I'm running SW-Motech ADV panniers on mine, the side-carriers arrive from Germany tomorrow, the cases themselves are a hold over from my Multistrada as they run over USD400 each. I coughed up for them on my Multi because I prefer top opening panniers so my stuff doesn't fall out. The side-carriers were USD325 for the XR, spendy. I do not use a top box, I loathe them, instead I replaced the stock "rack" with a Motech rack and run various combinations of Kriega gear on it.
