Shipping my motorcycle to London was a piece of cake. I brought it to the cargo division of Air Canada, disconnected the battery, loaded my gear, put it on a scale and then I payed 900 CAN $ to fly the bike to London. In less than 30 minutes all work was finished.
Tomorrow afternoon I can collect the bike at Heathrow.
And I finally found out the exact weight of the motorcycle. It turned out to be 320 kg with an empty tank.
Adding 30 kg of fuel makes it a round 350 kg I have been dragging around the world. Better said, it dragged me around the world.
