With countless hours of track and dyno testing, the KX450 responded well to our RS-12 with crisp and clean usable power that is up across the entire rpm spectrum. The result, max HP was up 9.6% and torque was up as well at 5.6%.
Yoshimura RS-12 will improve your experience on the green machine and decrease dB level from stock noise levels. Just what the doctor ordered.
Proudly designed, developed and made in the USA!
