Its a piece of metal Honda have welded to the frame to get people talking to each other in total confusion. The only thing its ever done for me is get in the way when i've been messing around in that area. haha I would imagine it cant be a secure mounting point as any chain or security device would scuff the fairings in that area. Plus why fit one on the rear foot rest on the same side.

Its a hoisting point for when its in the factory so the rear frame can be moved around and painted without leaving any blank spots without paint. Its not welded on securely enough to be anything other.
