Spark rebuilt this kit when Triumph revised the motorcycle's tail — same idea, same red anodised caps, different part number, and it will not fit the earlier bike.\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 red anodised, CNC-milled end caps.\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\u003cli\u003eSpark quotes 4.1 kg for this kit against a 7.4 kg standard exhaust.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy There Are Two Part Numbers\u003c\/h2\u003e\u003cp\u003eSpark lists GTR0106 for MY21-24 and GTR0109 for MY25-26, and marks each as compatible only with its own model years. The silencers are the same family; the routing that gets them under the seat is not.\u003c\/p\u003e\u003cp\u003eTriumph changed the tail section and the standard exhaust arrangement for 2025, and the standard exhaust the kit replaces went from 7.7 kg to 7.4 kg. Ordering by model name alone will get you the wrong box. Check the year on the registration document first.\u003c\/p\u003e\u003ch2\u003eThe Catalyst Stays\u003c\/h2\u003e\u003cp\u003eThis is the unusual part of Spark's racing kits for this motorcycle, and it is worth repeating because it changes what the purchase involves. The original catalytic converter is not removed. The ECU does not need remapping. No error lights appear.\u003c\/p\u003e\u003cp\u003eWhat the kit replaces is everything behind the converter, which is where the standard system's mass and bulk sit. The result is a race-configured motorcycle that has not been touched electronically and can be put back to standard without a workshop visit.\u003c\/p\u003e\u003ch2\u003eThe dB Killer Is Part of the Design\u003c\/h2\u003e\u003cp\u003eSpark states in capitals that the exhaust must be used with the dB killer installed. That is not advice about circuit limits — it is how the kit is specified to operate.\u003c\/p\u003e\u003cp\u003eTwo short cases exiting under the seat of a 1,200 cc triple, without an insert, is a great deal more noise than Spark intends this product to make. The insert is included in the design rather than offered as an accessory.\u003c\/p\u003e\u003ch2\u003eWhat the Milled Caps Are\u003c\/h2\u003e\u003cp\u003eThe Dyno's end caps are machined from 6000-series aluminium on a five-axis CNC. The perforation through each one removes weight, and the different radii on the inner and outer faces catch light from more than one angle — Spark describes the effect as reflecting sunlight like a real jewel.\u003c\/p\u003e\u003cp\u003eAnodising puts the red into the surface rather than onto it, so the machining stays visible through the colour. Under the seat, pointing rearwards, these are the most exposed outlets any exhaust gets on this motorcycle.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Speed Triple 1200 RS and RR, 2025 through 2026 only. The same kit with carbon end caps is GTR0109TC. For MY21-24 the equivalents are GTR0106TR and GTR0106TC. The homologated slip-ons for this model year are GTR0108TOM and GTR0108DOM.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone.
