The cam followers used in Sportster engines, K models, big twin side-valve models, and the side-valve W model series, were a slightly shorter version of the followers used in the larger motors, but featured the same 0.731-inch (18.6 mm) diameter body and 0.855-inch (21.7 mm) diameter roller follower used since 1929.
