I own a Hero Honda Super Splendor.
I bought it in 2008 and have ridden 23, 500 KM. When I bought it, it used to give mileage of 60 to 65 KM for a liter. It now gives a mileage of 50-53 KM/Ltr. Is it normal for bikes like Hero Honda? I give it for servicing as soon as it time and the tyre pressures are as per recommendation. I am from Bangalore. Any help and recommendation would be great ?
