Spark's own description of this kit is a system for anyone who wants to be noticed — and heard — and the weight figure backs the first half of that: 3,7 kg where the standard exhaust weighs 10,7.\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.\u003c\/li\u003e\n\u003cli\u003eRacing link pipe in titanium, TIG welded.\u003c\/li\u003e\n\u003cli\u003eGrid-O silencer in full titanium.\u003c\/li\u003e\n\u003cli\u003e3,7 kg against 10,7 kg for the standard system.\u003c\/li\u003e\n\u003cli\u003eRacing part — Spark states it is not recommended for road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe Titanium Pipe Is the Difference\u003c\/h2\u003e\u003cp\u003eThree of Spark's four systems for this motorcycle use a stainless section between the manifolds and the silencer. This one uses titanium, TIG welded and left visible.\u003c\/p\u003e\u003cp\u003eThat single change takes it from 4,8 kg — the figure for the otherwise comparable GHO8840T — down to 3,7. A little over a kilo, for 238 euro. It is the most expensive kilo in the range and the reason this article sits at the top of it.\u003c\/p\u003e\u003ch2\u003eWhere This Sits in the Range\u003c\/h2\u003e\u003cp\u003eSpark builds four systems for the CB and CBR 650R. Only GHO8838TOM carries an approval; the other three are racing articles, and this is the extreme end of them.\u003c\/p\u003e\u003cp\u003eThe step from GHO8840T to this one is 238 euro and 1,1 kg — the price of replacing a stainless link pipe with a titanium one. Whether that is worth it depends entirely on whether the motorcycle is weighed at scrutineering.\u003c\/p\u003e\u003ch2\u003eSeven Kilos Off a 650\u003c\/h2\u003e\u003cp\u003eTo put the number in context: a CB650R weighs around 200 kg ready to ride. Removing seven of those from the exhaust alone is close to what a full titanium system achieves on a much larger and much more expensive motorcycle.\u003c\/p\u003e\u003cp\u003eAll of it comes from the right-hand side and below the seat — mass that was working against the bike every time it changed direction.\u003c\/p\u003e\u003ch2\u003eSpark Is Explicit About the Use\u003c\/h2\u003e\u003cp\u003eThe article page carries a plain instruction: not recommended for road use, for racing use only. That is stronger wording than the usual not-approved note, and it is worth reading as written.\u003c\/p\u003e\u003cp\u003eThe reason is the combination — no catalyst, an unrestricted titanium link and a Grid-O with a large outlet. This is the loudest configuration Spark offers for the 650R.\u003c\/p\u003e\u003ch2\u003eWhat It Shares With the Rest\u003c\/h2\u003e\u003cp\u003eThe manifolds are the same AISI 304 stainless design as the other three systems, with the collector diameters and 4-2-1 conic sections Spark developed for this engine. The Grid-O silencer is the full titanium article with visible TIG welds, the same design used on the 2020 Moto2 championship-winning machine.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eHonda CB650R Neo Sports Café and CBR650R, 2019 to 2025.
