Mark van der Kwaak’s BMW R90/6 bobber

You don’t see many of these around. It’s a vintage BMW motorbike given the classic bobber treatment by Mark van der Kwaak of DBBP-Design in the Netherlands with help from his friend Aad Heemskerk.

The engine is from a 1976 BMW R90/S with Stromberg carbs feeding through custom-made manifolds. The frame is mostly new with some oval tapered pieces rescued from a 1951 BMW. And yes the front end looks more familiar: it’s a 45″ H-D Springer. Other parts were sourced from swap meets or built by Crime Scene Choppers using CAD plans created by Mark. [Thanks to Phil Davis.]
