106-HP/117 lb. ft. Performance Potential; Bolt-In Installation; Street Legal
Harley-Davidson’s Screamin’ Eagle SE120ST Crate Motor (P/N 19221-15, $5,695.00) is possibly the ultimate in factory-engineered street performance. The 120-cubic-inch engine is designed for bolt-in installation in an Original Equipment-style Harley-Davidson Touring chassis with no required fabrication or engine mount relocation. Equipped with a Screamin’ Eagle 58mm Throttle Body that’s 18 percent larger than stock, this engine is capable of producing 106 horsepower and 117 lb-ft of torque at the rear wheel. The crankcase, cylinders and heads are painted black and feature machined aluminum highlights and chrome covers.
For best performance results, Harley-Davidson recommends combining this engine with a Screamin’ Eagle 58mm High-Flow Air Cleaner (P/N 29400222, $159.95) and a Screamin’ Eagle High Flow Exhaust System (P/N 64800022, $1,299.95).
