I round a "BMW R1100GS R1100R R1100RT R1200 ~Black Leather Hat Cap" on eBay (Item number: 230047271375). So I asked the seller a question: "Will this leather cap work with an R850R? My roommate rides a K75: will this cap work with that? It's not an R, but it is a BMW. (I suppose that it's not at all Honda-compatible, though.)" I notice that for Honda Magna Shadow Spirit Aero ACE 750 1100 riders he has one face mask, and for riders of Suzuki GSXR Hayabusa GSX Katana RM GS SV he has a different face mask ... but illustrated with the same picture. I think people who make ads like like that on eBay are turds. eBay calls it keyword spam.
