The first real street bike i had was a Honda VTR 250. Just about the equivalent of that, except Honda, not Kawasaki. I got sick of it after a short time and moved to a Yamaha FZR600, then CBR600F2 and the list goes on and on. I know they say to learn on something small, but if i had it to do over, i would have started out with a 600 to save me from the hassle of selling and getting another so soon. I also had dirt bikes throughout my childhood also.
