Hunter Lawrence found the changes so inspiring that led him to compete with the new machine in the last three rounds of AMA Pro Motocross.\u003c\/p\u003e\n\u003cp\u003eThe newest CRF450R boasts an all-new 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 450. With our new RS-12 Signature Series full system, we achieved a max HP gain of 3.7% over stock while the max torque gain came in at 1.3%.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSome of the features on the 2025 CRF450R\/RX RS-12:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHydroformed Muffler\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHydroformed Header Primary\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eImproved performance due to exact matching of the oval exhaust port, with a smooth internal transition from oval to round. Increased durability from a reduction in welded connections.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeader Resonator\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDeveloped 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCast Manifold\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBenefit - Increased strength, durability, easier installation and removal.\u003c\/p\u003e\n\u003cp\u003eThe new RS-12 for the 2025 Honda CRF450R\/RX also comes with an INS-32-K sound insert installed.
