Switzerland to mongolia 2011 trip planning help needed

[Zimi]

Hello everyone. I'm planning a 6 month trip alone in 2011 with my 91 BMW R80GS Paris Dakar. I will leave Switzerland in march-april and come back in september-october.

My Idea is to go from Switzerland to Mongolia (yes I watched long way round and loved it) and if I have enough time, come back with another route or juste go on as far as I can and then come back by flight (maybe sell my bike or let it ship back).

I would love to have some suggestions from people that did similar travels. I don't know this part of the world. I traveled a lot in southeast asia and south america but I have no experience of eastern europe.

I have found those alternatives, don't know what is the best. I must say I would love to ride as less as possible on tarmac! ;-) and I hate highway.

here are my alternatives:
1)Leaving Switzerland crossing Austria, slovenia, croatia, romania, ukraine, russia, Kazakhstan and Mongolia.
2) instead of going through Romania and Ukraine, going through bulgaria and Turkey ad then Russia.
3) Instead of crossing Kasakhstan, going through russia up to mongolia.

Some more questions:
-How is Kazakhstan?
-can I get a multiple entry visa for Russia at the border or do I have to apply before?
- How long do you think I would need to arrive in Mongolia? I'm not really aware of how far can i go in 6 month. I plan a 200-300km a day maximum.
-if I have enough time, I could send my bike to finland from Russia or Mongolia, and then drive down until I got back to switzerland....

Anyway, you see it's not clear not, I'm quite interested in your opinion and experiences. Like what are the country that I shoulnd't miss on the road or the country to avoid. My goal is not to trough the most possible countries, but to have fun, meet nice people and see beautiful landscapes.

Thanks in advance for your help!
