Not quite clear on if you are planning to replace valve stems on all three bikes (1150GS; 1150RT; and a K1200LT) and want to know if they all take the same stem. If you do a search of previous threads regarding valve stems, I recall that some people have said that because the LT wheels have a ridge around the middle of the rim, some stems won't work. I'm not sure the other two models have the ridge. I run a straight short metal stem for tire pressure monitors on my LT and angled stem wouldn't work. :bmw:Can anyone recommend an angled valve stem? Will the same one work on 115gs 1150rtvand 1200lt .
