The holy grail among Harley-Davidson engines is undoubtedly the Knucklehead V2. Built between 1936 and 1947, this powerful ohc engine rolled off the production line in Milwaukee alongside the Flathead motor with its side valves and provided impressive performance in its day – on both the EL and FL models, the „Superbikes of the 1930s and 1940s".
Ehinger Kraftrad used an engine from 1940 for the Black Knucklehead and painted the drive unit – like the entire motorcycle – a rich, glossy black. "A Knucklehead engine like this is a genuine pre-war engine,“ explains Uwe Ehinger. "You have to step hard on the kickstarter a few times to get it to run. If you just want to press a button, you don't understand the philosophy behind these bikes."
This bike is also slim, but with its bulbous fuel tank and 16-inch rear wheel, it sits a little more firmly on the road than some other Ehinger creations. Everything else is typical Ehinger Kraftrad: minimalist, tidy and carefully designed down to the last detail.
