Hello everyone. I hope to soon buy a bike. Not sure on what make but i do want something in the 600cc to start off with. I have riden a bike once before, but you can really say that i'm a first timer, a virgin. I have been looking around and it's a toss up between a Honda CBR600rr, F4I, or a Yamaha YZF-R6, YZF-600R. Just wondering if you guys can give me some input on what to look for.I'm Planning on buying a used bike like (99-01) since it will be my first bike. Any advice or opinions are welcomed.
