Thats not a route, its a starting point and destination. There are many routes you can take, especially through Central Asia. Turkey and Iran have good roads, Pakistan and India have all sorts of roads, good and bad. Covering the distance in India is slow and painful, often only 150-250kms per day is enough.
We airfreighted from Chennai to Bangkok by Malaysia Airlines, cost around 600 euros. But we had a Vstrom, so if you can make a smaller crate for an XR400, might be cheaper. That was via Kuala Lumpur, so I would think it shouldnt cost much more to go there.
