For the rider demanding for no-compromise performance. This is the most displacement, and the most power, ever created by Harley-Davidson for a street-compliant crate performance engine. Engineered by the pros at Harley-Davidson and built from the bottom up in Milwaukee, this street-tuned 135-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 143 ft-lb of torque to the rear wheel as soon as the throttle is cranked. Stage IV equipped engine includes 135 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: Screamin' Eagle® Extreme CNC-ported cylinder heads, SE8-517 high-lift cam, new high-compression forged pistons, high-performance cam bearing, high-performance tappets, patent-protected 4.31" steel sleeve cylinders, new 4 5/8" flywheel, new 68mm throttle body and CNC-machined 68mm intake manifold, new 6.8 g/sec fuel injectors, and Screamin' Eagle® Pro Billet Cam Plate and Oil Pump.
