This bike sounds like having silencer at the exaust.the sound of the bike is good and the milage of the bike is also good.i have this bike for almost five years and this bike is good.it takes the speed of 50 to 60 km/h very fast and it have four gears and you can beat many bike of that range easily.i love this bike.the maximum speed that I have been is 100 km/h.and I dont think that it can be more the bike’s speed increase very slowly after 80 km/h.but it is good.the grip of tire is good but when you turn on the road and lean the bike too much then it feels very litlle scared that you will fall.but all the things like look of the bike is average.and it is comfortable also.
