pannier

Hi, i'm looking for pannier racks for my Tracer to mount these : Expedition Dry Saddle Bags by Wolfman Motorcycle Luggage | Wolfman Luggage and came across the Givi PL2122CAM Tubular Cam Side Pannier Holders, has any one got these racks, if so the dimensions of the actual loop would be useful...

Just finished my last job on the bike with the panniers being fitted, photo attached. Mods completed: Carrier rack, Tail light re-positioned, Top box, Seat, Ding knobs, Rear stand knobs and stand, Light screen, Roo whistles, Pannier rack, Heated grips, Pannier quick disconnects and Pannier...

I went out on my Tracer yesterday and when I stopped my right hand pannier was missing (Yamaha panniers, dealer fitted). I had checked that the panniers were secure before starting out so can only assume there was a problem with the locking mechanism. Has anyone else had this problem?
