handlebar crown[confused]
if putting an R top tripple on is what you mean, then yes, it can and has been done. there's crossraod style clipons from americansportbike.com which are easier, but you might be able to get away cheaper with the R top tripple mod.
i think it looks pretty damned good, and was gonna do it to my 9 but i got an 1125 recently, so i'll leave it as it is for a while
