Screamin' Eagle 131 Performance Crate Motor

It’s the biggest, most powerful street-compliant performance engine Harley-Davidson has ever created. Built from the bottom up in Milwaukee, this street-tuned 131-cubic-inch Screamin’ Eagle^® Crate Engine is designed to run with a wide-open throttle at high engine speeds and provide instant passing power from cruising speed. Made for riders seeking maximum displacement, compression and flow, it delivers 131 ft-lb of torque to the rear wheel as soon as the throttle is cranked. This Stage IV equipped engine includes 131 Stage IV badging on the cylinder heads and timer cover to highlight the powerplant.
