In Europe , especially in Germany ,the distribution is "state of the art"
In general ,... EVERY tyre dealer is able to order E-10 from the "big 5" in Germany.
( if a dealer won´t believe in the that ... show him this side from one of distributors
They also are able to provide you the approvals ( for bikes registered in Germany ) as a print out...
