For one lack, you would be lucky to find a quality 250 cc bike in PK with the legitimite papers!
Yes i can only supply UK bikes.
Just to let you know, once i have the export certificate ready for a bike, i have to get a wooden box made to cover the bike. This wooden box on its own costs £200, lowest price and the shipping for this box is around inbetween £800-£1000 to PK via air cargo.
Customs and excise/taxation clearance is a night mare, even if i knew the officials there, it would still be a hassle and they speak as they are somewhere flying near the skyline.....
Are you serious that you have a budget of 1 lack rupees? and you are intended to purchase a 600 with papers?
