Morning Doc,
I have a Givi top screen off a 2016 Versys 1000. The rails are 175mm apart at the widest point on the parallel run.
You can have it for free if you want it ( it was destined for the bin anyway

), PM me with your name and address if you are interested and will post it out next week after I "source"

some bubble wrap from work. I also have the mounting clips if you need them ( not sure how universal they are though

), let me know.
