1936–1947 Knucklehead Engine
Precisely Recreated in 1/6 Scale
Where vintage V-twins began — the timeless engine with the knuckle-shaped rocker covers
Introduced in 1936, the Knucklehead was Harley-Davidson's first production OHV V-twin. Named for rocker boxes that look like clenched knuckles, it laid the foundation for chopper culture and for the great lineage that continued with the Panhead and Shovelhead.
