Just for clarity:
1) The Australian VIN plate riveted to the frame (and its number) are made up by the aussie govt and don't necessarily mean anything in terms of the bike model.
2) The frame number is stamped on the headstock and looks like it is the MC18-1012815?? maybe?
3) The engine number is stamped on the right rear of the engine, on a crankcase, and will read MC16E-xxxx

Are you sure the MC18-1012815 number is stamped on the engine crankcase?
If it is, it seems dodgy.
