This is more about the wow factor than anything else. So don't fret over the fact that you can't take a corner without dragging the motor, or that the belt on the left side of the bike is likely to rip your pant leg off, or that if it doesn't start in the first few tries you will likely have a dead battery. None of that matters because when this bike is parked next to others, they will all be invisible.
This bike was put together by Frank Ohle in Germany and is powered by a 150hp Rotec Radial R3600 airplane engine. This bike is amazingly unique and has to be one of the only 9-cylinder bikes around. Video of the airplane engine motorcycle in action after the break.
