Harley-Davidson to Offer New Screamin’ Eagle 131 Crate Engine

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.

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 is 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. The Screamin’ Eagle 131 engine is backed by the assurance of a factory limited warranty.

This street-ready performance engine features H-D 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.-lbs. 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.
