We developed the RS-4 in the R&D lab called the Motocross track. The RS-4 boasts its own resonance chamber and utilizes its volume and a unique baffling system to create the sound and power that is purely Yoshimura.
With 450's it's not all about creating more power, it's about creating more usable power and the RS-4 makes it happen. Max power is increased by 2.3% and max torque is increased by 1.2% throughout the power curve. Grip it and rip it!
