Thank you very much for your answer.
Alps are not a problem, I can go along the coast.
In Madrid there are Embassy of Sudan and Consulate of Ethiopia but the visas are very slow.
OK, you're right, too much kms and little time but there is not another solution, only more work and more time to ride the bike.
In 2008 travel from Madrid to Cape Town in 50 days with a Honda XR 600 very very slow, was hard but really enjoyed.
OK, tnank you for all.
