Honda makes a set of saddlebag scuff pads which are supposed to go on the lower part of the bags by the passengers heel.
They stick on with the same stuff the rest of the Honda tank pads etc use, I believe it is a 3M two sided tape.
You can install them on the top corners of the painted section like I did on my last 04.,they fit perfectly. After that you can put a strip of 3M Clear protective film about 6" wide and long enough to cover the rest of the top curved area you normally scuff with your boot.
You can't see it (the 3M film ) but it's there. That's what I did. Here's a picture.
