Honda offers nearly same features on both the Activa 3G and the 125. The basic difference comes in the engine size and availability of disc brake. If you prefer higher speeds and secure braking, you can opt for the Activa 125 but the recommendation would be for the Activa 3G. The engine is a highly reliable motor, giving a good mileage and the combi braking system works pretty good on the 3G version.
