Same D.65 diameter, same Force Evo silencer, same 6.7 kg off the motorcycle — and around five hundred and fifty euros less than the titanium versions, because the collector is AISI stainless steel.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eD.65 stainless steel collector with the Force Evo titanium silencer.\u003c\/li\u003e\n\u003cli\u003e4.1 kg against 10.8 kg standard — 6.7 kg saved.\u003c\/li\u003e\n\u003cli\u003eThe least expensive full system Spark builds for the R1.\u003c\/li\u003e\n\u003cli\u003eForce Evo stays within the 102 dB limit set by the French championship and the Endurance World Championship.\u003c\/li\u003e\n\u003cli\u003eVisible welds on the connecting pipe, as on the titanium systems.\u003c\/li\u003e\n\u003cli\u003eYamaha R1 and R1M, 2015 to 2025.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat Six Hundred Grams Costs\u003c\/h2\u003e\u003cp\u003eThe titanium-collector systems weigh 3.5 kg; this one weighs 4.1 kg. Six hundred grams, for roughly five hundred and fifty euros. Put like that the arithmetic looks unkind to titanium, and for a lot of riders it is — six hundred grams on a 200 kg motorcycle is a rounding error next to a tank of fuel.\u003c\/p\u003e\u003cp\u003eWhere titanium earns its money is in a class with a minimum weight, where every part is chosen on grams because the bike is already at the limit. If that is not your situation, this system delivers the same diameter, the same silencer and the same 6.7 kg saving for meaningfully less.\u003c\/p\u003e\u003ch2\u003eThe Quiet End of the Range\u003c\/h2\u003e\u003cp\u003eSpark states plainly which of its silencers comply with which limits, and the Force Evo is on the compliant side: within the decibel ceiling required by the French championship and by the Endurance World Championship. The MotoGP and Grid-O cases sit above it.\u003c\/p\u003e\u003cp\u003eFor a rider who books track days at several circuits a year without knowing each one's noise policy in advance, that is the practical argument for this configuration over the louder ones. A system you can always use beats a system that is marginally freer and occasionally turned away.\u003c\/p\u003e\u003ch2\u003eStainless in the Hot Section\u003c\/h2\u003e\u003cp\u003eThe collector is where the exhaust is hottest, which is the part of the argument that goes in stainless steel's favour rather than against it. AISI stainless holds up to sustained heat cycling without the surface change titanium develops, it tolerates the pressure-washing and trailering a track bike gets, and a stone off the front wheel dents it rather than cracking it.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R1 and R1M, 2015 through 2025, and the MT-10 and MT-10 SP, 2016 through 2026 — Spark lists this part for both. The titanium equivalents on the same D.65 diameter are GYA8880T with the Konix Evo, GYA8850T with the Moto GP and GYA8871T with the Grid-O.
