The Alu Rack adapter is designed to bolt to the Alu Rack thus allowing the Givi top case to attach to the adapter. The Alu Rack is a universal item AFAIK and it is up to the owner how to attach to the bike.The rear frame on the NT has two "hard points" (threaded inserts) already and two more that can be added. None of those seem to correspond with the 3 holes in that Givi top case adapter.
