UPDATE: Harley-Davidson Australia has confirmed that the Milwaukee-Eight 131 will be available locally from March, 2020.
The crate engine is priced from $9,610 in oil-cooled guise, or $9,920 for the twin-cooled option.
According to a press release, the 131 does not fit trike models and installation may require the separate purchase of additional components, depending on the model.
Also, “proper installation” requires the additional purchase of ECM recalibration and a Screamin’ Eagle Pro Street Tuner, according to Harley-Davidson.
23/01/2020: The biggest road-legal Harley donk produces a maximum of 90kW and 177Nm.
Harley-Davidson has introduced a new 131 cubic-inch (2147cc) V-twin, which is said to be a bolt-in replacement motor for Touring models.
The Screamin’ Eagle Milwaukee-Eight 131 will fit 2017-onwards bikes, and is available in both oil-cooled and twin-cooled configuration.
In the United States, where the new crate engine has already launched, it is priced from $A9000, or $9300 for the twin-cooled option.
The Screamin’ Eagle 131 engine combines the 4.5-inch stroke of the Milwaukee-Eight 114 engine with new 4.31-inch bore cylinders.
It is completed with a high-lift camshaft and high-performance cam bearing, high-compression (10.7:1) forged pistons, a 64mm throttle body and intake manifold, and high-flow fuel injectors.
Combined with a set of Street Cannon mufflers, the Milwaukee-Eight 131 delivers a claimed 90kW and 177Nm to the rear wheel.
The donk features ‘Stage IV’ badging on the cylinder heads and timing cover, and can be finished in Black and Chrome, or Black and Gloss Black.
In Australia, the 2020 Harley-Davidson Touring range includes the Road King, Electra Glide Standard, Road Glide Special, Ultra Limited, Street Glide Special and Road King Special.
