That’s 2151 cubic centimeters to you and me, and maybe the biggest engine out there after the Triumph Rocket 3, no? That’s 14 ci bigger and/or 234 cc larger than the biggest M8 you can get in any production Hog. It’s good for 135 ft-lb of torque and 124 HP at the rear wheel, says Harley, when paired with Screamin’ Eagle Street Cannon mufflers. A nice little upgrade to your 2018 and later Softails that came with a M8.
Harley-Davidson Press Release:
NEW SCREAMIN’ EAGLE 131 CRATE ENGINE OFFERS BIG POWER FOR SELECT HARLEY-DAVIDSON SOFTAIL MOTORCYCLES
The Biggest, Most Powerful Street-Compliant Engine Harley-Davidson Has Ever Created Now Available for Select Softail Models
MILWAUKEE (August 25, 2020) – Harley-Davidson offers power-hungry street riders a new performance option with the introduction of the Screamin’ Eagle Milwaukee-Eight 131 Crate Engine for select Softail model motorcycles. The new 131 cubic inch (2151cc) V-Twin engine delivers the biggest, most powerful street-compliant engine Harley-Davidson has ever created.*
The Screamin’ Eagle 131 is a bolt-in replacement engine for select 2018-later model Harley-Davidson Softail motorcycles originally equipped with a Milwaukee-Eight engine, designed to run at high RPM and to provide a significant boost of torque from cruising speed. Riders 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 12-month factory limited warranty when installed by an authorized H-D dealer.
“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 patent-protected design.
- Milwaukee-Eight Extreme Ported four-valve cylinder heads are CNC-ported and fitted with valves 1mm larger in diameter than the previous generation to enhance 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 135 ft-lb of torque and 124 HP 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.
The Screamin’ Eagle 131 engine is eligible for Custom Coverage Extended Limited Warranty to run concurrent with the remainder of the motorcycle’s factory 24-month manufacturer’s warranty. The engine must be purchased and installed by an authorized H-D Dealer within 60 days of vehicle purchase to qualify for the Custom Coverage and is otherwise backed by a 12-month factory limited warranty when installed by an authorized H-D Dealer.
