I've been riding for a little over a year right now and have done a majority of it on a ninja 250. I am currently borrowing a GSX-R 600 until I can find something that I can comfortably learn to stunt on. The GSX-R is too big for me (5'6, 5'7-5'8 with boots on). I'd also like something that I can take into the twisties and enjoy.

I am looking for recommendations as to what would be a good bike to learn to stunt on for someone my height. I've been told to look for a F4i, but those things are hard to come across where I am.
