Dont waste money in Chinese heavy bikes or chopper. They failed miserably in Pakistani market due to lack of spare parts and after sales and service. Although there are some good maintained chinese bikes on OLX. But again it will be a dead end.
if you are vintage bike lover than search for CB200 or 250cc bike
Invest in Ravi Piaggio 125 or Deluxe 125 or wait for sometime as there are some rumors of 150cc bikes.
