The French being French will just ignore any law they don't like and if the authorities start clamping down , they'll take to the streets and bring the country to a standstill as they've done before.
Unlike most countries , when French bikers protest , they do it properly .............
The FFMC (our equivalent to MAG) are are quite a powerful group who have been known to bring every major city in France to a standstill at the same time. Got caught up in one in Marseille once - very impressive.
The chances of being pulled in France by the police are slim if you're on British plates unless you're doing something really stupid. They can't be arsed with the paperwork.

I see there is no mention of the damage to the left hand (as you sit on the bike) rear panel below the seat, as for the other damage to the engine it appears to me be a substantial knock to have bent the stator in the way it has, therefore I would walk away as there is no knowing what other damage to engine components have occurred.
