You're a brave man, and you will prevail. Some people have walked around the world, others have bicycled, and still others have taken little mopeds around like yours. So have no fear, but bring money, good money,lots of money, best US$$$. Try getting the most difficult visas first: Most difficult: China, exact itinerary is essential. Next: Russia, again exact dates of entry and exit are required. See a travel agent and the embassies of the two countries. Once you have arranged these two, you can work on the other visas. Get as many visas as you can before leaving home. On the road a visa may take as long as a month to come through. So start working. Read everything you can get hold of on the countries you are planning to visit.
