I have yamha szr 2011.Today I am sgaring my experience about this bike.This bike comes with 150 cc engine and its give a damn good performance.This bike has very low resale value.This bike disc break in front for your better safety.You can sit really comfertably in this bike.This bike is good in 150 cc class it gives.There are some problems also, this bike don’t have any passing light swich.One problem that I faced first is fuel metre get damaged very fast.Some times getting missing while riding this bike.We have to change the air filter every time.Comparitively the front tire of this bike have more life than rear.
