Massive Power Gains
Up 9.3% hp gains at 6,200 rpm and up to 9.6% torque is achieved at 6,200 rpm. Even all the way up to the top our hybrid RS-12 system has substantial performance.
Significant Weight Savings
Our new RS-12 hybrid system comes in with less weight than stock thanks to our power producing titanium/aluminum muffler.
Header Resonator
Our new Yamaha YZ450F system boasts a volume specific header resonator that not only looks like a work of art, it helps put the power where its needed.
Muffler Resonator
Inside the front cap of the power producing RS-12 is another resonator that enhances the power characteristics of the new YZ.
109dB Capable
If you're a professional racer you know how important passing the FIM and AMA sound regulations can be. Our new RS-12 system is built with that in mind and can pass the 109db sound standard with an optional INS-39-K.
Easy Install!
The new RS-12 is easy to install due to the where the header uses its machined joint.
