Spark took a different route here.\u003c\/p\u003e\u003cp\u003eThe converter stays on the motorcycle. What the kit replaces is the section behind it, which is where the standard system's weight and bulk actually are. The consequence is a race-configured motorcycle that needs no dyno time, throws no error codes and can be returned to standard in an afternoon.\u003c\/p\u003e\u003ch2\u003eWhy the dB Killer Is Not Optional\u003c\/h2\u003e\u003cp\u003eSpark prints the instruction in capitals: use the exhaust with the dB killer installed. That is unusual wording for a racing product and it should be read as written.\u003c\/p\u003e\u003cp\u003eTwo short silencers exiting under the seat, on a 1,200 cc triple, produce a great deal of noise without an insert. Spark is not making a suggestion about circuit limits here — it is stating how this kit is intended to be operated. Take the insert out and you are outside what the manufacturer designed for.\u003c\/p\u003e\u003ch2\u003eModel Year Matters\u003c\/h2\u003e\u003cp\u003eSpark states this kit is compatible only with MY21-24. The 2025 Speed Triple got a revised tail and a different exhaust arrangement, and the equivalent kits for it are GTR0109TC and GTR0109TR.\u003c\/p\u003e\u003cp\u003eCheck the model year before ordering rather than the model name — RS and RR are both covered, but only for the earlier bikes. The two generations look similar and take entirely different parts.\u003c\/p\u003e\u003ch2\u003eThe End Caps, Again\u003c\/h2\u003e\u003cp\u003eThe Dyno silencers here carry the same end cap Spark uses across this range: 6000-series aluminium, milled on a five-axis CNC, perforated to save weight and cut with different radii inside and out so it catches light from more than one angle.\u003c\/p\u003e\u003cp\u003eUnder the seat those caps sit high and point rearwards, which is the most visible position any exhaust outlet gets on a naked bike. Red is the loudest of the finishes Spark offers, and here it has the best stage in the range.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Speed Triple 1200 RS and RR, 2021 through 2024 only. The same kit with carbon end caps is GTR0106TC. For MY2025 onwards the equivalents are GTR0109TR and GTR0109TC. The homologated slip-ons for this generation are GTR0105TOM and the GTR0104 twin range.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone.
