16200977 For the rider demanding 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 144 horsepower and 149 ft-lb of torque to the rear wheel. The 135ci engine compression ratio is 11.6:1. Exclusive 135 and Stage IV badging on the cylinder heads and timer cover highlight the powerplant. This street-ready performance motor features the finest Screamin' Eagle components. Many of these new components were informed by extensive testing by the Harley-Davidson Factory Racing Team for the King of the Baggers racing series. The 135ci Crate engine consists of: all-new Screamin' Eagle Extreme CNC-ported cylinder heads, new SE8-550 high-lift cam, new high-compression forged pistons, 68mm throttle body and new CNC-machined Extreme Flow 68mm intake manifold, high-performance cam bearing, high-performance tappets, new patent-protected 4.31" steel sleeve cylinders, 4 5/8" flywheel, 6.8 g/sec fuel injectors, and Screamin' Eagle Pro Billet Cam Plate and Oil Pump. Black Granite / Chrome finish. Engineered and tested as a complete collection of high-performance components by the Screamin' Eagle pros at Harley-Davidson. This combination is designed for wide open throttle along with high end RPMs and a significant torque increase from a cruising speed. Ready for bolt-in installation in the Original Equipment-style chassis of your Touring bike. For models originally equipped with Variable Valve Timing (VVT), VVT will not be retained with this performance crate engine. No special fabrication or engine-mount relocation is required. Factory assembled at the Powertrain Operations facility in Milwaukee, Wisconsin.
