YOSHIMURA RS-12 FULL EXHAUST SYSTEM (TI/CARBON CAP) HONDA CRF250R 2025-

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 airbox and ECU configuration. Our engineering and development team has had their nose to the grindstone along with Team Honda HRC Progressive to squeeze every drop of performance out of the new 250. With our new RS-12 Signature Series titanium full system, we achieved a max HP gain of 8.0% over stock while the max torque gain came in at 9.0%.

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.
• Header Resonator - Developed in cooperation with the Team Honda HRC Progressive, 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.
