I ride an 06 Ninja 650 myself. You will be doing yourself a disservice if you get anything below a 250. Honestly, a Ninja 650 is a GREAT beginner bike. It's relatively light and it won't murder you if you over do the throttle accidentally.

However, if you think a Ninja 650 is too big, look at the 300 models. Yamaha R3 or Ninja 300 are great beginner bikes. I believe this year, Kawasaki is also releasing a Ninja 400 (although as a first time rider, I would not recommend buying a new bike. Buy a beater you can learn on, because it will take a few scuffs, I'm sure)

Your best bet is to go get your permit and take the MSF courses. they will teach you the theories of riding as well as give you ample practice time on little Suzuki gz250's.

And after you're done your MSF class, you get your license.

I was in PA when I got my M license and the MSF courses are free in PA. Not sure if they cost anything where you live. Definitely look into it though.
