leaving or giving a bike in north america
 

hello
i would like to know if there is a legal way to drop a french bike i would like to do send back to europe after coming from south america with it (K75 with french registration)
giving it for spares could be a solution, but i don't know if custom officers do write her in the passeport
last solution is to go back to Mexico
cheers

Just import it - bikes are duty free, you can do it at any Port of Entry (you don't need to cross a border).
