what motorbike should i get?

ive ridden an aprilia scooter around for a couple of years. its a 150 but it has been worked and it goes pretty hard. i only want a bike to impress the chicks because the scooter is unbeatable in the job i do. only that when i have to take a girl out on a scooter, its f*ckin embarrassing...so i want something that will make them wet with excitement. i was thinking something like an R1 or Ninja?? Is that too powerful and am I going to be able to control it? or is there something else that will do the job? Im not looking to throw it around, just get laid...
