the panniers/side bags on my 2010 1200s did it, and now the panniers/side bags on my 2018 1260s are doing it. by "it" i mean when the bags are locked in position on the bike, you can move them about 3mm by pulling/pushing on the rear of the bag, pulling away from the bike. is there a method to tighten them up, os they do not wiggle?
Had the same problem after my friend knocked my bike over with panniers on. After checking three other 1260s with panniers at my local dealer all had play but not as bad as mine. Finally cured the problem by replacing the Hook and Fork on the pannier. Parts 4 and 5.....
