In 2019 I bought and fitted a SW Motech street rack which fits the Triumph grab rail. This week I thought the top box looked a bit loose and found that the left hand screw had snapped off and consequently the right hand side had broken plus one pulled one of the threads out of the grab rail. Has anyone else had this problem or is it a one off? I now need to decide whether to buy another rack or look to buy a complete pannier and rack kit. I have the Triumph panniers so I can sell these on. Anyone?
