Hi all, Anyone ever used this company before, think they`re based up in Cumbria somewhere. If so, how do you rate their slip ons (all hand made apparently). I have a 08 RSVR and just wondering whether I need to get the Map changed if I just go with a straight swop from standard to aftermarket end can ? Apologies if I`m being a bit dim but its the first RSV I`ve owned (picked her up yesterday - will post picks when I get a sec) Cheers, Paul
