I have been using this bike for the last 2 months and I am totally impressed with its performance.
I have already ridden the Pulsar, Suzuki gs150R and Unicorn and therefore, I can compare the NVH levels of this bike with others. Its 125 cc engine is brilliantly smooth, efficient and revv happy.
To get good mileage one has just keep a track of the real time mileage indicator, which helps in improving our driving habits. So that a mileage in the range of 65-70 kmpl can be obtained even in city conditions and 70+ kmpl on highways.
