If u r looking for a bike that gives decent mileage, unique look, and other pros - SS125 is the best choice.
Coming to the cons:
Spares are very costly, and some times it takes more than a month for delivery. And I personally faced a problem with the carburetor. with full throttle, bike ll suffer with the flow in speed and it ll start to cough.
Really that was a bad experience if we are going for a long drive. The only solution I got from the mechanic is to change the carburetor that too within the period of 20 kms (2 years).
So decide while choosing your bike.
Better to go with traditional way of selecting bikes ie., going for best seller.
