well if its a gixxer then all the bike are pretty much the same 600/750/1k body size so when ya get exp you most definately wanna get into either busa or 1k or 750. You really will not be able to use bike to its potential so why shift so dang much and get a 1k or busa and just stick in one gear and ride. ONCE YA GET enough experience and your the only person that will know
6'3 225lbs, I started out on an 02 600. Yeah, I'm slightly cramped, but then again it's a sport bike not a lazyboy. I know that starting to ride on a sportbike is not the best idea, but I know enough that the throttle works both ways. I can't really say any sportbike fits me well, but I imagine some adjustable clip ons and rear sets will make a big differance this year. And yes, I still get a huge rush on it when I snap it open, even with my fat ass on it!
