Archived Petition: Seek to end taxation on transporting privately owned motorcycles to/from the EU
The Government must make an agreement with the EU to allow third parties to transport motorcycles, used for tourism, to and from the EU duty & tax free and agree with the EU that only a letter of authority from the motorcycle owners will be needed to transport motorcycles through the EU border.
