Why would I want to toil a motorcycle to Asia?

[Voodoochile]

Hi,
I am new to this forum and new to motorcycles as well but I have spent enough time on the road as a regular backpacker to call myself an intrepid traveler. As I have acquired a liking for mountaineering, which requires quite some equipment to haul around, I thought it a good idea to plan my next journey on a motorcycle. That would give me an opportunity to carry some gear.
But how good an idea is it really?
My plan is to spend around two years in Asia, not only in the mountains, but all over the continent but as I brows this bulletin board I see a wall of obstacles piling up. Insurances, visas, licenses, countries off limits for bikes, impossible boarder crossings, etc.

I am still on a general planning stage and don’t need the details yet but my question is: Can you really spend two years on a bike in Asia without drowning in paperwork and bureaucracy? Or rather, is it worth it?
Are there areas that will not accept you with your bike (China?), only accept you for a too short time (Russia?). Can you get through the “-Stans”? Can visas and other paperwork be arranged at the borders or does everything have to be pre-planned (which is virtually impossible on a longer trip)?
I’m not the one who get put off by hardship or stubborn border officers but I start to wonder if I should leave the bike (and the climbing gear) at home. Any constructive answer is highly appreciated.
