DITTO!!!
I noticed a huge difference when changing lanes on the freeway. Sometimes I would get that little "wiggle" from the cracks or lines in the road. Not anymore! This is a large bike that pushes a lot of air out of the way at high speeds and the brace noticeably keeps my bike stable. I was skeptical about them too because I never had one before, but after my experience on the F6B I bought a brace for my Sportster and I'm extremely happy with the results. Much more stable at all speeds and especially when changing lanes on the freeway/highway. I have the Superbrace on both bikes, and I think the first thing I will buy for all future bikes will be a Superbrace.
