Are you thinking of a 765? An old 955 is nice and comfy, I’m 6’2 and have no problem on mine but a 765 might be a bit small. Haven’t tried one though as yet
You might consider a Sprint as a compromise. I suffer from some.of.these problems common to aging.I found the Sprint capable, fast, yet still pretty comfortabe. But not quite a sport bike. ...J.D.
That’s why I didn’t keep my R6 that long. Being 6’2” it was certainly a bit cramped on any ride over about 30 miles
