SS is my first bike. 4 Months (MAY 2012) back I bought this bike, so far I am very much happy with the overall performance. My bike returns the mileage of 55 to 60 km/l (using only shell normal petrol). Two times I have taken my bike for long distance (Bangalore to Chennai, nearly 400 km) without facing a single problem. I have reached a top speed of 100 km/h. The bike is easy to handle and comfortable to ride. I have not faced any vibrations even at 100 km/h. The bike is very cheap compare to other available in the market, I purchased at a price of 52000/- (drum brake and self start variant).
According to me there is no bike in 125 segment in the market giving a good mileage within a budget of 55 to 60 K (on road price).
