Since we didn't answer your question anyway, here is some more unsolicited advice. Find someone who knows bikes...a friend would be best, but I'm sure you can throw a little money at a mechanic to check it out. Get a used bike that has gotten the stamp of approval. Take a refresher course and PRACTICE. When you start feeling comfortable, that is when you should start to worry.
Make sure you factor good quality armored gear and a full face helmet into the equation. Trust me. It is expensive, but so is reconstructive surgery.
Man, I sound old. Just had a kid. Changes things a bit. Do what feels right, but be careful, and have fun, huh?
Remember, the bikes you have ridden are in a whole nother league. Starting out small (like a 250 rebel or ninja) is a good idea and you can get a used one cheap and sell it for about what you paid.
