Buy the Suzuki SV650S!!!
I have owned mine for about a 2 years and I'm still finding changes I can make to it. The aftermarket parts for this bike are crazy there are so many. This was my first bike too. I bought it for 6,500 out the door and I'm very happy I went with the SVS. It's a blast to ride, flickable, light, powerful and I have heard it can beat an in-line 4 in the twisties anyday. (I havn't had the chance yet-that's just what I heard). Anyway go to SVRIDER.COM and look around I think you'll be pleased. PEACE! Get back if you want more info.
