When are you going?
I'm off to France, Germany picking up the Rhine and to the source in Switzerland. from the 4th June for 12 days.
Items required can be found on the www but here is a rough idea.
Medical ID card European Health Insurance Card + copy
Both sections of driving licence. Copy of for safety
Insurance details + copy of insurance and vehicle details
Honda Owners Card
Passport + copy of it.
In case you loose or get robbed a copy of the documents is handy.
Gear spare bulbs for headlight as all others are LED, plus fuses, possible pump and puncture kit.
Spare keys in safe location
First Aid Kit plus space blanket.
Hi Vis Jacket or band. We found the standard of driving and attitude to motorbikes to be good.
Camera for the views and memories.
If using the tunnel it's easy and they now contact you a few day before to check in (too allow you out now

Suggest GPS with European Maps and plan the routes ( I use Tyre to Travel ) http://www.tyretotravel.com/
and you can select avoid tolls and Highways (Mways)
Hope the list helps and enjoy the trip.
