Looks like they finally had the official announcement of the 131 M8 crate motor. Impressive specs on it! and bolts right in place on the 2018+ Softtail if it originally had the M8. i wonder who they were gunning for when they released this bad boy.
Harley-Davidson announces Screamin' Eagle Milwaukee-Eight 131 Crate engine for select softail motorcycles. This engine produces a claimed 135 ft-lb of torque and 124 horsepower at the rear wheel. MSRP is $6,195 for the oil-cooled engine and $6,395 for the Twin-Cooled engine.
