Spark's underseat racing kit for the 2025 Speed Triple, with carbon end caps — the least expensive way into the conversion, and the only version of it that has no metal on show.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRacing underseat twin kit for the Triumph Speed Triple 1200 RS and RR, 2025 to 2026 only.\u003c\/li\u003e\n\u003cli\u003eTwo Dyno silencers with carbon fibre end caps.\u003c\/li\u003e\n\u003cli\u003e4.1 kg against 7.4 kg standard — 3.3 kg saved.\u003c\/li\u003e\n\u003cli\u003eThe original catalytic converter remains fitted.\u003c\/li\u003e\n\u003cli\u003eNo ECU remapping required.\u003c\/li\u003e\n\u003cli\u003eMust be used with the dB killer installed.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe Price Ladder\u003c\/h2\u003e\u003cp\u003eSpark offers this kit with carbon caps or with red anodised aluminium ones, and charges around a hundred and ten euros more for the metal. Nothing else changes between them: same silencers, same weight, same routing, same restrictions.\u003c\/p\u003e\u003cp\u003eWhat the anodised version adds is a machined object — 6000-series aluminium cut on a five-axis CNC, perforated, with different radii inside and out. Whether that is worth the difference is a question about the motorcycle rather than about the exhaust, and both answers are reasonable.\u003c\/p\u003e\u003ch2\u003eA Lighter Standard Exhaust to Beat\u003c\/h2\u003e\u003cp\u003eThe 2025 Speed Triple's standard system weighs 7.4 kg, against 7.7 kg on the earlier bike. Triumph made the original lighter, so the saving this kit delivers is 3.3 kg rather than the 3.6 kg it achieves on MY21-24.\u003c\/p\u003e\u003cp\u003eThat is worth knowing if you are comparing figures between the two generations. The Spark kit weighs the same in both; it is the exhaust it replaces that changed.\u003c\/p\u003e\u003ch2\u003eRace Configuration, Standard Electronics\u003c\/h2\u003e\u003cp\u003eSpark leaves the catalytic converter on the motorcycle, so the lambda arrangement is untouched, no remap is needed and no error lights appear. What the kit replaces is everything behind the converter.\u003c\/p\u003e\u003cp\u003eThe dB killer is not optional here — Spark states in capitals that the exhaust must be used with it installed. Two short cases exiting under the seat of a 1,200 cc triple is not a quiet arrangement without one.\u003c\/p\u003e\u003ch2\u003eWhere Carbon Earns Its Place\u003c\/h2\u003e\u003cp\u003eThe end cap is the one point on an exhaust where carbon fibre is doing a real job rather than decorating one. It sits at the coolest part of the system, after the gas has given up most of its heat, and carries no load beyond closing the case.\u003c\/p\u003e\u003cp\u003eUnder the seat, where these outlets point rearwards and are fully exposed, a matt woven surface reads very differently from a bright machined one. It is the quieter of the two finishes on a motorcycle that is not quiet in any other respect.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Speed Triple 1200 RS and RR, 2025 through 2026 only.
