As per my experience Bajaj discover 100 CC is most fuel efficient bike with great styling in India. It has a mileage around 70 KMPL and you can increase the speed upto 85 KMPH. Great handling and very good short pickup makes this bike very good. The Bike contain drum brakes which also very good. Lights are also very stylish in it. The Seats are comfortable for long ride. There is some gear problem occurs after 1-2 year where you will get a false gear problem but it can be rectified. Overall it is a good bike on prospect of mileage. Who have to ride more in the day for work, the surely can choose this bike as their companion on road.
