I own a grey Tvs jupiter from the past 6 months and I have had a very good experience with it.
It is reliable and provides a lot of features. It is better than the activa on every criteria. The engine is smooth and mileage if above average. The looks are good and is suitable for both males and females.
Pros:
External fuel filling
Big 12 inch tyres.
Pass light swith
Patented E-Z center stand
Alloy wheels with tubeless tyres
Good cutioned seats
Front hooks for carrying luggage
It doesn't have any major cons. However, the look could be improved and made different.
The TVS servicing has been great so far. The on road price before GST was Rs. 65, 400 in Raipur.
Go fir it without thinking twice, its the best gearless scooter in india without a doubt.
