I have purchased passion pro almost 15 months back. As per my experience its a very good bike. Mileage is very good. It gives me 65km/litre. I usually drive at the speed of 40-50Km/hr. Pick up is also good. Power is not good as nothing much about it can be expected since its a 100cc bike. Engine is smooth and design is very stylish.
In highways I go above 60Km/hr. Very smooth riding. I have not faced any issues till now with my bike
