Purchased 2 x new carbon 7 series helmets from BMW in Port Elizabeth in September 2018. Used once in December and then once in Feb. for short trips. Went on a long trip in April and my sun visor/dark visor would not go up or down, first time I had used it. Took it to a dealer in Bloemfontein who said the cable joint had broken and it was a replacement warranty. Rode back to Port Elizabeth, took it back to dealer. Dealer submitted claim to BMW H/Office, then to Germany. Mmm, a claim, yes, but no stock. Only new stock available in October. Really poor service. Why no stock Internationally? Maybe a major problem with all system 7 helmets? Anyone else have similar problem?
