Description
The Evolution engine riding in the nimble Sportster frame is a prime example of the power, durability and proven reliability The Motor Company was built on. Born from the legendary Shovelhead and Ironhead engines, its been the power at the center of a Sportster motorcycle since 1984. Its overhead valve design and four-cam gear train have their roots in the companys race program, and you know it when you feel the surge of brute torque that accompanies every twist of the throttle. The air-cooled V-Twin design with a compact one-piece crankcase/transmission fits the narrow Sportster profile like a fist in a fingerless glove. We began with a strong, trouble-free design. Then gave it constant refinement to bring us to the modern powerplant of today. A testament to the unwavering hunger for advancement in motor technology that has always driven Harley-Davidson.
