2018 Rubicon 500 IRS EPS
Efficient, durable engine design
Powerful liquid-cooled 475 cc engine is longitudinally mounted, allowing direct driveshaft alignment to both front and rear wheels for maximum drivetrain efficiency. Liquid cooling provides consistent engine operating temperature in extreme conditions for maximum power output and long engine life. Overhead-valve design provides compact engine dimensions for improved ground clearance while maintaining a broad, easy-to-use powerband. Rubber-cushion engine mounting and gear-driven counter-balancer reduce vibration.
