The date and the Place can be because of the weather really does not separate completely.
In the Alps (Albertville, Madesimo) it before July, and from September 12 get chilly for motorcyclists.
Monschau, in Brittany and the Vosges mountains in the Alps and I would not go because of the rain before June 15 to the motorcycle.
The weather I do not, I expect realistic possibilities.
All planned places I like. In Brittany, I've never been to the other places I've driven motorcycle with a lot of fun.
All locations are planned for me to reach by bike.
Schedule I almost always free.
