Quick update. I now have my bike properly registered in France, number plate fixed, insured and now ready for a few french/Spanish kilometers. Homologation Honda France had the answer to my difficulties. They informed me that the computer database at St Gaudens Prefecture was not up to date and would be rectified. It was, and my next visit with all my paperwork proved fruitful. It only took 18 months and a lot of patience but finally its resolved. I am very happy to have my bike on the road. Thanks for everyone's help.
