Hello. There was a need to bring a frame for a motorcycle. This detail https://freebears.com/flanders-handlebars is a license plate, it needs to be cleared, and so on. Maybe someone has encountered such a problem and will tell you what you need - what docks the seller should have, how to customs, etc. I plan to buy either in the USA or in Germany. I was engaged in a similar case a year ago. The procedure is tedious but simple. I do not know, as in the Russian Federation, but in Ukraine at least.
