I am using hero bikes for 6 years. But when I bought achiever my head turns down. At first It runs very smooth and no other sound comes from it. But after a year(good maintainance) sound quality deviates. If you say about Fuel Consumption first year is around 50-55 kmpl but after a year it goes down to 40-42 kmpl.It is its main fault. It is very comfortable and easy to handle and control.Back look is not good but front is vey good. It would be better if it comes with a digital speedometre.
