What's this about a "120R" Last I knew the largest stock engine was the SE110 ?
It's not a "stock" motor but rather a "crate" motor.
From the 2011 SE Catalog:
A. Screamin’ Eagle® pro SE 120R High-
Performance Crate Motor
This track-ready 120 cubic inch Screamin’ Eagle® Crate Motor
is waiting to provide a racing enthusiast the opportunity to
go racing at an affordable price. This engine is designed for
bolt-in installation in the Original Equipment-style chassis
of your track bike. No special fabrication or engine-mount
relocation is required. The crankcase, cylinders and heads
are painted black, and feature machined aluminum highlights
and chrome covers for a stunning “show-and-go” look.
When equipped with appropriate high-flow throttle body
and injectors, an open air induction, and tuned exhaust, this
engine is capable of producing a reliable 135+ horsepower
at the rear wheel.
Hand assembled alongside Harley-Davidson’s production
Twin Cam engines at the Pilgrim Road Engine Plant in
Milwaukee, these race-use engines feature only the finest
Screamin’ Eagle components:
• 4.060" big-bore cylinders.
• 4-5/8" stroke premium forged flywheels.
• 10.5:1 high-compression nickel-plated forged pistons with
Teflon coated skirts.
