I just finished installing Doc Humphreys "Air Ryde Rock Guard" on my 2011 RTS. It wasn't a difficult installation if you are at least an average mechanic. You need to have basic hand tools and a couple of jacks. Three beers and a BLT also helps.
What is it and why do you need it? It is a rubber or neoprene cup that fits under the Air Bag for the purpose of preventing small rocks from working their way between the bottom of the bag and the swing arm. That area is completely open and it collects small stones that are thrown about by the rear tire. After awhile the stones will puncture the bottom of the bag and it will need to be replaced. The bag alone is about $250. Labor at a dealer will be at least two hours. So figure about $500 if you are lucky.
When I installed mine, I cleaned thoroughly between the bottom of the bag and the swing arm. There were several stones residing there.
Just letting you know this product is out there and it appears to be a good piece of prevention.
