Had the BD up to about 125-130, front gets a little squirrelly, lots of head shake... I don't mind cruising along at 90-105 but much more is just not what these bikes are designed for.
I have had several sport bikes and have had all of them in the 160+ range on the "open roads..." I had a highly modified Ducati up to 181 on the front straight at MMP. But these bikes are built for it. The are designed with minimal rake, steering dampeners/stabilizers, low travel suspension, etc.... Now days....even at only 29, I try to keep anything over 90, be it car or cycle, to the track!
