Harley-Davidson has released a new Screamin’ Eagle Milwaukee-Eight 131 crate engine for 2018-later Softail models.

The 131 crate engine is priced from $9764, though Harley-Davidson says the additional purchase of an ECM calibration is required for a “proper” installation.

The 2151cc V-twin is capable of producing 92kW and 183Nm.

Notably, having the motor installed by an authorised H-D dealer affords customers a 12-month warranty.

Measuring 2151cc, and delivering 92kW (124hp) 183Nm (with H-D Street Cannon exhaust), the 131 crate engine is said to be the biggest, most powerful street-compliant engine that Harley has yet developed.

Distinguishing the motor is ‘Stage IV’ badging on the cylinder heads and timing cover, and the donk can be optioned in either Black and Chrome or Black and Gloss Black finishes.

Combining the 4.5-inch stroke of the 114 engine with new 4.31-inch bore cylinders, the 131 crate engine benefits from larger valves, a new high-lift camshaft, high compression (10.7:1) forged pistons, and a 64mm throttle body, among other upgrades.

The Screamin’ Eagle motor bolts into Softail models from 2018 onwards that were originally equipped with a Milwaukee-Eight engine.

Entry into the Softail range starts with the Softail Standard, which checked in earlier this year from $21,495 plus on-road costs.

The cruiser range then includes the Street Bob, Low Rider, Softail Slim, Low Rider S, Deluxe, Sport Glide, Fat Bob, FXDR, Breakout and Fat Boy.

“Our adrenaline-seeking riders asked for thrilling power and torque with reliability,” said Harley-Davidson product manager James Crean in a press release.

“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.”

In March, Harley-Davidson released a Milwaukee-Eight 131 crate engine for Touring models which is priced from $9,610 in oil-cooled guise, or $9,920 with the twin-cooled option.
