I had Activa since 2015 and from then I didn't suffer any major problem. The engine is perfectly working and the battery is working fine also.
Horn and the indicators are in the good condition as well.
Accessory protection is also very supportive and very powerful. Even if your scooty becomes unbalanced and you end up falling on a road, there are more chances that you scooty will be fine with minor scratches ( only if the accident is minor) .
It is the father of every other scootys in the competition because the mileage is awesome. I used to load 100 rupees petrol in it and it lasts around 3-4 days and can cover over 50km non-stop.
This scooty is a trusted one go for it.
