The stock exhaust system is heavy and restricted, limiting the bike's ability to pull through deep loam and carry speed over jumps. The Yoshimura RS-12 Full System was specifically developed over 24 months of factory-level racing to solve this exact pain point, uncorking the RM-Z250 engine to provide a broader, more aggressive power curve and significantly improved over-rev.\u003c\/p\u003e\n\n\u003cp\u003eConstructed with \"Factory Quality\" precision, the RS-12 features an asymmetrical profile that maximizes internal muffler volume for better sound management while ensuring your Suzuki RM-Z250 has ample clearance for the rear tire and brake caliper. This system utilizes precision-machined joints that provide a superior 360-degree seal, preventing power leaks and ensuring a long-lasting, exacting fit. By pushing the muffler body forward, the RS-12 centralizes weight, further enhancing the Suzuki’s world-class handling and making it even more agile in the ruts.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eRace-Proven Gains:\u003c\/b\u003e Increases overall power and torque across the entire RPM range for better drive out of corners.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eFactory Quality Machined Joints:\u003c\/b\u003e Ensures a superior, exacting fit with a 360-degree contact surface for maximum durability.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eWeight Centralization:\u003c\/b\u003e Tapered muffler body moves mass forward to complement the RM-Z250’s agile handling.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003ePrecision Taper Fit (PTF):\u003c\/b\u003e Patent-pending insert ring makes installing spark arresters or sound inserts effortless.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eMatte Carbon Fiber End Cap:\u003c\/b\u003e \"Works\" look with an inner-cap mounted design for increased durability and easier servicing.\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 Suzuki RM-Z250 is known for its precise handling, and exhaust mounting can actually affect chassis flex. When installing your RS-12, start all bolts by hand first to ensure everything is aligned, then torque them to spec starting from the header and working your way back to the muffler. This prevents \"binding\" the system, which can cause premature cracking and unwanted vibration through the frame.\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\u003e2019 - 2026\u003c\/td\u003e\n\u003ctd\u003eSuzuki\u003c\/td\u003e\n\u003ctd\u003eRM-Z250\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\u003eDoes this system require a different fuel map?\u003c\/b\u003e\u003cbr\u003e\nA) While the RS-12 will run on the stock Suzuki mapping, using the \"Rich\" (Grey) coupler provided with your bike or an aftermarket ECU will help you get the most out of the increased exhaust flow.\u003c\/p\u003e\n\n\u003cp\u003eQ) \u003cb\u003eHow much does the Yoshimura RS-12 weigh?\u003c\/b\u003e\u003cbr\u003e\nA) The full RS-12 system weighs in at 8.5 lbs, providing a weight reduction over the 8.7 lb stock system while significantly improving performance.\u003c\/p\u003e\n\n\u003cp\u003eQ) \u003cb\u003eCan I add a spark arrester to this exhaust?\u003c\/b\u003e\u003cbr\u003e\nA) Yes, the RS-12 features a PTF insert ring that is compatible with Yoshimura spark arresters (sold separately) for riding in off-road areas that require them.\u003c\/p\u003e\n\n\u003cdiv style=\"margin-top: 20px;\"\u003e\n  \u003ca href=\"\/search?q=Suzuki+RM-Z250+Engine\"\u003eSuzuki RM-Z250 Engine Performance\u003c\/a\u003e | \n  \u003ca href=\"\/search?q=Suzuki+RM-Z250+Exhaust\"\u003eRM-Z250 Exhaust Systems\u003c\/a\u003e | \n  \u003ca href=\"\/search?q=Yoshimura+RS-12+Repack\"\u003eYoshimura Maintenance Kits\u003c\/a\u003e\n\u003c\/div\u003e\n\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003eMoto-House MX – Choice of Champions\u003c\/b\u003e – is located in Clermont\/Montverde, FL.
