This fully assembled Harley-Davidson Engine named the SE 120R (120 stands for cubic inch and letter R for Race)) is designed only for off-road and racing use.
It is made available to Harley dealers for their racing customers wishing to compete on the racetrack with an affordable high-performance race engine. .The beauty of this SE120R engine is that it is designed to bolt-in directly to a customer’s transmission and chassis with no special fabrication required. It is comprised of a wide variety of Screamin’ Eagle and other components, all manufactured in the USA.
Engine produces 135+ horsepower, 6,000 rpm, 137 ft. lbs. of torque and 3,800 rpm at the rear wheel. These results were achieved on a 2009 Dyna using the SE 58mm Throttle Body, SE Heavy Breather, tuning with the SE Super Tuner, and Wegner’s Stainless Steel Stepped X-Pipe for an exhaust system. The system was kept in open loop, meaning Harley did not use the O2 sensors. The Harley SE 120T engine has a limited production run each year and is currently offered only in Twin Cam™ Alpha and Beta configurations. Fits ’06 and later Dyna models, and ’07 and later Softail and Touring models. At your Harley-Davidson Official Dealer.
