I managed to explore this option at NEC last year I put photos of it and everyone said it was ugly
My wife likes the security of a top box but I don't like using them so I tried the GS Vario box and it fits perfectly.
It's fugly but it saves the cost of the SXR topbox option.
The number plate probably cost more than the topbox would have, by the time you flogged the vario!
Plate cost me £12 off the net........they will make them how you want, cheap compared to the DVLA prices
You know what I meant!
