Yes this is another chrome VS polish question!! I have seen in several post that the chrome will put more weight on the bike. Well that is obvious. Say if you got your wheels done, really how much weight is that going to add? Is there a standard like so many square inches weighs this much? And would it really effect every day to day performance? I'm not talking on the track or nothing just pulling a few wheelies and hitting the back roads?
Only way it would really make a difference is if you are a serious track racer where as every second counts. But if it's just about everyday racing on the interstate, if your racing skillz are polished, you shouldn't see a difference at all!!!
