This is a conceptual Red Bull motorcycle as designed by Barrend Massow Hemmes. While we are on the subject of motorcycles, what's up with those dudes riding bullet bikes without helmets? Seriously? You are riding a race car motor with handle bars, weaving in and out of traffic, all the while having nothing separating your squishy head from the pavement in case of a crash? Empty it may be, but it's still worth protecting. Ah well, natural selection in action I suppose.
