From what I understand the law for the kits was scheduled for July last year but the 'period of grace' was extended to November due to supply problems, and I filched the triangle from my van when I sold it cos I had some auto-route riding to do, dont think its obligatory for two wheels.
I bought the bike from a 'depôt vente' ie private sale but the bike was in the shop.
After losing the bolts I returned to the dealer with my tale of woe and Michel the guv sourced 4 bolts for me fitted two (loctited) and put the other2 in my hand with a wry grin (Gratis but more to the point, not his responsibility) we stayed good buddies until he closed down last year, like a good few businesses round here.
