The Honda SP160 is based on the same platform as the popular Unicorn and should have similiar strengths like good comfort, exceptional fuel efficiency, as well as durability and reliability in the long run. 

The TVS Apache RTR 160 4V is one of the best options in the sporty commuter bike segment and will offer you good performance and features without sacrificing comfort and practicality. Do bear in mind that if you are a tall person, then this bike will feel a little cramped, especially with its tight seat-to-footpeg distance.

Coming to the TVS Ronin, this bike will offer you more performance and comfort than the other 150/160cc options you're looking at, but it will return lower fuel economy. And since you're looking at the base variant, you'll only get single-channel ABS like the smaller bikes. 

The Yamaha FZ-X Hybrid will likely be the most fuel-efficient machine of this lot, but it offers lacklustre performance, and its comfort levels aren't that high either.

Our advice would be to take a test ride of everything you shortlist before making a decision. 

Since you are a new rider and want good fuel efficiency, we'd recommend you stick to machines below 250cc. You have many good options in the 150/160cc commuter space, like the TVS Apache RTR 160 4V, Bajaj Pulsar N160, Yamaha FZ models and Honda Unicorn / SP160. These bikes will be light, manageable, fuel-efficient and also decently comfortable for a pillion. 

You can also take a look at sportier machines like the Yamaha XSR155 / MT-15 and KTM 160 Duke, although pillion comfort won't be a strong point on any of these bikes. 

If you want something that's a little more powerful - but still beginner-friendly - bikes like the Bajaj Pulsar N250, TVS Apache RTR 200 4V, Honda CB300F, and Suzuki Gixxer 250 models are options to consider. 

Do take a test ride of these machines to see which one suits you best.
