That gap does not buy a lighter or freer silencer — the two are the same case, the same materials and the same construction.\u003c\/p\u003e\u003cp\u003eWhat it buys is the absence of a homologation. For a motorcycle that is only ridden on closed circuits, that is a reasonable saving. For a registered Z900 it is not a saving at all, because the exhaust cannot legally be used — and forty euros is a very small amount to give up a road approval for.\u003c\/p\u003e\u003ch2\u003eWhen the Racing Version Is the Right One\u003c\/h2\u003e\u003cp\u003eThere are two situations where it genuinely is. The first is a dedicated track bike that will not be registered again, where the certificate has no value. The second is a market outside the EU where the Euro5+ approval means nothing anyway.\u003c\/p\u003e\u003cp\u003eEverywhere else, look at the homologated number. Spark sells both because both markets exist, not because one is a better silencer.\u003c\/p\u003e\u003ch2\u003eWhat Is in the Box\u003c\/h2\u003e\u003cp\u003eThe Konix Evo here is built exactly as the approved one: titanium case, titanium interior, titanium fitting and a carbon fibre end cap. Spark calls the construction ultralight, and the figures for this range bear it out at 1.7 kg against a 4.3 kg standard silencer.\u003c\/p\u003e\u003cp\u003eThe carbon fibre heat shield for the connecting pipe is supplied, as it is with the homologated versions. Installation is quick and needs no other changes to the motorcycle.\u003c\/p\u003e\u003ch2\u003eWhy the Konix Evo Suits This Bike\u003c\/h2\u003e\u003cp\u003eSpark says the case was drawn with angular lines that blend with the Z900, and in front of the motorcycle that holds up. Kawasaki's naked is built from hard creases and flat surfaces; a soft cylindrical silencer sits awkwardly beside it.\u003c\/p\u003e\u003cp\u003eThe Konix Evo picks that language up, and the carbon end cap — cut at an angle rather than square — finishes it. Whether the silencer carries a certificate or not, the shape is the same argument.\u003c\/p\u003e\u003ch2\u003eThe Weight Is the Same Too\u003c\/h2\u003e\u003cp\u003eSpark quotes 1.7 kg for its Euro5+ Z900 slip-ons against a 4.3 kg standard silencer, and the racing listing is the same component. Two and a half kilos come off the tail either way.\u003c\/p\u003e\u003cp\u003eOn a naked bike that mass sits low, to one side and well behind the centre — the least useful place it could be. It is the single cheapest handling change available on a Z900, and it does not depend on which listing you buy.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eKawasaki Z900, 2025 through 2026.
