Reduced mechanical noise Kawasaki Ninja

Cam chain tensioner with an automatic adjuster, like that on the KX450F motocrosser, eliminates mechanical noise caused by a loose cam chain and reduces power-robbing friction loss

Silencing mechanical noise allows the use of a freer flowing exhaust for a better sound quality. Complex construction with reinforcing ribs helps eliminate airbox reverberation and reduce intake noise. Air filter accessible from the side, for easy replacement
