Looking for a fuel-efficient commuter motorcycle

I want to buy a fuel-efficient bike for my ride to work. I ride around 100km every day and currently use a TVS Star City Plus.

AAA If you want to stay within the TVS family, the Victor is the 110cc  commuter that we would suggest. This bike offers a great mix of style, quality, performance and comfort. However, considering that you have a long distance to cover every day, we’d suggest you scale up to a 125cc bike for a little more performance. In this segment, you could take a look at the likes of the Bajaj Discover 125, Hero Glamour or the Honda Shine SP.
