Fitment:
2025 CRF 250R/RX
The 2025 Honda CRF250R has been unveiled, and when it comes to Honda Motocross Racing exhaust systems nobody even comes close to Yoshimura R&D of America.
The newest CRF250R boasts a new chassis, airbox and ECU configuration. Our engineering and development team has had their nose to the grindstone with Team Honda HRC to squeeze every drop of performance out of the new 250. With our new RS-12 Signature Series full system, we achieved a peak HP gain of 2% over stock while the peak torque gain came in at 5%.
Some of the features of the new RS-12 include:
Hydroformed Muffler
This is the first of a new generation RS-12 profile exhaust system featuring weight reducing hydroformed technology. This technology allows to maximize available space for a tailored fit while minimizing material usage. Hydroforming removes many of the limitations of conventional metal forming methods allowing for a stronger and lighter muffler. This new sleeve also incorporates a deep draw one-piece resonator further improving durability.
Carbon Faced Machined Joint
Our new Carbon Faced Machined Joint no longer requires the use of anti-seize. This is accomplished by impregnating the surface of the stainless steel joint with carbon atoms. The result is a reduction in wear over the life of the joint by reducing friction.
Header Resonator
Developed in cooperation with the Honda HRC Team, our header resonator isn't just there for looks, it allows us to maximize power across the spectrum, while enhancing rider connectivity.
The new RS-12 for the 2025 Honda CRF250 also comes with an INS-31-K sound insert installed. This insert not only produces an ear pleasing exhaust note, it also makes the best power for the new Honda.
Proudly developed with the help of the Honda HRC race team in the USA
