Screamin’ Eagle

Screamin’ Eagle crate motor launched for Touring models

HARLEY-Davidson’s Genuine Motor Parts and Accessories range has been expanded with the introduction of a new Screamin’ Eagle crate motor. The latest offering is the SE120ST, which has been developed as a bolt-in installation in H-D Touring frames with no required fabrication or engine mount relocation necessary.

To get the 120ci capacity the motor has a 4.060in bore combined with 4-5/8in stroke SE Pro stroker flywheel and rod assembly in factory machined engine cases. The Screamin’ Eagle inner crankcase gets a full complement cam needle bearings with a high-performance crankcase output bearing and nitride bearing race. The forged pistons fitted to the engine are 10.5:1 high-compression, nickel-plated and with Teflon coated skirt and they are fitted with Titanium SST piston rings. Screamin’ Eagle SE-259E high-lift cams are matched to high-performance lifters and Perfect Fit push rods. The MVA heads are CNC ported and fitted with automatic compression release.

The intake on the motor is a Screamin’ Eagle 58mm throttle body, which at 18 percent larger than stock is said to allow the engine to produce 106hp and 117 lb-ft of torque at the rear wheel.
Harley-Davidson is making the SE120ST crate motor available to fit 49-state 2015-later Touring models, and certification is pending for California 2015-later Touring models and all 50 states ’10-‘14 Touring models. The SE120ST is not compatible with Twin-Cooled models.
