Spark builds its Konix Evo kit for the ZX-4RR two ways — AISI 304 stainless at 1,536 euro, titanium at 2,214 — and this is the lighter half of that choice.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRacing full system for the Kawasaki ZX-4RR.\u003c\/li\u003e\n\u003cli\u003eTitanium 4-2-1 collector with CNC-machined connections.\u003c\/li\u003e\n\u003cli\u003eKonix Evo silencer, fully titanium including the inner end cap.\u003c\/li\u003e\n\u003cli\u003eCarbon end cap designed with a Maranello style centre.\u003c\/li\u003e\n\u003cli\u003eMounting kit with chassis hanger and passenger-footpeg hanger.\u003c\/li\u003e\n\u003cli\u003eRacing part, not approved for road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSix Hundred and Seventy-Eight Euro of Titanium\u003c\/h2\u003e\u003cp\u003eThat is the gap to the stainless version, GKA8850T, and the manifold is the only thing that changes. Silencer, connections, mounting kit and geometry are shared.\u003c\/p\u003e\u003cp\u003eWhether it is worth it depends on what the bike is for. On a machine that gets weighed at scrutineering, or one where the owner is chasing every kilo out of a 400, titanium in the longest and heaviest section of the system is the obvious place to spend. On a track-day bike it is a preference.\u003c\/p\u003e\u003ch2\u003eThe System That Won the Trophy\u003c\/h2\u003e\u003cp\u003eSpark's Konix Evo kit for this motorcycle was chosen to equip every ZX-4RR in the 2024 Kawasaki British Superteen Championship, run within the BSB. That is a one-make series, so the exhaust was not competing against alternatives — it was the specification.\u003c\/p\u003e\u003cp\u003eWhat it does tell you is that the design passed a season of identical machines under one set of eyes, which is a harder test of consistency than of outright performance.\u003c\/p\u003e\u003ch2\u003eA Silencer Drawn in Maranello\u003c\/h2\u003e\u003cp\u003eSpark had the Konix Evo's carbon end cap designed in collaboration with a style centre in Maranello, and says so plainly. The case is entirely titanium — sleeve and inner end cap both — and its volume is what lets the silencer meet the noise level imposed on British circuits.\u003c\/p\u003e\u003cp\u003eThe dB killer is not in the box. It is a separate article, G9999, and worth ordering with the system if your events measure.\u003c\/p\u003e\u003ch2\u003eFour Into Two Into One\u003c\/h2\u003e\u003cp\u003eThe collector is a 4-2-1 layout with diameters and tapers Spark designed and tested for this engine rather than scaling from a larger one. The connections are machined from solid and the compensators are sized rather than off-the-shelf — Spark attributes both details to its Superbike and Moto2 programmes.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eFull system: the standard 4-2-1 exhaust comes off entirely. Spark's mounting kit includes the hanger to the chassis for race use and a separate hanger that keeps the passenger footpeg, so the system can be fitted to a standard motorcycle without stripping the rear.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eKawasaki ZX-4RR, 2023 to 2026. The same system with a stainless collector is GKA8850T. The Force Evo alternatives are GKA8852T at 105 dB and GKA8855T at 98 dB, and the unrestricted Grid-O system is GKA8851T. The titanium collector on its own is GKA8851, the Konix Evo silencer group GKA8850ST.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone.
