Just to update anyone who is interested, have received my COC from that very nice man at Honda Europe.
The Nox reading is 0.14 g/kw happy days so all is not lost for us with the older bikes, just for reference my VTR is an F2 registered March 2003
Only have to register the bike with those nice people at TFL.
So much for the Gov & TFL drawing a line at 2007 and staying bike was not compliant 
just par for the course. Don't despair give it a go.
