My name is Ayaz Khan. I bought Apache 200 4V (no. U.P 20 AX 6067) Bike from your TVs ms siddhi motars bairaj road bijnor 246701 (U. P) showroom on 2/11/2016. When I bend the bike slightly to the left, then there is a very dirty voice from the bike engine. I complained to the TVS service center and TVS showroom but those people did not help me.In the last three months, I complained about my bike in the service center, but the behavior of those people was very messy. I also complained to T.M. Rishabh Gupta, but he did not do anything.
