PANHEAD HARLEY ENGINE
panhead 2

In the fall of 2007, S&S introduced an engine with a retro look, but with updated technology. The pan head engine has been hailed as the coolest looking classic engine of all time, and the Flathead Power™ P-Series engines from S&S captures that retro styling from the 50's and 60's with 21st century engineering. Keep in mind that as cool as these motors look, they are not reproductions. These engines were built to run!
