Spark's Grid-O system takes more than half the weight out of the MT-07's exhaust, and the coiled TIG-welded collector it does it with is the part people photograph.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRacing full system for the Yamaha MT-07, XSR700 and Tracer 700.\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel headers with a hand TIG-welded collector.\u003c\/li\u003e\n\u003cli\u003eGrid-O silencer in full titanium with the perforated mesh cap.\u003c\/li\u003e\n\u003cli\u003edB killer included.\u003c\/li\u003e\n\u003cli\u003e3,1 kg against 7,2 kg standard: 4,1 kg saved.\u003c\/li\u003e\n\u003cli\u003eNo road approval — Spark states racing use only.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe Collector Is the Point\u003c\/h2\u003e\u003cp\u003eSpark says it in as many words: the TIG-welded collector is striking, and it is a distinctive element both aesthetically and technically. The welding is not decoration — hand-welding is how Spark gets the manifold lengths it wants without the compromises a pressed and machine-welded joint would force.\u003c\/p\u003e\u003cp\u003eOn a parallel twin the length of each header matters more than on a four, because there are only two pipes to work with. Spark sized them to optimise performance, and left the seams visible because on a naked motorcycle the collector is on show.\u003c\/p\u003e\u003ch2\u003eMore Than Half the Weight\u003c\/h2\u003e\u003cp\u003e7,2 kg standard, 3,1 fitted. On a motorcycle that weighs around 184 kg wet, four kilos out of the exhaust is a proportion you do not usually get from a single component — and the MT-07 is a bike whose whole character is built on being light.\u003c\/p\u003e\u003ch2\u003eThe Grid-O Silencer\u003c\/h2\u003e\u003cp\u003eFull titanium, with the perforated mesh outlet cap that gives the design its name. It is the same silencer family Spark took to Moto2, scaled to a 689 cc twin, and it arrives with the dB killer already in the box rather than as an extra to order.\u003c\/p\u003e\u003cp\u003eThat last point separates this system from Spark's newer R7 kits, where the dB killer is an optional insert.\u003c\/p\u003e\u003ch2\u003eRacing Use Only\u003c\/h2\u003e\u003cp\u003eSpark's installation note is in capitals: not recommended for road use, for racing use only. There is no homologation certificate and no catalytic converter. Fit it to a machine used on circuits.\u003c\/p\u003e\u003ch2\u003eWhich Motorcycles\u003c\/h2\u003e\u003cp\u003eSpark's article page lists the MT-07 from 2014 to 2020 and from 2021 to 2026, plus the Tracer 700 from 2016 to 2020. Spark's own photography for this code also shows the XSR700, and the 2026 price list groups the number with the XSR 700 — so we list it here.\u003c\/p\u003e\u003cp\u003eThe price list additionally groups this number under the YZF R7. Spark's article page does not mention the R7, and Spark builds two dedicated R7 systems (GYA8895T and GYA8896T), so we have left the R7 off this article. If you have an R7 and want this system specifically, ask us and we will check it with Spark first.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha MT-07 (2014-2026), XSR700 and Tracer 700 (2016-2020).
