BMW V8 Powered Motorcycle by Harald Geiling
01 May Custom

Harald Geiling runs the Roadrunner Bikeshop over in Mainz, Germany, selling motorcycles and also doing a lot of frame repair. Somehow or another, the idea of building a V8 motorcycle entered Harald’s mind and being more of a doer than a dreamer, that’s what he did.

He bought a 4 liter V8 from a BMW 740i, and squeezing time in over a period of four years, he made the motorcycle pictured here. The engine is stock and produces 286 hp and 300 foot pounds of torque. The exhaust is an 8 into 1 running through a Kawasaki muffler. The radiator comes from a Volvo 340. He built a two speed gearbox which powers the belt drive. Wheels and suspension are modified pieces from various Kawasaki's.
