Anyone Know anything about...

[Kyle]

Sport Bikes?...
I'm moving out next year, so i'm gonna need a bike to get around(cheap and don't guzzle gas)
Well, i need to learn how to ride a bike first...I have no idea how a manual works on a bike(someone please tell me)
and i just need to get the feel of riding first...so i'll need fast, but not to fast bike at first...
Anyone know good companys to buy from?...
I'll probably start with a bike from ebay first, then move on to a new bike once i get the feel of everything. And how many cc's should a beginner look for?

keep in mind that i know nothing of bikes yet, so if i need to know something...PLEASE let me know.
