I own a Hero Honda Extreme Bike since 1year 3 months. From first service onwards I repeatedly complain to the service person regarding my bike poor mileage,poor performance and annoying engine sound. During intial stages of bike servicing, service person say that during intial stages bike wont give much mileage once 3rd servicing is completed, bike will be giving its best mileage. But now all my free services got completed recenlty, even then mileage didnt improved. Worst part is mileage got even worse. My bike provide me 35-40KMPL as mileage before, but now it provides 32-36KMPL.
