For 2015, the Polaris RANGER XP 900 will feature a recalibrated, high output ProStar 900 engine that churns out 68 horsepower, a 13 percent increase, and keeps the vehicle as the class-leader in torque. New, intake openings, on the pillars behind the driver and passenger, allow for improved airflow for the engine and clutch air intake systems. For a new look, the vehicles also feature edgier headrests, and new graphics packages and colors.
