The pair weighs 4.4 kg against 10.4 kg for the factory system.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTitanium racing collector (GBM8821R) combined with the 350 mm Force Evo silencer (GBM8824ST).\u003c\/li\u003e\n\u003cli\u003e4.4 kg against 10.4 kg standard — 6.0 kg saved.\u003c\/li\u003e\n\u003cli\u003eForce Evo is the restrained one of Spark's race silencers: the rib along the titanium case runs into a carbon end cap.\u003c\/li\u003e\n\u003cli\u003eSupplied with the racing hanger that carries the silencer off the chassis, plus the complete mounting kit.\u003c\/li\u003e\n\u003cli\u003eSame collector as the Konix Evo and Grid-O systems — the silencer is what changes.\u003c\/li\u003e\n\u003cli\u003eFits S1000RR, M1000RR, M1000R and, per Spark's listing, the S1000R.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Materials\u003c\/h2\u003e\u003cp\u003eThis is sold as a pair of part numbers rather than a single system code, and that is not an accident of the catalogue. The collector is the expensive half and the half that stays with the bike; silencers are consumable in racing terms — they get crashed, repacked and swapped when a series changes its noise rule. Spark builds three that bolt to this one collector, so the pair notation tells you exactly what you own and what you can change later.\u003c\/p\u003e\u003cp\u003eThe Force Evo case carries a single longitudinal rib. It looks like styling and it is not: a thin titanium shell needs stiffening across its span, and the rib provides it while converging neatly into the lines of the carbon end cap. Inside, the perforated tube and inner end cap are titanium too.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Sound\u003c\/h2\u003e\u003cp\u003eSpark quotes 104 dB for the Force Evo on this collector, against 107 dB for the Konix Evo and 114 dB for the Grid-O. Three decibels does not sound like much written down; at a circuit with a hard 105 dB limit it is the difference between riding and loading the van.\u003c\/p\u003e\u003cp\u003eThe collector geometry comes from Spark's championship work — CIV, CEV, British Superbike, the Isle of Man TT and the Endurance World Championship all run the same pipework.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSpark's own notes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFull system for racing use.\u003c\/li\u003e\n\u003cli\u003eNot compatible with passenger footpegs.\u003c\/li\u003e\n\u003cli\u003eThe mounting kit includes the holder that fixes the silencer to the original rear frame.\u003c\/li\u003e\n\u003cli\u003eCompatible with the original fairings and with original or aftermarket radiators.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eBMW S1000RR (2019-2026), M1000RR, M1000R and S1000R.
