Scrambler Rear Carrier Advice.

I'm getting a Scrambler 1200XE delivered next week. I'd like to use the bike for an occasional short weekend away, I have a fully loaded Tracer 9GT for serious touring. The bike has a rear rack fitted, and my question is what are my options for a small topbox. Will the standard Givi or Shad mounting plate fit on this rack ?

 

Thanks, I've looked at that, I don't want to add the SR6416 rear rack plus E251 Monokey plate. I was trying to find out if the generic plate provided with the smaller Givi or Shad topboxes would fit onto the rack already fitted to the bike.

 

That's what I was trying to find out. Generally on forums somebody else has always done something similar. I was quite fancying the Shad SH40 Cargo.
