Spark's Moto GP silencer is the most compact of the five it offers on the R1's D.65 titanium collector, cut steeply at the outlet and derived from prototype racing — and, like the Grid-O, it sits above the decibel limits of the French championship and the Endurance World Championship.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium D.65 system with the Moto GP silencer.\u003c\/li\u003e\n\u003cli\u003eShort case with a steep outlet cut, taken from prototype practice.\u003c\/li\u003e\n\u003cli\u003e114 dB — Spark's own figure for this system, against the 102 dB limit of the French championship and the EWC.\u003c\/li\u003e\n\u003cli\u003eTitanium collector developed with international championship teams.\u003c\/li\u003e\n\u003cli\u003eVisible weld seams on the connecting pipe.\u003c\/li\u003e\n\u003cli\u003eYamaha R1 and R1M, 2015 to 2025.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat a Short Silencer Costs and Buys\u003c\/h2\u003e\u003cp\u003eBuys: the look. On an R1 the Moto GP case ends well before the tail does, which leaves the rear of the motorcycle visually open in a way the longer silencers do not. It is the most obviously race-derived option on the bike.\u003c\/p\u003e\u003cp\u003eCosts: decibels. Absorption is a function of volume, and a shorter case has less of it, which is why this and the Grid-O sit on the loud side of Spark's own dividing line. The packing and the perforated core have to work harder over a shorter distance, and there is a limit to how far that goes.\u003c\/p\u003e\u003ch2\u003eCheck the Circuit\u003c\/h2\u003e\u003cp\u003eSpark splits its R1 silencers into two groups and publishes which is which: Force and Force Evo comply with the French championship and Endurance World Championship limits, MotoGP and Grid-O do not. That is a manufacturer telling you plainly where its product cannot be used, and it is worth taking at face value before ordering.\u003c\/p\u003e\u003cp\u003eFor a rider in a series with no ceiling, or in a country where none is enforced, none of this matters and the Moto GP is a fine choice. For anyone booking track days across several countries, GYA8880T with the Konix Evo or GYA8881T with the Force Evo will cause fewer problems at the gate.\u003c\/p\u003e\u003ch2\u003eOn the Weight Figure\u003c\/h2\u003e\u003cp\u003eSpark lists this code with two different weights across its own pages — 3.5 kg against 10.0 kg on one, 2.7 kg against 10.0 kg on another. We are not going to choose between two manufacturer figures and present the result as fact. The comparable titanium systems on this collector are quoted at 3.5 kg; if you need a confirmed number for this exact configuration, ask us and we will request 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 same collector carries the Konix Evo (GYA8880T) and the Grid-O (GYA8871T); the bare titanium manifold on its own is GYA8880R.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone.
