I will be selling some shortly as it happens, bought some Givi Panniers with quick release racks and can`t use them with grab handle as they bolt to original rack

shame really as grab handles really tidy the back up, to much hassle to be changing bits over to fit panniers so grab rail will be going, ( not for £50 tho, last one on E-Bay sold for £150

thats dearer than buying from BMW, think they are about £130ish complete with logo from dealer
