It is worth two minutes with the vehicle documents.\u003c\/p\u003e\u003cp\u003eThe numbers are e13*168\/2013*00097 and *00098 for engine RC74E; *00501, *00502, *00517 and *00518 for RH01E; *01837 to *01840 for RH15E; and e4*168\/2013*00122 to *00125 for RH03E. If the number in your papers is on that list, the approval applies to your motorcycle.\u003c\/p\u003e\u003ch2\u003eA Catalyst Built for the Job\u003c\/h2\u003e\u003cp\u003eThe kit does not delete the catalytic converter — it replaces it with Spark's own, in a light box ahead of the silencer. Spark describes it as a racing-cell catalyst heavily impregnated with noble metal: fewer restrictions in the gas path, enough conversion to stay inside Euro5.\u003c\/p\u003e\u003cp\u003eThat, plus work on the collector diameters and the 4-2-1 conic sections, is where the mid-range gain comes from. Spark is specific that the power curve was optimised in the middle rather than at the top.\u003c\/p\u003e\u003ch2\u003eThe Moto2 Silencer\u003c\/h2\u003e\u003cp\u003eThe Grid-O on this kit is the full titanium article with visible TIG welds — the same silencer that was on the 2020 Moto2 world championship-winning machine. Spark says so plainly rather than implying it.\u003c\/p\u003e\u003cp\u003eIts mesh outlet cap is the visual signature, and on a four-cylinder 650 the large diameter is what gives the sound its body.\u003c\/p\u003e\u003ch2\u003eOne Warning for Euro5+ Bikes\u003c\/h2\u003e\u003cp\u003eSpark states it in capitals: fitting this exhaust to a Euro5+ machine may bring on the engine warning light. The kit is built with a provision for the dual lambda sensor, but the later emissions generation is not what the approval was written for.\u003c\/p\u003e\u003cp\u003eOn a Euro5 CB650R it is a straightforward fit.
