I have my personal experience with it . initially my father told me not to buy bajaj bikes but I have not listen then and gone for it.
And today iam regretting . initially you will find good response and mileage too. But after 2 years. Its like garbage .mileage gone down. And engine response also. Now I cant move above 60 speed. Engine is soundinglike it will going to burst. Go for hero bikes or honda. Recommended.
