I own a Bajaj Platina 125cc and it is the best for fuel economy which gives 80 KMPL. The looks are not good but who cares? I fuel it for 200 rupees and travel for 200 kms. The maximum speed is 110 KMPH which doesnt give enough mileage. It gives upto 80 only when rode in the speed of 50 kmph.
Pretty reliable on everything. Single spark plug and 4 gear suspension with disc brakes.
