Leave other riders in the dust with the biggest, most powerful street-compliant crate 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. Stage IV equipped engine includes 131 Stage IV badging on the cylinder heads and timer cover to highlight the powerplant. This street-ready performance motor features the finest Screamin’ Eagle components: engraved CNC-ported cylinder head with CNC-machined chamber and 1mm larger valves, SE8-517 high-lift cam, high-compression forged pistons, high-performance cam bearing, high-performance tappets, patent-protected 4.31" steel sleeve cylinders, 64mm throttle body and cast manifold and 5.5 g/sec fuel injectors.

These performance parts are 49-state U.S. EPA compliant but are NOT compliant for sale or use in California on pollution-controlled motor vehicles.
