SCREAMIN' EAGLE 135CI STAGE IV 
PERFORMANCE CRATE 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.
