No gearbox, no exhaust system and no lights sure makes for a pared-down motorbike. At least it's got an engine, however. And a nice little stand that stops it falling over when you're sitting on it in the office.
Student Edwin Yi Yuan is behind this air-brained invention, and he and his tutor at RMIT in Melbourne, are hoping to set a world land speed record in South Australia - once they get the stabiliser thingy off, I assume. It's basically a stripped-down Suzuki body, with a rotary air engine fed by high-pressure air tanks. As we all know, I'm not exactly good on the science bit of stuff, but what would happen if you're wearing heels and you puncture the tank (as you do when you're one of those fantasy chicks with big la-las, a leather bikini and tramp shoes?) I'm almost tempted to nominate myself as a test driver to find out. I'll have to do something about my current wardrobe, however. [Motorcycle USA via Core77]
