Majority of bike owners have a family of minimum 4 persons, so - this classic straight modal serve thier purpose best as they all can fit on one bike, IMO the new modals all good for young generation and until they are single because after marriage they have to change traditional way of how women sit on back seat and i don't thing it will happen within this decade. So, if you think IF Indian bikes are allowed in Pakistan will replace these classic modal and will overtake market than you are mistaken because
1) They will not be cheap as they are in India because on general Pakistan has 20% custom duty and approx. 5% other clearing charges on imports and other business expense - So a bike which cost $800 in India will cost more than $1000 in Pakistan which will be too expensive as Honda/Yamaha is not the only competitors there are brands which are sold at $400-$500 price tag
2) They %age of middle class parents who will spend $1000 for bike of his son to send him to college/university is very less
3) One of the basic customer need here is the capacity along with goodies, So a customer can sacrifice goodies over his basic needs. I.e. A milkman and sales man will always buy a bike on which he can load almost a truck load stuff, a common man will always buy a bike on which his wife and kids can fit and is cheap to maintain
Yes Indian bikes will force local manufacturer to improve the quality and gadgets but classic design is not going anywhere in near future. IMO, Indian cars have better future in Pak market as compared to bikes.
