This Kawasaki rider will need a change of underwear
How did he get away with that?!
Having ridden the same bike below, I can tell you it's a modern Kawasaki ZX-10R Ninja. It'll do 189mph in fifth gear (and there are six gears) although the speedo stops reading after that.
In short, its 200 horsepower is very, very fast. So fast it turns relative straights into proper corners, as this extremely lucky rider found out whilst maxing out his ZX-10.
