I wonder about the physical size issue.
According to the specs, the 750 seat height averages about 31.9 inches. The 500/550 is 31.7 inches. I can't find handlebar reach listed anywhere, but I can't feel much difference between the 750 and the 500. (The difference in wheelbase is maybe three inches.) The 750 is definitely a bit wider, but I don't see how that matters when the subject is bike fit. And of course it's a lot heavier, and I DEFINITELY don't see how that's an improvement. It's why I switched, in point of fact.
So I'm probably missing something, but at the moment I don't understand the POV that the 750 is the only SOHC that's physically big enough for larger folks.
As for displacement, well, okay. I see the attraction of horsepower, although I'm resisting it more easily these days. (I played with the real horsepower of modern bikes for a few years, and finally realized that I kept most of them out of the power band most of the time. 150 horsepower just isn't real useful in most real world conditions, IMO.)
But at the same time, SOHCs just don't make much power. Any of them. I mean, a properly tuned 750 is making what, 65 BHP? High twelves in the quarter? And topping out at 125? Marginal at best, at least compared to a modern 600. (Or 400, for that matter.)
I guess what I'm trying to say is that if we were into power, we wouldn't be playing with SOHCs. I like the CB750 an awful lot, but I feel a bit silly talking about "big bike horsepower" when parked next to a Haybusa, or repeating "No replacement for displacement" when the R6 next to me can utterly dismantle my 750 in every concievable situation.
So someone enlighten me. Did you really ride the 750 and the 500, 550, or 650 back-to-back and realize that the 750 was the only bike powerful enough and physically large enough to suit your needs? Or is there maybe a touch of perception trumping reality here?
