Hello
I am a Finnish guy and I have been driving in the Nordic countries (Denmark, Sweden, Norvay and Finland) and in Europe, not a lot by motorcycle, but by car.
Welcome to Europe, if you are thinking to drive in Sweden I suggest you drive the Baltic round. You could drive from Holland through Germany to Denmark Frederikshavn and then by ship to Göteborg in Sweden and from there you drive to Stockholm, from Stockholm to Turku in Finland by ship, and from there by driving to Helsinki, and from Helsinki by ship to Tallinn in Estonia, and from Tallinn through the Baltic (Estonia, Latvia, Lithuania) to Poland, and back to the Central Europe.
Also, I with my friend would be intended to make European tour with bikes, substantially the same round but in addition to France and Switzerland, Poland, and the time would be same as the Le Mans race.
Greetings from I and my Spyder RT
