This one is the 4th generation of activa.
In terms of style nothing is new except front and side panel and new color scheme.
Revolutionary new feature is AHO and has BS4 engine which give 45 kmpl which is not that bad. The engine is smooth but on highway its does struggles with pace. Riding is also feels exciting thanks to pickup. Suspension quality is as required for our Indian roads.
There is much space on footstep and seat.
The cons are there is no telescopic suspension and seat storage is not that great as not a full size helmet fits in it.
Last word for Activa 4G is its trouble free, reliable and comes with amazing resell value.
