Thanks for the replies and picture which helps a lot.
It looks like they have replaced the tail light you have to be a 2nd stop light which really works well - however, this means that the bike no longer has a number plate light. This mystifies me on 2 counts - I am fairly sure that the the hard luggage rack system is Yamaha's own ( the hard luggage certainly is), the bike was MOT'd by the main dealer just before I collected it (she's just under 3 years old so it would be the first MOT).
I don't know but shouldn't this be part of the MOT check?
