BMW very helpful AS USUAL !!
New box is indeed strengthened underneath:
But... I just do not know if it can be trusted.
I am unhappy losing the ability to remove the box easily... I tend to place all of my valuable stuff in the topbox, particularly camera equipment and I do not wish to lose it !
So purchased the Topcase Enduro Lock for £15.20 inc VAT :
Removed mounting plate and all of the plate rubbers, inserted necessary bushes.. and bingo.. box secured.
It can be unsecured with an allen key, but without care, the bushes would be lost unless the securing bolts are immediately replaced. Therefore not a fantastic solution... but now secure.
Has anybody with a new type box suffered cracking or box falling off, because if not, then the mounting kit may be unnecessary?
