James1_10018, I agree with what everyone else has been telling you. Please don't go for the Hayabusa right out of the gates. It doesn't matter how cautious you are or what the salesman says, things happen and if you aren't experienced that thing WILL get you. If you were going to start playing with snakes, would you start with a king cobra?
Xdfarrx, that's pretty much my thinking too. Something along the lines of the SV650 is the most powerful thing I'd consider for a first bike. The only reason I'd even consider a 600/650 is the fact that you don't grow out of them so much and there are a few very well-mannered ones out there that will let you make a few mistakes without making you suffer too much for it. In fact, many folks seem to quickly move up to liter bikes and then settle back down onto 600's and 750's.
V-Twin hiCross, it's just a personal taste thing for me - I've never been real drawn to other bikes like I am to the so-called crotch rockets. I'm not saying it's out of the question because that very well may change if I get to ride some different things at a MSF course or whatever. Comfort and safety is more important than image and for all I know, I may find out that the last thing I want is a sportbike - I just don't know yet.
Edit: Just saw your post Dallas... thanks for the info! And I would definitely wait until after the course, so maybe I'm sort of putting the cart before the horse here by getting into all of this now. I was just offered a nice CBR600F3 but it's just not time for that yet. And oh yeah, have fun testing which is better. :-) If I were you, I'd never reach a definite conclusion so I could continue testing indefinitely. LOL
