I'm not sure what to make of the Racer from RK Concepts. It looks fast, but maybe juuuust a bit over the top. Plus I'll bet that bikini babe walked away with a stab wound from sitting on it.
If you are into the design, you might be interested to know that it runs on a a Buell 1200, it has a 27-degree rake, 23-inch (58cm) tyres and the gas and oil tanks are fabricated out of glass - which, like a lot of things on this bike, doesn't seem safe. Still, I gotta give RK Concepts credit for pushing boundaries here. [RK Concepts via Cyril Huze via Born Rich via DVICE]
