The Screamin’ Eagle 131 engine combines the 4.5-inch stroke of the Milwaukee-Eight 114 engine with new 4.31-inch bore cylinders. Milwaukee-Eight Extreme Ported four-valve cylinder heads are CNC-ported and fitted with 1mm-larger-diameter valves and feature fully machined combustion chambers.Harley-Davidson

Harley-Davidson is always keen to respond to input from its loyal consumer base, and in an effort to answer their demands for a more powerful option to the popular late-model touring bikes, The Motor Company has announced it will be offering a new 121-hp Screamin’ Eagle 131ci (2,147cc) Crate Engine.

These more powerful, high-revving lumps can be easily swapped out in any 2017 or newer Touring model equipped with the Milwaukee-Eight oil-cooled or Twin-Cooled engines.

“Our adrenaline-seeking riders asked for thrilling power and torque with reliability,” Harley-Davidson Product Manager James Crean said. “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 is the Screamin’ Eagle Milwaukee-Eight 131 Crate Engine in Black and Chrome. Both engines feature a high-lift SE8-517 cam and high-performance cam bearing, high-compression (10.7:1) forged pistons, 64mm throttle body, intake manifold, and high-flow fuel injectors. All of that comes to a head in the form of 131 pound-feet of torque and 121 hp at the rear wheel when paired with Screamin' Eagle Street Cannon exhaust.Harley-Davidson

If this sounds like an upgrade you’re willing to perform, you’ll be happy to hear the Screamin’ Eagle Milwaukee-Eight 131 Crate Engine runs $6,195 for the oil-cooled version, and $6,395 for the Twin-Cooled. The Screamin’ Eagle Milwaukee-Eight 131 engine will be available in two finish options as well: Black and Chrome or Black and Gloss Black. However, it will not fit any H-D Trike models
