The approved one keeps a catalyst in the line and carries a homologation. This article is the other: the same side-passage layout and the same Konix Evo silencer, with the catalyst left out.\u003c\/p\u003e\u003cp\u003eWhat that buys is 414 euro against the low-mount approved kit GHO8838TOM, and a system that is unrestricted through its whole length. What it costs is the road registration.\u003c\/p\u003e\u003ch2\u003eWhich of the Four\u003c\/h2\u003e\u003cp\u003eSpark's range for this motorcycle runs from 1.726 to 2.140 euro and from 3,7 to 6,5 kg, and only one article in it is road legal.\u003c\/p\u003e\u003cp\u003eThat makes the decision unusually simple. If the motorcycle is registered and stays registered, GHO8838TOM is the only candidate. If it does not, the question becomes weight against silencer shape — and this is the cheapest way in.\u003c\/p\u003e\u003ch2\u003eSide Passage\u003c\/h2\u003e\u003cp\u003eSpark describes this layout as recalling the side routing of the more track-focused machines. The silencer runs along the flank rather than tucking low under the engine, which changes the outline of a CB650R more than a silencer swap normally does.\u003c\/p\u003e\u003cp\u003eOn a CBR650R with the full fairing, it is the more visible of the two positions.\u003c\/p\u003e\u003ch2\u003eThe Konix Evo\u003c\/h2\u003e\u003cp\u003eThe Konix Evo is Spark's newer silencer shape — angular, wedge-sided, with a carbon end cap. Against the round Grid-O used on the other systems for this bike, it is the more contemporary of the two designs.\u003c\/p\u003e\u003cp\u003eBoth are full titanium. The choice between them on this motorcycle is a matter of shape and of which system layout you want behind it.\u003c\/p\u003e\u003ch2\u003eWhat Spark Engineered Into the Range\u003c\/h2\u003e\u003cp\u003eThe development behind these systems went into the collector diameters and the 4-2-1 conic sections, aimed at the mid-range rather than peak power. That work is shared across the four articles; only what comes after the manifolds changes.\u003c\/p\u003e\u003cp\u003eRemoving the catalyst on this version opens the gas path further. It also makes the motorcycle louder than the approved kit, by a margin Spark does not quantify for the racing versions.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eHonda CB650R Neo Sports Café and CBR650R, 2019 to 2025.
