You could get some carbon plates to stick to the frame rails I suppose, which might stop them getting gravel rash.
In the three crashes I had on track the only things that took a bashing were the tank, tail unit / hand guard and widest parts of the fairing, bar ends and pipes - the bits you'd expect. Everything else is pretty well tucked out the way.
With stand bobbins on the swingarm that's protected, and if your lock stops are in the right place your bar ends will protect most other things.
