I think this is the biggest and the most disappointing part of this bike. The engine capacity has now come down from the previous 153cc to 149cc. Not just that, the power has come down from 13.80BHP to 12.92BHP and the torque has come down from 13.6Nm to 12.8Nm .Apart from this the engine is still an air -cooled, 4-stoke , 50Hc, 2-value unit. But be aware of the fact that the motor is not fuel injected
