You can wrap the airbox and the underside of the seat. The vinyls available nowadays match most paint colors. We have done this on a couple of black bikes, as the underside and the rear of the airbox were getting chipped up. The airbox is the tricky part to wrap because of the odd curves, but the cut lines can be right at the edge without any visibility of the wrap itself.
Of course, you will need to pull both items from the bike, which isn't that difficult
