Honda Aviator is the sibling of the honda activa.I would say that it is more improved version of the honda activa but with less riding comfort.It is stylish and good looking with good boot space and come in two variant.One with a disc brakes.I found it uncomfortable for ladies cause I found it bulkier than honda activa and it is having even more height than activa maybe due to large tyre size.But I would suggest you to pick honda activa than aviator If you are a girl and if you have one then try aviator.One plus point that I found in aviator is its pick-up.
