Just a comment on the instructions that come with the top case. They are pretty basic and not descriptive enough (for me anyway) to easily install on the bike and the lock for the tumbler. Perhaps this is an individual issue but if you have more feedback related to this phenomena, best to let BMW know they need to improve their instructions on what to do (and not do).
Installed one side but the lower hole wouldn't line up quite enough. Lower hole offset about .5mm off. This contributed to the bolt not threading quite right and shaving some of the threads off mounting bracket. Going to drill hole a little larger to allow screw to grab what threads are left. Sierra is great shop. This bracket not the quality for the $$$.
