That is Spark's own comparison for this kit, and it comes with a silencer that measures inside the 102 dB required by the French championship and the Endurance World Championship — light and legal, which is a rarer combination than it sounds.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e3\/4 kit for the Yamaha R1 and R1M: titanium D.60 2-into-1 manifold plus titanium Force silencer.\u003c\/li\u003e\n\u003cli\u003e2.5 kg against 8 kg standard — 5.5 kg saved.\u003c\/li\u003e\n\u003cli\u003eWithin the 102 dB limit of the French championship and the Endurance World Championship.\u003c\/li\u003e\n\u003cli\u003eEliminates the catalytic converter, keeps the standard headers.\u003c\/li\u003e\n\u003cli\u003eCompatible with the passenger footrests, no extra bracket needed.\u003c\/li\u003e\n\u003cli\u003eD.60 — the diameter Spark optimised for the 2020-2023 model years.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFive and a Half Kilos\u003c\/h2\u003e\u003cp\u003eThe saving is worth taking apart, because the number is unusually large for a part that costs what this does. The standard section a 3\/4 system replaces is not just pipe: it contains the catalytic converter, a steel monolith in a steel housing, and it is the single densest object in a modern exhaust.\u003c\/p\u003e\u003cp\u003eRemoving it and replacing the surrounding pipework with titanium is why five and a half kilos come off a motorcycle that has not otherwise changed. And it comes off low and central, ahead of the rear wheel — the place where a rider feels a reduction as quicker settling between corners rather than as a lighter bike.\u003c\/p\u003e\u003ch2\u003eThe Case for the Plain Force\u003c\/h2\u003e\u003cp\u003eThe Force is Spark's long-running silencer: a clean cylindrical case with a straightforward mounting interface, no rib, no sculpting. Next to the Konix Evo and the Force Evo it looks like the cheap option, and in list-price terms it is.\u003c\/p\u003e\u003cp\u003eWhat it is not is the compromised one. Spark groups the Force with the Force Evo on the compliant side of its own decibel line — both clear 102 dB — so the plainer case gives up styling, not usability. If the point of the exercise is a lighter bike that can be ridden at any circuit that measures, this is the configuration that gets there for the least money.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eThe four standard headers stay in the fairing; only the section from the collector back changes. Spark lists this kit as compatible with the passenger footrests, and unlike the Konix Evo and Force Evo kits it needs no additional bracket. Keep the standard mid-section — refitting it is the only route back to a road-legal exhaust.
