The Yamaha YZ450F has undergone significant changes in both motor and chassis refinements, and seems to be the 450 that many are choosing. It's no secret that the Yamaha YZ450F has a very good stock system that many competitors can't beat. Yoshimura spent a lot of R&D time in the dyno room and track to create their RS-4 Signature Series to what they think is the best aftermarket exhaust for the new YZ.
