I am owning a passion pro 2013 model from the starting it gives 55km/liter now 2016 it gives 41km/liter.the shocking thing of the bike is it is a 100cc engine even a 160cc engine bike also gives a better mileage from this.The proof for this complaint is I filled petrol for 100rs it gives only 65km/liter previously for 100rs it gives 92 km/liter very worst experience from this bike even honda bikes are very good compare to this hero bikes.its time to sell this soon.
