It have to be new?? You probably won't find a NEW 600cc+ sportbike for under $6k after all is said and done. I'm sure there are plenty of 04 R[1|6], GSXR[100|60|75]0, ZX-[6|7|9]R, or CBR
bikes out there for sale. If not, wait until Feb or March.
It doesn't matter which one you get; they've ALL got looks and power. But, ALL of them have different geometries. So, go to a dealer and plant yourself down on a couple and find the one the fits... THEN worry about color. =]
My preference? Triumph Daytona or Duc Monster S4R (dark). I'll never give up on my SV though... =]
