i want to know about mileage given by indian bikes in 1 ltr of petrol in 125cc segment.i.e.how many kilometer do motorcycles run in1 ltr of petrol(manufactured by indian manufacturers as bajaj auto,hero honda,tvs motors etc)

In my opinion if you want complete&detailed information abt motorcycles, you can look in the market for auto magazines which are published especially for the purpose!From time to time, auto magazines keep doing tests and comparisons with various models available in the country.Go check it out!!!
