Hi, I bought the new plugs for my 1150GS - Brisk DOR14LGS off ebay. Was a bit wondering when l got them. They look exactly as in the picture above. The gap between central electrode and side ones is somewhat big. Strange, but the bike started after I installed them. Made a test ride - bike was running normal. Now I wonder what mileage can I expect on those plugs? I was using NGK Iridium plugs before. After 20,000 kilometers they seemed to require a change, because bike did not start "on a half turn" anymore. Anyone who has used this kind of plugs, please share your experience. G.
