KC, Just how itsy bitsy are you? My Cathy is about 5'4" and she used to ride my big Harley. She can't ride the BMW because her legs are too short. (I have talked to her about that...) You should be able to get both feet on the ground. Wear boots. Sometimes a thick sole on the boot will help. (you don't want your feet to slip either.)
Most motorcycle schools provide the motorcycle. You would be expected to provide: Boots, Gloves, helmet, and wear jeans and a jacket. Something that could take a bit of wear. There are riding suits that you can get that have built in armor. They have heavy teflon strips installed inside the garmet. So if you fall off at any speed, the armor protects your elbows, spine, butt, etc. I plan on getting that, when I get my 'eletric riding suit. Untill then I wear heavy jeans, and a $99 leather "bomber" jacket. Not the best, but far better than skin.
Let us know what you find. Take saturday and cruise your local motorcycle shops. Don't let them give you any crap about "oh, your too little, lets try you on this Honda 175". If they tell you that, well just jump up on a chair, and kick them in the knee. (just kidding.)
