This bike is a 150cc bike but the exhaust sound changes after about 10000kms on it.Also the sound changes after long rides. The build quality is not so good.Most of the body parts gets loosen up moreoften.This is not a value for money bike either.You spend most of your money on maintaenance.The brakes on this bikes are not so effective.The discbrake gets locked up on hard brakings that can lead to a crash. The mileage is not bad for a 150cc bike but there are few things that needs to be improved on this bike.
