Both the TVS Jupiter 110 and the Suzuki Access 125 are good options to consider. The Jupiter is a more modern scooter and offers far more features than anything in its class. Also, it's very practical thanks to its huge 33-litre underseat storage area. The Access has all the strengths of a traditional family scooter, but it has peppy performance that will put a smile on your face during daily errands. 

You can also take a look at the Honda Activa 125 since you are familiar with the Honda ownership experience. The bigger Activa is a smooth, comfortable, practical and fuel-efficient scooter which will also be reliable and easy to live with. 

We suggest you take a test ride of all three scooters to see which one you find more comfortable.

The TVS Ntorq 150 is the most powerful scooter in your shortlist, and it will also be the most fun to ride. It is also the most feature-packed, with a TFT display, Bluetooth connectivity, riding modes and a host of other features. The TVS Jupiter 125 is a more practical option, with plush ride quality and a huge 33-litre underseat storage space. 

The Suzuki Access 125 is a family scooter with peppy performance that should be very reliable and fuel-efficient, too. The Honda Activa 125 doesn't have any one standout feature, but is a proven package you can't really go wrong with.

Take a test ride of all four so you can pick the one that best suits your needs.

Since you have had such a nice experience with your Honda Activa, you can look at the latest Activa 110cc and Activa 125cc variants of the scooter, which will carry forward the same sort of experience your current scooter delivers, with added features. 

If you want to look elsewhere, the TVS Jupiter models and the Suzuki Access are our current favourites in the scooter class. If you would like something that's flashier in terms of looks and has slightly more performance without sacrificing practicality and comfort, the TVS Ntorq is a good option. 

Considering you have some back pain, we would recommend you stick with a motorcycle as the big wheels, longer-travel suspension and neutral riding ergonomics will keep you shielded from road imperfections. Inside your budget, we would recommend 125cc bikes like the Honda Shine 125, Hero Super Splendor / Glamour models, TVS Raider 125 and Hero Xtreme 125R. Depending on the sort of style you are after, you can choose between any of these. 

Since you have asked us about a scooter, our current top picks are the TVS Jupiter 110, Suzuki Access and Honda Activa 125. While the scooters will be more practical, they will not be as ultra comfortable as a motorcycle over bigger bumps. 

Take an exhaustive test ride before you decide. 

From a comfort point of view, the Bajaj Chetak models or TVS iQube range will serve your purpose well from the sea of electric scooters available.

In the 125cc space, the most comfortable options are the TVS Jupiter 125, Honda Activa 125 and the latest Suzuki Access. Even the TVS Ntorq 125 is a good option if you want a sporty offering with peppy performance.
