Vehicle Information
Polaris RZR 4 900 Side-by-Side (2014-2018)
The Polaris RZR 4 900, a robust side-by-side vehicle, was produced from 2014 to 2018. It features an 875cc ProStar 900 4-Stroke DOHC Twin Cylinder engine. Initially, the 2014 model offered 88 horsepower. From 2016 onwards, the power output was adjusted to 75 hp, a notable change in engine performance. In 2018, a significant evolution occurred with the model designation shifting to RZR S4 900 EPS. This "S4" version typically indicates a wider stance and enhanced suspension components, such as Fox Podium shocks, providing improved handling and increased off-road capabilities. While trims and color options varied over the years, the core platform remained consistent. FAQ:
