by the looks of it (online parts finder) it fits a whole range of bikes from 85 2T upto great white 1290 Super Adventure.
54201081000 is the old part nr from 2004 (no 2007 Duke II?), its replaced by 54201081100 same model range.

I also did a search of the part number but could only find this 54201081000 as the parts list only shows Adventure and gives me no option to pick 640 Duke 馃拋

the LC4 frames are pretty much the same construction-wise from 1994 onwards. only real differences are there is or isn't an oil filter in the front downtube, space to remove the oil filter from the engine past the frame (bottom right side) and oil breather/filling plug on front downtube and some mounting points.

the part nr you provided is correct, however it has been superseded by the new part nr 54201081100.
so yes it should fit
