The 2023 Yamaha YZ450F is an impressive update that promises to inspire a new generation of MX champions. We're excited to share that we've made some improvements to the stock system, utilizing the perfect tube diameter and length in combination with our RS-12 to add power and torque across the entire spectrum of the new YZ450.
Our efforts have resulted in an 8% increase in max horsepower and a remarkable 13% boost in max torque, with the new RS-12 system unlocking some key power in just the right places. Despite these enhancements, the handling characteristics of the new YZ chassis remain intact, creating a fun and exciting ride.
In addition to performance, the RS-12 system also boasts machined joints on key tube junctions for a clean interface, a built-in resonator chamber on the muffler, a matte carbon fibre end cap, and a low-volume PTF sound insert. Please note that the spark arrestor is sold separately.
We're proud to say that the RS-12 system was designed, developed, and made in the USA.
