Looks like an amazing adventure, I'm very jealous. How long do you think it will take? Do you have the funds to ride for 3-4years? I guess that's how long a world trip would take without stopping.

I can't really comment on America or Africa as I haven't been there (yet) but here is my two bobs worth to get the ball rolling.

Europe: Is it worth spending some time in Scandinavia. Norway has some amazing coast roads, arguably the best in the world.
It doesn't look like you plan to visit much of Italy, but the Dolomites are well worth a few days.

Indian Subcontinent: It looks like Bangladesh is on your route, I'm not sure how it is to get into Bangladesh with a bike... I would check this out, failing that Nepal is a must visit.
The leg through Northern Pakistan, along the KKH will probably be the most expensive part to get through China. I understand from fellow riders that the few days will cost you US$1500 per person. This will take a chunk out of our kitty.

Australasia: I'm not certain but I think East Timor and Papua New Guinea are no go zones. Also, since you're going to Australia, you might as well see more of it than just the east coast. Go inland, see the real Australia. And if you go south, don't miss Tasmania, absolutely the highlight of Australia by motorcycle.

Also all up I see about 10 passages requiring either air or sea freight. I think that this will really start to hurt the hip pocket. If possible you might want to consider trying to reduce the number of times you freight the bike. If you estimate the cost of the bike and you to fly 10 times then at US$1000 each time it adds up to a lot of s, or tanks of fuel (gas).

Let us know how your plan progresses.
