Spark's high-mount racing kit puts a Grid-O titanium silencer behind stainless manifolds and a stainless fitting, with nothing between them that has to pass an emissions test.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRacing full system for the Honda CB650R and CBR650R.\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless manifolds and stainless fitting.\u003c\/li\u003e\n\u003cli\u003eGrid-O silencer in titanium, high mounting.\u003c\/li\u003e\n\u003cli\u003e4,8 kg against 10,7 kg for the standard system.\u003c\/li\u003e\n\u003cli\u003eNo catalyst.\u003c\/li\u003e\n\u003cli\u003eRacing part, not approved for road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere the Six Kilos Are\u003c\/h2\u003e\u003cp\u003eThe standard exhaust on a 650R is four steel primaries, a collector, a catalytic section in its housing, and a steel silencer. Spark replaces the whole run with stainless manifolds and a titanium can, and the catalyst does not come back.\u003c\/p\u003e\u003cp\u003e4,8 kg against 10,7 is a 5,9 kg saving — more than half the assembly. On a motorcycle in this class that is a meaningful fraction of what a rider can realistically remove.\u003c\/p\u003e\u003ch2\u003eWhich Article Is Which\u003c\/h2\u003e\u003cp\u003eFour systems, one platform, and the names do not make the differences obvious. GHO8838TOM is the approved one, low-mounted, with a catalyst box. GHO8839T is the racing Konix Evo. This is the racing Grid-O. GHO8841T is the same idea with a titanium link pipe instead of a stainless one.\u003c\/p\u003e\u003cp\u003eThe weights run 6,5 · 5,7 · 4,8 · 3,7 kg in that order, against 10,7 standard. Price does not follow weight: the lightest is not the dearest, and the approved one is.\u003c\/p\u003e\u003ch2\u003eThe Manifolds Are Shared\u003c\/h2\u003e\u003cp\u003eAll four systems use the same AISI 304 stainless manifolds, with the collector diameters and 4-2-1 conic sections Spark developed for this engine. What changes across the range is everything behind them.\u003c\/p\u003e\u003ch2\u003eStainless Fitting, Not a Catalyst Box\u003c\/h2\u003e\u003cp\u003eThe difference between this article and the approved GHO8838TOM is what sits between the manifolds and the silencer. There, a box containing Spark's own catalyst. Here, a plain stainless fitting.\u003c\/p\u003e\u003cp\u003eThat is 1,7 kg of the difference between the two kits, and all of the difference in their legal status.\u003c\/p\u003e\u003ch2\u003eThe Grid-O\u003c\/h2\u003e\u003cp\u003eThe Grid-O is the round Spark silencer with the mesh outlet cap, in full titanium with visible TIG welds. It is the same design that was on the 2020 Moto2 world championship-winning machine.\u003c\/p\u003e\u003cp\u003eIts large diameter is deliberate on a four-cylinder — Spark uses it where the aim is to give the four-cylinder sound room rather than to shorten it.\u003c\/p\u003e\u003ch2\u003eHigh Mounting\u003c\/h2\u003e\u003cp\u003eThe silencer sits high on the flank rather than low under the engine. On a naked CB650R that puts it in the eyeline; on a faired CBR650R it changes the profile of the tail.\u003c\/p\u003e\u003cp\u003eIt also clears the ground better, which matters on a bike that spends its weekends being leaned over.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eHonda CB650R Neo Sports Café and CBR650R, 2019 to 2025.
