I have made some calculation. The fuel economy which I am getting is around 55-60kmpl.Also it will surely improve with time.
Pickup is amazing along with acceleration is more than good for rough use. But do not expect this to match the Aviator, as the aviator is much better.
The Dio is free from vibration untill the speed of 60-kmph. It can rum comfortably at the speed of 50-70 kmph.
Minor vibration will creep in if you above 70-kMph.
Speed untill 70kmph is quick, but after that the progress is not so good. Honda Dio bike is not idealy suited for the highway road.
Handling is amazing because of the low weight of dio. The seat is also long and comfortable.
