Its about the sound and performance what people love in this including me too, and yaa the two stroke engine which gives the crisping sound and for the name yamaha we get the performance. And the mileage may get around 35-40kmpl only for most of the two strokes, but incase if we convert to cat silencer and maintain the speed in 40-50kmph adn offcourse with good engine, the mileage can be boosted upto 55kmpl. its actually those who have been in this bike will only know how awesome its to ride in it, it cant be described in simple words, YAMAHA is always yamaha.
