It's all about content laws. American car manufacturers and Harley can get away with stating "made in America" due to content laws. They pay the politicians who approve legislation that determines what is made where by simple percentage factors. Europeans are no different. Every country caters to their base by patting them on the head and telling them that what they believe to be proudly made in their country is true. Very few companies can actually make that claim and when they do, they are very vocal about it.
