Once I get the girl broke in I am going to do a comparison on the two bikes. I want to be fair, My 07 had full Akarpovic, pcIII, K&N FILTER, air box mod, Butter flys removed,cool air injection blocked off, +1 rear sprocket, renthal street fighter bars, Corbin seat.good breaded brake line,ect. the 2010 is totally stock.So far the 07 wins but I haven't broke it in yet. I did a 70 mile loop a round Charlotte last night and the 10 dose vib more than the 07 at 5,000 rpm but I read thats because the 07 had full exhaust, which makes it smoother. more up dates later.don't comment unless you have rode both bikes! or else thats just a opinion. An opinions are like A-holes and we all have one. You KNEW THIS WAS COMING RIGHT?
