Based off the Timeless design of the Ironhead Sportster, in 1986, Harley-Davidson upgraded the Sportster with the newly designed Evo engine, replacing its predecessor that had become a staple of the Sportster since its inception. Harley's decision to stick with the semi-unit construction of previous Sportsters resulted in a distinct valve train. Unlike most of today's motorcycle engines, the Sportster Evo uses just one cam per each overhead valve, resulting in four independent gear driven camshafts. This setup results in cam lobes that are in-line with each other, resulting in a parallel pushrod configuration.
