In proportion, that is the largest weight reduction in this whole catalogue relative to the machine it goes on — and the 3.3 PS on a 37 PS engine is close to a nine per cent gain, which no litre bike in this range comes near.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3.1 kg against the standard 8.2 kg: 5.1 kg and 62.2 per cent less\u003c\/li\u003e\n\u003cli\u003e40.0 PS, up from 37.2 PS — a gain of nearly nine per cent\u003c\/li\u003e\n\u003cli\u003eComplete system with a carbon fibre muffler outer sleeve\u003c\/li\u003e\n\u003cli\u003eOne part number covering twelve model years\u003c\/li\u003e\n\u003cli\u003ePure racing sound output\u003c\/li\u003e\n\u003cli\u003eNo road approval — circuit use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSmall Engines Gain the Most\u003c\/h2\u003e\n\u003cp\u003eA 321 cc twin has very little headroom, and Yamaha's standard exhaust spends most of it on emissions and noise compliance. Removing the whole system and replacing it with a straight-through racing design recovers a proportion of power that a 200 PS superbike simply does not have available.\u003c\/p\u003e\n\u003cp\u003eBoth the power and the torque gain land at 11,550 rpm, which on this engine is where it is being ridden on a circuit. This is a track part for a track use case, and it behaves like one.\u003c\/p\u003e\n\u003ch2\u003eTwelve Model Years, One System\u003c\/h2\u003e\n\u003cp\u003eYamaha has left the R3 platform's exhaust route essentially untouched since 2014, across the MT-03 roadster, the YZF-R3 and the Japanese YZF-R25. One part number covers all of them, from 2014 through 2026.\u003c\/p\u003e\n\u003cp\u003eThat is unusual and worth knowing: a used R3 bought cheaply takes the same system as a current one.\u003c\/p\u003e\n\u003ch2\u003eWhat the Weight Means Here\u003c\/h2\u003e\n\u003cp\u003eOn a 250 kg tourer, five kilograms is a rounding error. On a 170 kg lightweight it is roughly three per cent of the whole motorcycle, taken from high on the right-hand side where it does the most damage to how quickly the bike changes direction.\u003c\/p\u003e\n\u003cp\u003eThis is the rare case where a rider will notice the weight before they notice the power.\u003c\/p\u003e\n\u003ch2\u003eThe Bike That Racing Series Are Built On\u003c\/h2\u003e\n\u003cp\u003eThe R3 is the machine behind a long list of one-make racing series, because it is cheap, reliable and slow enough that riders learn lines rather than horsepower. Those grids are full of machines running exactly this kind of exhaust.\u003c\/p\u003e\n\u003cp\u003eIf you are preparing an R3 for a cup series, check your regulations before ordering — some championships specify the standard system, and others allow a full replacement.\u003c\/p\u003e\n\u003ch2\u003eNot for the Road\u003c\/h2\u003e\n\u003cp\u003eAn MT-03 or R3 is very often somebody's first motorcycle, held on an A2 licence. This system has no road approval, and fitting it to a road-registered bike puts the registration at risk. It belongs on a track machine.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-Y3R3-APC covers the Yamaha MT-03, YZF-R3 and YZF-R25 from model year 2014 through 2026.
