Those are Goldwing passenger floorboards. Goldwing as GL1800 full bore wing. They are all over eBay. I got a used set for about $75 and refurb' them and repainted.
I have a roll of clear and black skateboard tape I was going to install for that very reason. Great minds sir.
I did repaint the floorboards. The black I used was a very close metallic match to the 2015 Super Fast Matte Silver models blackish frame parts. From side angles it does compliment very well to the frame color. If you would like, I can shoot a pic of the rattle can color I used.
