Vehicle Information
Polaris Sportsman SP 850 ATV (2015-2019)
The Polaris Sportsman SP 850, produced from 2015 to 2019, is a robust all-terrain vehicle known for its powerful performance and versatility. Throughout these model years, it consistently featured an 850cc ProStar SOHC 4-Stroke Twin Cylinder engine, delivering a strong 78 horsepower. This engine was equipped with Electronic Fuel Injection (EFI) and liquid cooling, ensuring reliable operation across various conditions. While the core engine platform remained consistent, Polaris introduced several refinements and trim variations during this period. The "SP" designation typically indicated a premium package, often including features like power steering, Engine Braking System (EBS) with Active Descent Control (ADC), and upgraded wheels. "Touring" models were designed for two riders with a longer wheelbase, and the "High Lifter Edition" (introduced around 2017) was specialized for mud riding. For 2019, the Sportsman 850 models received notable upgrades, including a larger battery for improved starting and accessory power, enhancements to the adaptive electric power steering, and clutch improvements for quicker engagement. The Engine Braking System also saw refinements for smoother deceleration. These were mid-cycle improvements rather than a full generation change. FAQ:
