This \"choked\" feeling translates to a loss of valuable over-rev and throttle response when you're trying to clear high-consequence triples or pull through deep loam. The Yoshimura RS-12 Full System is the ultimate solution, engineered to maximize the volumetric efficiency of the Honda powerplant, delivering a wider powerband and immediate snap off the gate.\u003c\/p\u003e\n\n\u003cp\u003eDeveloped through rigorous factory-level testing, the RS-12 utilizes \"Factory Quality\" precision-machined joints to ensure an airtight 360-degree seal, eliminating the power-robbing leaks common in lower-grade systems. The asymmetrical muffler profile not only manages sound for competition compliance but also provides increased clearance for the rear brake caliper and tire. With its tapered inlet design, the RS-12 shifts the weight of the exhaust forward, complementing the Honda CRF250RX’s nimble handling and making the bike feel lighter and more flickable in technical sections.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eEnhanced Throttle Response:\u003c\/b\u003e Optimized for the 2025-2026 engine to deliver immediate power delivery and increased over-rev.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eFactory Quality Machined Joints:\u003c\/b\u003e Precision-engineered connections for a perfect, durable fit and easier maintenance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eAsymmetrical RS-12 Profile:\u003c\/b\u003e Maximizes muffler volume while improving ground and brake caliper clearance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eMatte Carbon Fiber End Cap:\u003c\/b\u003e Innovative inner-mount design increases durability and simplifies repack intervals.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003ePTF Insert System:\u003c\/b\u003e Patent-pending Precision Taper Fit ring makes it easy to install or remove sound inserts and spark arresters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eMoto-House MX Pro Tip:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe 2025-2026 Honda frame is incredibly precise, and the new exhaust mounting points require exact alignment. When installing your RS-12, do not tighten any bolts fully until the entire system is loosely fitted from the header to the muffler. This allows the \"Factory Quality\" machined joints to seat perfectly, preventing stress on the exhaust flange and ensuring a leak-free seal for the life of the pipe.\u003c\/p\u003e\n\n\u003ctable width=\"100%\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f2f2f2;\"\u003e\n      \u003cth\u003eYear\u003c\/th\u003e\n      \u003cth\u003eMake\u003c\/th\u003e\n      \u003cth\u003eModel\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2025 - 2026\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCRF250R\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2025 - 2026\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCRF250RX\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eWill this system increase my Honda's horsepower?\u003c\/b\u003e\u003cbr\u003e\nA) Yes, the RS-12 is specifically engineered to increase horsepower and torque across the entire RPM range by improving exhaust flow over the stock system.\u003c\/p\u003e\n\n\u003cp\u003eQ) \u003cb\u003eDoes this exhaust include a spark arrester?\u003c\/b\u003e\u003cbr\u003e\nA) This system is a closed-course competition exhaust.
