Axiom Cycles sells Harley Davidson & Custom Motorcycles parts and accessories at competitive prices.

Harley Davidson manufactured the flathead engine between 1929 and 1974.   Flatheads did not have overhead valves.   Instead, the valves ran alongside the engine and opened upwards into a chamber beside the combustion chamber.   The advantage of a flathead was simplicity -- no push-rods or rocker arms, and the head was a simple casting with a hole in it for the sparkplug.   A typical Flathead engine had a displacement of 45 cubic inches (742 cc) and produced about 22 horsepower.

The Flathead was similar in valve operation to the venerable flathead engines that powered now-vintage American automobiles.   Harley's Flathead, with its constant-loss oiling system, remained in production until the mid-'70s, when it was used to power the familiar three-wheeled police trikes.

The Flathead was named because of the telltale flat vented tops that are recognizable at the top of each cylinder head.   This is the famous motor that propelled Harley-Davidson to victory after victory in the motorcycle races of the twenties.
