The panhead is an ohv Harley-Davidson motorcycle engine, so nicknamed because the rocker covers resembled cooking pans. The engine is a two-cylinder, two-valve-per-cylinder, pushrod V-twin, made in both 61 c.i. (EL) and 74 c.i. (FL, FLH) displacements. The Panhead engine replaced the Knucklehead engine in 1948 and was manufactured until 1965 when it was replaced by the Shovelhead.
As Harley-Davidson engines evolved , the distinctive shape of the rocker covers led Harley enthusiasts to recognise an engine simply by identifying the head, with names such as "Flathead", "Panhead", "Knucklehead" and "Shovelhead".
Currently,[when?] a number of third-party engine manufacturers produce custom panhead-style engines in a variety of bores, many much larger than the original-design displacements. Each manufacturer includes upgrades to the original design to improve the performance and reliability while still providing the original styling and overall engine structure.
