I bought CT100 couple of months back. So far I have very good experience with my bike. It gives decent mileage of 75kms in worst traffic conditions in Bangalore.
I would definitely say it is a great value for money considering the high mileage & the price at which this bike comes. Power is also fine when compared to other bikes in this category like Centra, Dawn........
Looks, also better when compared with Boxer & other bikes in the same class. It has added features which were not existing in Boxer. Well, you get all these added features at a astonishingly lesser price than boxer. Thanks to Bajaj for that. Sincerely, if you are looking for a bike in mileage segment, CT100 is the best bet.
However, having said that I am concerned over the road grip. It is not the best in class when it comes to road grip. I was about to fall from the bike for couple of times due to bad road grip. I am riding bikes since 3 years.
I am also little concerned over the resale value of bajaj bikes. It is not as good as Hero Honda. That may be for the reason that Bajaj keeps coming with new bikes every now & then and they stop production of older bikes.
