We bought the Kinetic Nova DLX about 6 months back after a lot of contemplation between the Honda Activa & Kinetic Nova.
I think, I made a good choice. The Nova is a very powerful vehicle, especially its pick-up. The mileage is good if you are not into heavy traffic areas otherwise, its quite okey-dokey.
Initially, I had some problems due to bad settings done by my service center after my first service, but after it was fixed, now its good.
Currently, there are only 2 problems that I face - one is that, sometimes, it takes time to get started on cold or rainy mornings. And the other is the low flooring which brushes & scrapes with speed-breakers and small potholes.
But on the whole, I am very much satisfied with my decision & would surely recommend the Nova as a very good vehicle.
