The best activa model is its 3rd Activa HET but after this activa 3g came and after then now in 2017 activa 4g came both the new models is not so good in comparison to Activa HET but as all activa’s mileage is good and it is reliable also but not comfortable in long journey we got back pain and shoulders pain also comfort wise it’s not good and road grip is also not good when we drive and accelerate it cannot grip properly the road and sometimes it fly and slipped away but the Activa 4G looks awesome and stylish and aslo acceleration, power or performance is great and engine is also impressive.
