By the way what i have heard about bike duties is that they are charged at per cc, not sure what the current structure is, that other guy in this thread may have helped many others by providing some info here in the open but i guess for his help you need to spend some $
Sending a 1000cc bike to Pakistan is not a good idea in my opinion, the duties are so high that people just leave their bikes at the port and afterwards when they get old, govt auctions them
better sell your bike for 10k, bring that money here and buy yourself a 5k worth 600cc of 2005 model.
