Righto
Don't need breathalyzer(s)
Don't need a bulb kit
Don't need a triangle
Don't need to have hi viz vest at all as it's about reflective area on gear not a bib, most bike gear already has strips on them which more than covers what you need.
It is greed that bikers cannot carry all that crap and is for cars and larger to have.... not for bikes
There is a law stating you should have reflective strips on helmet although I have never heard of anyone being pulled to check a sticker on helmet (been in France 5 times now in 12 months alone). Again unless you are riding at night no one is gonna check.
Must Haves.....
Need original Docs (not just photocopies)
take 2 sets of keys (good point by Andy)
make sure you Insured for bike in EU
make sure you have EU breakdown
Carry Passport and docs with you at all times
EHIC card to cover you for medical needs.
I had an accident in France on my Rocket 3, 4 weeks ago and had to use pretty much everything listed above.
Anything anyone not sure about Pm me as don't want to take over Andy's thread. If you have never been to France it's a fantastic place just watch out for their car driver
