It wasn't long before most adopted the 70 profile front and 180 width rear for both, my understanding was that they tried to sell the 748 as a more nimble bike (presumably to compensate for less power?) and fitting a lower profile front and narrower rear made it tip into a corner quicker but it soon became apparent that it ran out of front tyre/grip sooner due to the lower profile. The narrower rear, however was a good thing.

I can confirm that the 748's, certainly the R's, are faster .. much faster.. into corners than 916's. Fitting the fatter rear profile trashes the handling. The power difference isn't that significant a good 916 has at best 9bhp at the limiter over my R. They're a much closer match than you'd imagine and that edge into corners and the insane corner speed they'll carry is a great leveler. The fast spin up of the 748 motor virtually compensates for the torque difference.
I like the 916's and the 748's, take the stickers off and you'd not know which was which without a close look.
