It is the same design language as the ribbed cases on the larger bikes, drawn tighter for a 400.\u003c\/p\u003e\u003cp\u003eThe practical effect is the same: a formed sleeve is stiffer than a plain one, so the wall can be thinner without the case ringing at the frequencies a screaming four produces.\u003c\/p\u003e\u003ch2\u003e105 Decibels Is a Decision\u003c\/h2\u003e\u003cp\u003eSpark builds four exhaust configurations for the ZX-4RR and each meets a different noise brief. This one sits at 105 dB. The Konix Evo meets the British championship level, the 400 mm Force Evo build reaches 98 dB, and the Grid-O has no limit at all.\u003c\/p\u003e\u003cp\u003eIf your events publish a number, that number picks the silencer for you. If they do not, 105 dB on a 400 four is a genuinely good noise and this is the case most owners choose.\u003c\/p\u003e\u003ch2\u003eWhat Comes With the Complete System\u003c\/h2\u003e\u003cp\u003eOrdered as the full system GKA8852T, this silencer arrives with the chassis hanger for race use and a second hanger that keeps the passenger footpeg. As a group on its own it is the silencer and its fittings — if you are building from parts, check which hangers you already have.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eFits the Kawasaki ZX-4RR of 2023 through 2026 on any Spark collector for this motorcycle. Ordered as a complete system it becomes GKA8852T. If 105 dB is too loud for your paddock, the 400 mm case GKA8855ST is the quieter route; if noise is not an issue at all, look at the Grid-O system GKA8851T instead.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNot approved.
