I think you're correct, cleanrider.
I just don't see how a change as significant as a 23" or 26" front wheel, can't not have an effect on how a bike handles, and I just can't imagine the change as being for the better. Pretty sure there are very sound mathematical reasons why you don't see big wheels at the track. The big wheel conversions are usually accompanied by conversion to a single front brake disc as well. Given that a larger diameter wheel effectively lengthens the theoretical lever that exists between the contact patch and the axle, I don't think having even less braking power is a step forward. I suppose going to a larger diameter rotor, and a 6 piston caliper could level the playing field. Then, there's decreased clearance between the fender and fairing, especially if the forks have lowering kits.
All that said, they look cool as hell, and if that's what a rider is looking for, go for it! But if one does go big, I think restoring functional rake/trail dimensions, is a wise, albeit very expensive move.
As they say, opinions are like a$$holes, everyone has one, and they all stink. Mine is no different! Ride what turns you on, and have fun. It's great to live in a land that allows us to do such things!
