This may sound like a stupid question. I have the Harley four point docking hardware installed on my 13 FLTRX. I just got a detachable luggage rack. My question is, Can you have a detachable luggage rack and a detachable passenger backrest attached together at the same time? The reason I ask is that I also just got the two bag luggage set. The larger bag has a pouch designed to slip over a backrest or sissybar, for extra stability. I can tie it down using the attached D rings, but I was curious about the detachable backrest. Any insight would be appreciated. Also anyone have any recommendations for a rider backrest?
