Most would think a radial airplane engine is best left for airplanes. Frank Ohle is not one of those people. This mad fabricator from Germany found himself in possession of a Rotec Radial R3600 airplane engine and decided the best place for it was not in the sky, but in fact on the ground, in a motorcycle.

Being the skilled handyman he his, Ohle fabricated a custom frame to fit the radial engine, painted it, added suspension, brakes and the rest of the details and built himself a completely functional chopper — powered by a nine-cylinder radial airplane engine! All in the span of 18 months.

Check out the video below, courtesy of our German friends at Motorrad Magazine, to see (and hear!) Ohle’s creation in action. It’s in German, but the bike sounds awesome no matter what language you speak.

    Now that’s something completely different from the ubiquitous cruiser fare and unlike Jesse James’s attempt this one actually runs.

    Ugh, I’d hate to do the carborator cleanout on that.

    It gives you that Fighter Pilot feeling. Looks like it’s fun to drive.
