You are correct to be concerned about Aprilia's aftersales service as it is generally on the more expensive side, and the experience can also be hit / miss. Sticking with offerings from other brands like TVS, Yamaha and Suzuki would be our recommendation for a hassle-free ownership experience. 

Among your shortlisted options, the Jupiter, Ray ZR and Access are typical family scooters which will be comfortable, fuel-efficient and reliable in the long run. Our pick would be the Jupiter because it is the most rounded product, although the Access comes very close and is also noticeably quicker. 

Between the two sporty scooters, the TVS Ntorq makes for a better all-rounder because even though it is sporty, it doesn't sacrifice practicality or comfort. 

Take a test ride of all options you consider before making your purchase. 

The lightest petrol-powered scooters in India are the Yamaha Fascino and Yamaha RayZR, both coming in just under the 100-kilo mark. 

Other models you can consider are the TVS Scooty Zest 110 and Honda Dio 110, both of which are just a few kilos heavier than the Yamahas. Don't purely consider the specifications on paper. We would strongly recommend you go to a showroom and at least sit on the scooters to see which one is manageable for your petite physique. 

The most fuel-efficient scooters in the 125cc space in our tests have been the Yamaha RayZR and Fascino models. Both are mechanically and feature-wise exactly the same, with only different bodywork and styling separating the two. Some other proven and reliable options to consider are the Suzuki Access, Honda Activa and TVS Jupiter models - these are also practical, fuel-efficient, reliable and comfortable scooters with widespread service networks.

Scooters you can consider are the TVS Jupiter 110, Suzuki Access 125, and Honda Activa models. All of these are lightweight and manageable. 

If you want something even more approachable, then the TVS Scooty Zest 110 or the Yamaha RayZR / Fascino can be considered.

 A test ride will help you decide which one suits you best.
