ:
