Ok guys, here is an update.
first, i thank all who have posted their openions and suggestions!
Today, i went to the Honda's and kinetic's showrooms and tested the Activa (Dio was not in stock), Nova, revamped KineticHonda,eterno and the blaze.
What I found out was, when i was astride the vehicles, the handlebars of evry one of them except the blaze was touching my knees and the worst is the kinetic nova. There was virtually zero handle bar movement when I put my legs in the normal driving position. Even on the blaze, there was still some obstruction but that was negligible compared to the others.
Also there was a 1 month waiting period for the Activa and a 2 month one (which could be reduced to 1 month on payment of additional 1.5k it seems) on the dio respectively. As i have to commute long distances and couldn't wait for that amount of time, ive placed a booking for the blaze (red with disc brakes).
I have one more question, what all does the "on the road" price include? I guess it will be ex showroom price+insurance+?
