HARLEY-DAVIDSON’S NEW SCREAMIN’ EAGLE 131 CUBIC INCH (2147cc) CRATE ENGINE | Press Release
The Biggest, Most Powerful Street-Compliant Engine Harley-Davidson Has Ever Created
Harley-Davidson offers power-hungry street riders a new performance option with the introduction of the Screamin’ Eagle® Milwaukee-Eight® 131 Crate Engine for Touring model motorcycles. The new 131 cubic inch (2147cc) V-Twin delivers the biggest, most powerful street-compliant* engine Harley-Davidson has ever created. The Screamin’ Eagle 131 is a bolt-in replacement for 2017-later model Harley-Davidson Touring motorcycles originally equipped with a Milwaukee-Eight Oil-Cooled or Twin-Cooled™ engine, designed to run at high RPM and provide a significant boost of torque from cruising speed. Riders of many late-model Harley-Davidson Touring motorcycles will experience commanding performance from the moment the throttle is cracked open on the Screamin’ Eagle 131 engine.
“Our adrenaline-seeking riders asked for thrilling power and torque with reliability,” said Harley-Davidson Product Manager James Crean. “The Screamin’ Eagle 131 Crate Engine delivers exactly that. Developed by the Screamin’ Eagle performance team and factory-assembled at Harley-Davidson Powertrain Operations to ensure the highest quality standards, this high-performance engine is genuine Harley-Davidson.”
This street-ready performance engine features H-D’s finest Screamin’ Eagle components. The Screamin’ Eagle 131 engine combines the 4.5-inch stroke of the Milwaukee-Eight 114 engine with new 4.31-inch bore cylinders with a patented design. Milwaukee-Eight Extreme Ported four-valve cylinder heads are CNC-ported and fitted with 1mm larger-diameter valves to optimise air/fuel flow and velocity and feature fully machined combustion chambers shaped to optimise combustion efficiency. The engine is completed with a high-lift SE8-517 camshaft and high-performance cam bearing, high-compression (10.7:1) forged pistons, a 64mm throttle body and intake manifold, and high-flow (5.5-grams per second) fuel injectors. It’s a combination that produces 131 ft-lb of torque and 121 horsepower at the rear wheel.
Each Screamin’ Eagle 131 engine is detailed with 131 Stage IV badging on the cylinder heads and timer cover. The engine is available in a choice of two finish treatments to match original motorcycle styling or a custom direction – Black and Chrome or Black and Gloss Black. There are also versions of the engine to fit motorcycles originally equipped with an oil-cooled Milwaukee-Eight engine and those equipped with the Twin-Cooled™ Milwaukee-Eight engine. The Screamin’ Eagle 131 engine is eligible for Custom Coverage under the motorcycle’s factory 24-month vehicle limited warranty when dealer-installed by an authorised H-D Dealer within 60 days of vehicle purchase and is otherwise backed by a 12-month limited warranty.
