is going from a 50cc to a 600c sport bike a good idea and which sport bike...

...would be best? ? i am only 17 and thinking on the lines of gsxr cbr and ninja's and i would have it restricted for the first couple of months to get use to power before making it full power (yes i know its a illegel but im willing to take a risk)
after everyone comment i am still getting a 600cc bike but am keeping in restricted until i am allowed to have it de-restricted so yes im not putting peoples lifes in danger also not making bike riders look bad
