The Useless BMW Vario Top Box - the Revenge

BMW sell a vario top box made by Shad.  It incorporates a mechanism for changing its size but at maximum volume the box is not large enough to take a modern full face helmet as previously reported..  The mechanism is not well designed from a mechanical standpoint and jams easily.

I have therefore removed 1 kg of useless gubbins and bolted the box together in its maximum size configuration.

The vario mechanism - a real bind at the best of times.  The box has a sliding top hat incororating the lid assembly and a rubber seal

Over complicated and mechanically dubious in action - this little lot adds almost 1kg of weight and wastes space

With vario mechanism removed and the box bolted together more volume is available (although only  a little extra height is gained).  I could trim the screws I suppose.  The lid cords are attached to the rear most boss using ring crimps (not shown here).

I used dome headed 4mm stainless fasteners  - looks reasonably neat.
