This is sweet.
Want to be a badass? The bar has been raised.
German motorcycle fanatic Frank Ohle spent 18 months outfitting his chopper with this nine-cylinder, Rotec Radial R3600 aircraft engine. (Model number courtesy of TopGear, I can't tell a Rotec from a Rotax.) Not only does it look like Ohle's sitting astride a jet engine, like some cartoon character, but it also makes a ton of noise, which seems to be one of the chief pleasures of riding a motorcycle.
The video is in German, but you get the idea. The propeller, by the way, is just for laughs. No word on the top speed.
