I disagree, the logic is flawed, but this wouldn't lengthen the stopping distance at all... a bigger rear brake (more stopping power @ rear wheel) would have done precisely dick. the reason IS weight distrobution, now if the CG of the bike were further back, and lower, then the rear brakes would have done more of the stopping, and the bike designers would have made the rear brakes more robust to compensate. but because the CG is so high, and so far forward, you must rely on your front brakes to do most of your stopping, and the rear only so crub off a little speed before it loses contact with the pavement.
