Brace is not needed but did improve high speed and low speed handling on mine.I have had the Superbrace on for many miles and believe "For Me" it is a big improvement.Before the brace I had no wobble or have heard it was a problem.As far as some not liking talk about brace's,oil ect remember some here are just getting there F6B and like feedback for there concerns.I think winter is getting under the skin to some of those Northern boys!
