As you would expect, a traditional Harley-Davidson big twin resides in the Springer's engine bay. In this case, however, it's bolted tightly into the frame, not floated on the vibration-quelling mounting system found on the cheaper Dyna Low Rider, among others. The Springer Softail is for riders who want the V-twin experience undiluted. Courtesy of a narrow 45-degree V-angle and a single-pin crankshaft, they definitely get it. Just like the Dyna, the Springer has a five-speed transmission and tidy belt final drive.
