Hero Honda Passion Pro is one of the best bikes under 100 CC. I bought this bike in 2013 January. Now I am using this bike for about 6 years. I ride my bike about 65000 kilometers till now. Two years after buying there was some sounds coming from the back break. I repaired it many times but after a period of time the sound comes back. Its the only problem I have faced with it. I am getting a millage of about more than 50 kilometers. Passion Pro is not so good for long rides, but its very useful for local rides.
