Upon inspection this morning when the bike was cleaned after a first time 150km of public gravel road, I discovered that the smallish rear mudflap that gets bolted down by 3 hex bolts to the rear swing arm was loose. Upon closer inspection I saw that the top bolt was missing. I removed the two remainder bolts and discovered that the top bolt broke off inside the metal housing and it looks like if there was supposed to be a small stiffner bracket that also broke off as only a small piece of the bracket is still attached to the casing. Is this a known problem with the 1200 GSA's? It happened to a friend of mine as well when they went touring through Namibia and he lost his whole mudflap.
It has been known to happen Kobus.
I suggest you take it off and leave it off it is only there to pass German road safety specs!!
