VERY LOW MILEAGE (UNEXPECTED). Review on Mahindra Centuro

I purchased Mahindra Centuro in October 2014 because I was very excited to check its features like anti theft alarm, flip key etc. I was advised by many to purchase other bike but I didn't listen to anyone . I purchased this bike because it claimed to give 84 km per liter and I thought if it is saying 84 it must give at least 60 km per liter mileage. But all my expectations went in vain regarding its mileage.

Once a time I was doing job of collection of due amount of Airtel postpaid connection where I was getting salary as 10000. I was using my bike to collect money and I thought that expense of petrol should be below three thousand only but it came around 6000rs and I was able to save only 4000 from job. Ultimately I had to leave the job because of this bike. After using 2 years I thought to sell it in second hand market in Geeta colony in Delhi but no body was ready to offer me more than 15000 although it ran out y 11000 km. So I had to use it for self. Service Center of Mahindra Centuro are also very poor. They charge too highly and always find out new problems so every time bill is overcharged unnecessarily. I also found problems in its sound. It sounds unnecessarily. Mileage that I am getting from it is around 35 km to 40 km from very beginning till now although I get the bike serviced every 3 months and I use less than 1000 km every month. I hate its mileage. I will advise not to buy this bike if any one want good mileage.q
