Some advice needed .... I'm intending to swap the crappy round mirrors on my '06 GS to the ones used on the F800/GSLC, plenty of comments on here about how much better the new style mirrors are. But do I need to look for the new type mirror from any particular model? The mirrors on the LC appear often to have plain base ends rather than threaded, some of the F800 versions are threaded but it's not entirely clear. I've not removed a mirror from mine yet to investigate the size of the thread or what the mount setup is, but it doesn't seem quite as straightforward as I initially thought, that is unless I'm missing something obvious!
