School me if I am mind is a spounge...argueable a dry spounge
You are correct for a single stop in that situation but the higher hp bike would reach higher speeds (if the rider wanted to) on any given straight and so have to dissapate more energy over a certain time, say through a series of straights and bends.

If the two bikes were just cruising along at the same speed then their brakes could safely be the same.

But if you have the power you're probably going to want to use it!

Your 320mm rotor would probably be fine, my F650 has 300mm and weighs ~185kg (407 lbs) and that's more than enough.
