I still have the ZXR750R that I bought in 1991.
Sounds like a good AHRMA bike to me. As a 71 w/ race frame, it would slot right in to the Formula 750 class. Besides, there's nothing like taking your vintage bike - or modern triumph twin for that matter - out on a track day and chasing down moderns...change of pace from the norm.Still own a 750 Honda that I race back in 1976. <snip> It would probably only be good for track days, but don't have much interest in that with a bike that old. I've got a modern 500 and 600 for that anyway.
