For this one the manufacturer publishes neither. Rather than estimate from a comparable part or repeat brochure language, this page says so plainly: there is no measured weight saving and no measured power gain to report.\u003c\/p\u003e\n\u003cp\u003eWhat is documented is the construction, the materials and the approval, and those are real. If a measured figure matters to your decision, ask us and we will put the question to Akrapovic before you order.\u003c\/p\u003e\n\u003ch2\u003eWhat an A1 Rider Can Expect\u003c\/h2\u003e\n\u003cp\u003eThe MT-125 and YZF-R125 sit inside the A1 licence class at 15 PS, and the law caps them there. A type-approved exhaust cannot lift a 125 past that limit without taking the homologation with it — so nobody should expect a meaningful power increase from this system, and none is claimed.\u003c\/p\u003e\n\u003cp\u003eWhat a full system changes on a small engine is the character: the whole exhaust path is replaced rather than just the silencer, which affects how the engine picks up and how it sounds. The YZF-R25, with 249 cc and around 35 PS, sits in the A2 class and has more room to respond.\u003c\/p\u003e\n\u003ch2\u003eWhat a Full System Means Here\u003c\/h2\u003e\n\u003cp\u003eThis is not a silencer swap. The headers, the collector and the standard catalytic converter all come off, and on a small bike with tight bodywork that is more work than the size of the machine suggests. Budget a workshop session rather than an evening in the garage.\u003c\/p\u003e\n\u003cp\u003eWhat comes back on is a complete titanium path from the cylinder head. On a 125 that is a large proportion of the motorcycle's exhaust system replaced at once, and it is why a Racing Line for a small bike costs what a slip-on for a much larger one does.\u003c\/p\u003e\n\u003ch2\u003eThe Approval Is Worth More on an A1 Bike\u003c\/h2\u003e\n\u003cp\u003eA 125 is often a first motorcycle, ridden to school or to work by someone who cannot afford a problem with the registration document or the insurer. A full system without type approval would put both at risk.\u003c\/p\u003e\n\u003cp\u003eThis one carries EC and ECE certificates, which is the whole reason it belongs in a road-bike catalogue rather than a track-only one.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-Y125R11-HZT covers the Yamaha MT-125, YZF-R125 and YZF-R25 from model year 2021 through 2026.
