Spark's Trident 660 system pairs a racing catalyst with a pre-silencer box, and the approval comes from that combination rather than from a restricted silencer.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHomologated full system for the Triumph Trident 660, Tiger Sport 660 and Daytona 660, 2021 to 2026.\u003c\/li\u003e\n\u003cli\u003e5.0 kg against 8.1 kg standard — 3.1 kg saved.\u003c\/li\u003e\n\u003cli\u003eMoto GP silencer, short case with a large outlet.\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel collector and pre-silencer box, Scotch-Brite finish.\u003c\/li\u003e\n\u003cli\u003eRacing catalytic converter, heavily impregnated with noble metals.\u003c\/li\u003e\n\u003cli\u003eCertificate issued by the Italian Ministry of Transport.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCheck Your Homologation Number\u003c\/h2\u003e\u003cp\u003eSpark asks buyers to do something most manufacturers do not: confirm that the approval actually covers your motorcycle. The certificate lists specific homologation numbers, and Spark publishes them so they can be matched against the vehicle documents.\u003c\/p\u003e\u003cp\u003eThe numbers are e9*168\/2013-2020*11674, e9*168\/2013-2019*11675 and e9*168\/2013-2020*11675, all with engine code U. If your registration document shows one of those, the system is approved for your bike. If it shows something else, ask us before ordering rather than after.\u003c\/p\u003e\u003ch2\u003eOne Lambda Sensor or Two\u003c\/h2\u003e\u003cp\u003eSpark changed this system in production. Kits delivered before the end of February have a single lambda sensor socket; those from the beginning of March onwards have a fitting for the second sensor as well.\u003c\/p\u003e\u003cp\u003eTriumph's later machines run two sensors, so this matters. Current stock carries the dual predisposition — but if you are buying a system that has been sitting somewhere for a while, it is worth confirming which version it is before the fairing comes off.\u003c\/p\u003e\u003ch2\u003eWhere the Approval Lives\u003c\/h2\u003e\u003cp\u003eTwo components do the regulatory work. The racing catalytic converter is heavily soaked with noble metals, which is what lets it clean the gas without behaving like a restriction. The pre-silencer box ahead of the silencer takes the sharpness out of the pressure pulse.\u003c\/p\u003e\u003cp\u003eBetween them the silencer is left free to be what it is — a Moto GP case, short and wide at the outlet. That architecture is why a Spark homologated system sounds like a Spark system rather than like a muffled one.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Trident 660, Tiger Sport 660 and Daytona 660, 2021 through 2026.
