I bought tvs star city bike in year 2006, this was my preferred bike as it was the lowest priced and featured pack bike at that time. It was good to be its owner for me in early days but as the time passed it showed to me its true colour.Biggest disadvantage of it was that it has very few authorised service stations and its spare parts very costly than other brands also they are not always available easily in the market, once I had to wait for new silencer for 20 days. I have to got its engine repaired 6-7 times in this period which was very heavy on my pocket. the money I saved while buying it was too little in comparison of the expenditures on it in after years. mileage was like any 100cc segment bike, pickup was ok .
Plus points are silent engine, comfortable ride in city.
Negative points are costly spares, less service stations, frequent engine failures, heavy body with low bhp.
