If I were you, I'd seriously consider NOT getting a CBR, GSXR, R6, or 636(kawasaki).
If it's your very first bike, start smaller, and go up from there. The new 600's are ridiculously fast, and it's not just the power...sensitive brakes, handling, just not forgiving bikes at all. You're going to make a bunch of mistakes when learning to ride, and you're better off making those mistakes on something easier to ride.
Ninja 250 or 500.
Or if you have to go with a 600, the Suzuki SV650 or SV650S(fairings). And Kawasaki has a new Ninja 650 that's designed with a newer rider in mind.
Also make sure you take the MSF course!
