India is connected by land with Laos and Thailand, so understandably many overland-travellers would like to do it by road.
But with Burma being practically closed for foreign vehicles, China very, very complicated and expensive to go to (nevermind crossing such a large portion of the whole country!) and the highest mountain chain on the planet, as well as the Tibetan high plateau lying between India and China, very few actually do it.
If you mean transporting your bike by train or truck, I fail to see the point. Would probably be much easier to freight it onwards from India, then spend a few weeks backpacking through the areas that are complicated to go to with the bike, then go meet it at the other end.
