Need help in selecting a bike interms Power and Mileage...

Hello everybody I'm having an idea to buy a bike which satisfies both mileage and power( normally 125CC).. I have enquired and selected some bike which contains both mileage and power....

1. Hero Honda Glamour
2. Honda Shine
3. Bajaj XCD
4. Bajaj Discover
5. TVS Flame
6. Honda Stunner

If anybody feel that any other bikes are better than the above six, then kindly mention....

I suggest honda stunner...

hmm.. TVS flame and Honda Stunner are the two best among them.
More or less, all above have mileage near each other.
But now I days I recommend Honda Stunner !

How much mileage can stunner gives...???
