Actually, with all due respect, but you are missing the point here, The parts for the HD bikes sold in India will still be made in the good-olde USA, but will be shipped to India in large crates, so that HD can claim "final assembly" in India in order to avoid the ridiculous import duties. They are not going make any parts there (other than maybe screws and fasteners), and the are not going to ship parts back to the US.
As I said earlier, car manufacturers such as VW/Skoda, Mercedes and others do exactly the same thing.
On an related note, how well they will be able to compete with Royal Enfields (which still makes ancient British bikes in Tamil Nadu that look similar to HDs) remains to be seen. I would guess that HD and Royal Enfield will have very different price points for their bikes...
