1929–1948 Side-Valve Engine
Precisely Replicated in 1/6 Scale
The side-valve engine, affectionately known as the flathead, supported the dawn of vintage V-Twin motorcycles.
Introduced in 1929, the side-valve engine is characterized by its flathead structure with valves located next to the cylinders. As the mainstream design before the advent of OHV, it was widely used for both military and civilian purposes, with displacements ranging from 45ci to 74ci.
