Nomme bhai windshields are not that expensiver if we import our self, it will hardly cost you around 45$ including every cost and will have every thing in the box to fit it on any bike from 100cc to 150c local market.
let me know if you wana buy faizaddawood007 knows my home and you can pick it from there.
Also there is one used WindScreen of Dr.Omair avaialble also (he switched to different design wind shield later on) if you are interested then you can get that cheap as well..
on the other hand locally made (qinqi) rickshaw screens are also avaiable in market but they dont have that quality also they are very huge for Bike... and if you ask them for carving a special one for you it costs toooo DAMN much becuase they have to make a custom makings for it.
