Vehicle Information
Polaris Sportsman 450 ATV (2006-2026)
The Polaris Sportsman 450, a versatile all-terrain vehicle, has been a staple in the ATV market from 2006 to 2026. Known for its robust performance and adaptability, this model has undergone several significant evolutions in its engine and available trims, catering to a wide range of utility and recreational needs. The model saw a major engine update in 2016 with the introduction of the Sportsman 450 H.O., which, despite its name, featured a 567cc EFI engine producing 31 horsepower, replacing the earlier 455cc carbureted unit from 2006. From 2018 onwards, the Sportsman 450 H.O. models standardized to a ProStar 499cc/500cc EFI engine, delivering 33 horsepower. Trims have consistently included a base model and an EPS (Electronic Power Steering) version, with additional enhancements like increased towing capacity and ground clearance introduced in 2020, and new features for 2026 models.
