So I am on Hayabusa #2 now, due to an unfortunate theft incident. I can tell you with certainty that the silver/blue is much faster than my new black/blue...it is because the black absorbs more light, making the bike heavier. Or maybe it's because I am still in the break in period. The black does show little scratches better than the silver did, so I need a tank protector. I don't think I want a tank bra, but something removable would be nice. What are you all using? Any recommendations? Thanks!
