1929–1948 Side-Valve Engine
Precisely Recreated in 1/6 Scale
Known as the Flathead — the side-valve engine that powered American V-twins before and during the war
Introduced in 1929, the side-valve engine is defined by its flathead layout, with the valves placed beside the cylinders. As the mainstream design before OHV arrived, it was offered in 45ci to 74ci versions and served widely in both military and civilian use.
