I was purchased Hero duet in October 2016. so now my hero duet is 6 month old. I had done two services of my scooter in service centre. and I am going to third service of a scooter in Hero service centre. but I am not Street Fights satisfied with mileage of the scooter when I was purchasing Hero duet. company claimed its mileage 63 kilometre per litre. but my hero duet is giving only 35 kilometre per litre mileage . this is very ridiculous and very bad. comfort speed pick up etc all things are good of Hero duet. but I am not satisfied with mileage of the scooter.
