If I did stuff a set of 750 pistons in my S I wouldn't do it without getting some sort of FI programmer on the bike. I'm not worried about heat. These bikes run very lean from the factory, and a tuner will add more fuel, which will cool the burn down. At least that's how I see it. I also doubt Honda would go to the trouble of re-doing the cases just for an extra ~70cc. When the parts fiche for the new bikes come out I'll do some part number comparisons for the internal parts. If things like the rods & crank are the same I don't see why the bigger pistons wouldn't work. The only other parts I think that might need changing are the injectors, but I doubt it.
