O5 is fine for that just not 03. Is yours a red bike or black? Never seen a red bike with black frame that's all.
As for 749r back end he only talks of the subframe and tail unit
bought it mid summer last year for £3k its an "s" mono with red with black frame black swing arm, black wheels but old style fairings( with air slats) reg plate is 05. i heard that the factory is known for building some bikes out of what ever is lying around.
