Hi Alan
The DVLA is a nightmare of bureaucracy whatever size bike,car, etc you have!. However I have an awful feeling that the French "Crit Air zone information" will raise bureaucracy and chaos to a whole new level. To travel through France now it would SEEM that you needto check EACH DAY on your Smartphone or I Pad ( neither of which I posses) whether you can enter this or that zone whether you have or have not got the right Vignette etc as access to the various zones will depend on a number of variables, which can change daily. I quote one phrase in all the guff "Old vehicles of all kinds cannot obtain the Vignette and have no permission to drive during the day......." The series of dots are theirs, so goodness knows what is next. Do any of our French members understand all the implications of this and have they had problems planning a route. This looks as though it is going to be a real problem particularly for the foreigner who only travels a couple of weeks a year, and of course will be impossible for someone without a Smarphone, I Pad etc. M-rde!
