Which is the top milage bike?

Bajaj Discover 100

Hi, Bajaj Discover 100 DTS-Si is the most fuel efficient bike currently available in India. The bike has 94.38 cc, Air-cooled, 4-stroke, single cylinder, DTS-Si engine with 7.7 hp @ 7500 rpm of power and has 7.85 Nm @ 5000 rpm of torque and gives mileage of around 75 to 85 kmpl depending upon the riding style and conditions. Bajaj Discover 100 DTS-Si bike has style and mileage but lacks engine reliability and has shorter life span and is not a consistent performance bike and has very less resale value.
So its better to go for the reliable Hero Honda CD Deluxe. The bike has reliable 97.2 cc, Air cooled, 4– stroke, single cylinder, OHC, Digital CDi engine with 7.8 hp @ 7500 rpm of decent power and has 8.04 Nm @ 4500 rpm of torque and gives mileage of around 70 to 75 kmpl mileage depending upon the riding style and conditions and has good resale value.
