Making a Rumble

A former propeller factory on the outskirts of Milwaukee, Harley-Davidson Powertrain Operations on Capitol Drive was purchased in 1947 for the manufacture of various motorcycle components. Today the 450,000 square foot facility is dedicated to manufacturing Sportster® and Buell® powertrains.
In addition to the machining and assembly of engines and transmissions, the more than 600 employees produce Screamin' Eagle® Performance Parts and manufacture replacement parts for Harley-Davidson® motorcycles. Capitol Drive also houses the Harley-Davidson Engine Remanufacturing Program, where Harley-Davidson Evolution® and Twin Cam engines get a new lease on life.
Your tour experience begins as soon as you walk through the door. Designed to immerse you in Harley-Davidson heritage, the tour center features a Harley-Davidson engine timeline - from the classic "Flathead" to the contemporary Twin Cam 88®. You'll also have the chance to sit on the latest Harley-Davidson and Buell models and visit the gift shop which features tour-related merchandise.
The tour begins in the theater with a brief video on Motor Company history. Then it's on to the factory floor, where you'll watch Sportster and Buell powertrains take shape on the assembly line and see engines hot-tested to ensure they meet strict Harley-Davidson standards. You'll be guided through the Genuine Motor Parts and Screamin' Eagle® manufacturing processes and stop in the Engine Remanufacturing Department.
Powertrain Operations on Capitol Drive is the only Harley-Davidson facility in Wisconsin offering public tours. So make plans today to see the place where Harley-Davidson motorcycles get their rumble.
