Vehicle Information
Polaris RZR 900 Side-by-Side (2014-2026)
The Polaris RZR 900 series, a popular side-by-side vehicle, has evolved significantly between 2014 and 2026. Initially, 2014 models featured an 875cc ProStar engine producing 88 horsepower. A major update occurred in 2015, introducing a new 75 horsepower 875cc ProStar 900 engine, alongside updated ergonomics and styling inspired by the RZR XP 1000. This marked a notable shift in the platform. The series saw another significant overhaul in 2021 with new bodywork and interiors for the RZR Trail and RZR Trail S models. Crucially, the RZR Trail S line diversified its engine offerings, introducing a more powerful 999cc engine with 100 horsepower for its Premium and Ultimate trims, alongside the continued 875cc 75 horsepower option for the Sport trims. These two engine choices for the Trail S models persisted through 2026, while RZR Trail models generally maintained the 875cc 75 horsepower engine. FAQ:
