I just installed a GIVI monokey case and M3 plate to my gs500. All went well except that I cannot understand how a little 2mm plastic cylinder is meant to be an 'anti theft device' I suppose it may stop a child under the age of 3 from stealing my top case, but surely even a 5 year old can work this one out. On the rear of the M3 mount is the latch hole, it's a triangular piece of metal that that is attached with two allen head bolts secured from underneath. WTF? They supply a little piece of plastic that is mean to go into the Allen head hole. It may defeat the praying mantis that is lurking suspiciously close to the latch, but I can't see how it's going to stop a casual thief with an allen key from removing my expensive topcase. The obvious thing to do was to have the bolts coming from the top so they are covered when the case is attached. I'm mystified as to how it could be like this surely others must have noticed this. Should I take it to a welder perhaps? I mean I can't see why I'd even need to remove the latch, it could even have been made in one piece instead of needing to be attached. Unless of course there is something bleeding obvious that I am not seeing.
