The heavier and rubberized factory bar ends do dampen vibration, but not noticeably. I don't notice the difference when I switch to the heavy Throttlemeister bar ends. Yes.... red loctite on those factory bolts. I don't use any when I'm switching. I suggest to use blue loctite if you really want to be sure. The bolts should come out without heat. Just make sure the bike is stable and be sure to use a properly fitting allen key or drive and be firm when you undo it. Don't be shy with it.
Look ahead, relax & GO HARD!
