Harley-Davidson Unleashes 131-inch Screamin Eagle Crate Motor

Milwaukee Scream Team

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, performance backed by the assurance of a factory limited warranty.

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 optimize air/fuel flow and velocity and feature fully machined combustion chambers shaped to optimize 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 when paired with Screamin’ Eagle® Street Cannon mufflers.

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 authorized H-D Dealer within 60 days of vehicle purchase, and is otherwise backed by a 12-month limited warranty.
