Did not purchase a brace yet. Haven't noticed the need for one, find the bike very stable at speed. Chased down a fast kid on a 750 cc crotch rocket yesterday on high speed romp on a very twisty road well known Westchester County road, on his tail the whole time and went around him on the outside at one point. But I'm a very experienced sport bike rider and ride the F6b the same way I ride my ZX12R. Very, very Impressed with the handling of the F6b, UNBELIEVEABLE is a better word for a bike as big and heavy as it is. Only thing lacking, for me anyway, is not enough power and not having a sixth gear. The kid was amazed that I was riding a Goldwing, his words not mine, LOL. Told him had I been on my 12R I would have been around him and gone three miles back LOL. Love the F6b yesterday was first time I really pushed it to the limit since I got it two weeks ago. Great bike, a true sport tourer ! Glad my wife wasn't on the back, she freaks if I go Over 60mph.
