I had a Kinetic ZX for about 5 years and then decided to dispose it off. Went for Honda Deo. Its a 110 CC, 4 Stroke engine bike.
I have been using it for the past 6 months and no problems so far (Touch Wood). It has a strong frame. I have rammed into a car and an auto rickshaw so far and have done away with just a few scratches. Gives a mileage of 45KM/L on an average.
Lots of space under the seat. It can hold a full faced helmet.
Drawback is its headlights. They are not on the handle and when I move the handle, the light falls elsewhere.
Since its a 4 stroke, takes some time to warm-up in the mornings and have to use the choke to restart after every 6 hours.
Less leg-room. Quite uncomfortable for the pillion rider to rest his/her feet.
Will not advice people with less than 5 feet height to go for this bike. The seat height is too high.
