Yamaha builds the YZ250F for motocross, the YZ250FX for cross-country and the WR250F for enduro around the same 250 single, and Akrapovic covers all three with this part number.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTitanium complete system for the 2024 to 2026 250 Yamahas\u003c\/li\u003e\n\u003cli\u003e3.39 kg instead of 4.22 kg — 0.83 kg less\u003c\/li\u003e\n\u003cli\u003e38.7 PS at 12,500 rpm against 38.2 standard\u003c\/li\u003e\n\u003cli\u003eTorque 24.7 Nm, up from 24.5\u003c\/li\u003e\n\u003cli\u003eFits YZ250F, YZ250FX and WR250F alike\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eThree bikes, one engine\u003c\/h2\u003e\n\u003cp\u003eThe differences between the three are gearing, suspension, a kickstand and lighting — not the engine or the exhaust routing. That is why one system serves all three, and why a rider moving from a YZ to a WR does not need a second pipe.\u003c\/p\u003e\n\u003cp\u003eYamaha's reversed-cylinder design puts the intake at the front and the exhaust at the back, which gives the header a longer, straighter run than on a conventional layout. Akrapovic works with that rather than against it.\u003c\/p\u003e\n\u003ch2\u003eWhat 830 grams does on a 250 enduro\u003c\/h2\u003e\n\u003cp\u003eAn enduro rider picks the bike up more often than a motocross rider does. Under 0.9 kg sounds modest until it is being lifted out of a ditch for the fourth time in a lap, and the mass is coming off the top and the side rather than the middle.\u003c\/p\u003e\n\u003cp\u003eThe power gain is half a horsepower. Akrapovic does not pretend otherwise, and neither do we — the case for this system is weight and response, not a dyno chart.\u003c\/p\u003e\n\u003ch2\u003eNot for the road\u003c\/h2\u003e\n\u003cp\u003eClosed course competition only, no EC or ECE approval. A WR250F is road-registerable in some markets in standard trim; this system removes that basis. Fitting it makes the bike a competition machine.\u003c\/p\u003e\n\u003ch2\u003eEnduro and motocross ask different things\u003c\/h2\u003e\n\u003cp\u003eA WR250F spends hours at part throttle in the woods; a YZ250F spends thirty minutes at full noise on a groomed track. The same exhaust serves both because the engine is the same, but the wear pattern is not: an enduro bike collects mud in the header shielding and a motocross bike collects impacts.\u003c\/p\u003e\n\u003cp\u003eIf the bike is used in the woods, the thing worth checking after each ride is the header where it passes the frame — that is where packed mud holds heat and where a titanium wall will discolour first.\u003c\/p\u003e\n\u003ch2\u003eHow Akrapovic arrives at its figures\u003c\/h2\u003e\n\u003cp\u003eAkrapovic measures on its own computer-controlled chassis dynamometers, standard bike against modified, same day, same conditions. That is why the gains published across this catalogue look modest compared with what some manufacturers claim: the comparison is honest and the baseline is a real standard motorcycle rather than a worn one.\u003c\/p\u003e\n\u003cp\u003eIt also means the figures are specific to the bike measured. A machine with a different air filter, a race map or a worn engine will not repeat them exactly, and Akrapovic does not pretend otherwise.\u003c\/p\u003e\n\u003ch2\u003eThree bikes, one order\u003c\/h2\u003e\n\u003cp\u003eBecause the system covers the YZ250F, the YZ250FX and the WR250F, a workshop that runs more than one of them stocks a single part number. For a club team that is a real simplification.\u003c\/p\u003e\n\u003ch2\u003eArticle number\u003c\/h2\u003e\n\u003cp\u003eAkrapovic lists this system as S-Y2MET17-FDHLTA for model years 2024 to 2026. Earlier 250 Yamahas take S-Y2MET15-CIBNTA (2019–2020) or S-Y2MET14-CIBNTA (2014–2018).\u003c\/p\u003e","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":53631830196490,"sku":"S-Y2MET17-FDHLTA","price":1137.75,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01_537cba9c-e0d5-4c31-8506-fe472eea161c.png?v=1788618205","url":"https:\/\/inter-pace.com\/en-om\/products\/akrapovic-evolution-line-titanium-yamaha-yz250f-s-y2met17-fdhlta","provider":"Inter-Pace","version":"1.0","type":"link"}
