Fitted the R&G extender to bike a little while ago (not overly impressed with the fit but ok - used supplied double sided tape and plastic rivets) but recently noted that it was a bit loose so took fender off to investigate. appears that the centre rivet and some of the extender had worn through from tyre contact. So i attached with some small stainless steel screws and locknuts. Next trip out leaned over to see fender swaying and wobbling in a worrying fashion. It appears that the fender is NOT rigid / strong enough for the extender so i have now removed it. i contacted R&G to inform them of this (not requesting any recompense or refund) but they did not even bother to respond. Not the first time that their customer comms has been poor. would advise an alternative is sought - seen the Wunderlich Black engine housing protection and wondered if this was any good??
