This is the same Grid-O silencer proven on Moto2 and Superbike World Championship circuits, now available as a complete bolt-on solution for road and track use on your M1000RR.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium construction throughout — header, silencer body and end cap — combining extreme heat resistance with a significant weight reduction of 6.8 kg over the standard system.\u003c\/li\u003e\n\u003cli\u003eRace-proven Grid-O silencer design, directly derived from units run in Moto2 and WorldSBK competition without decibel restrictions.\u003c\/li\u003e\n\u003cli\u003eRemovable DB killer (part number G9980) included, giving you the flexibility to run a compliant setup or open it up for full track noise of approximately 114 dB at 5,500 rpm.\u003c\/li\u003e\n\u003cli\u003eCompatible with original BMW fairings and both standard and kit radiators, so installation does not require additional bodywork modifications.\u003c\/li\u003e\n\u003cli\u003eSupplied with a bracket for the original pillion footrests and a complete fitting kit including all exhaust springs — everything needed for a straightforward installation.\u003c\/li\u003e\n\u003cli\u003eHandcrafted in Italy, reflecting Spark's exacting quality standards and the same production process used for their top-level race programmes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Real-World Usability\u003c\/h2\u003e\u003cp\u003eChoosing a full system over a slip-on delivers the greatest possible return on investment for track-focused riders. Where a slip-on replaces only the silencer, the Grid-O full system replaces the entire exhaust path with titanium pipework, so the weight reduction and flow improvements are felt across the entire rev range. The titanium header and canister resist discolouration and corrosion far better than stainless alternatives, keeping the system looking purposeful even after sustained high-temperature use.\u003c\/p\u003e\u003cp\u003eThe removable DB killer is a practical feature that distinguishes this system for riders who use their M1000RR on both road and track. Install the G9980 insert for a more manageable sound level on public roads or at circuits with noise limits, then remove it for maximum flow and the characteristic 114 dB bark when conditions allow. An optional chassis bracket is also available separately, allowing the system to be further tailored to specific race or trackday configurations.\u003c\/p\u003e\u003ch2\u003ePerformance and Track Use\u003c\/h2\u003e\u003cp\u003eThe Grid-O's racing heritage means it was designed specifically for circuits without decibel restrictions, and the performance gains are concentrated where they matter most on track. The 6.8 kg mass reduction lowers the centre of gravity and reduces unsprung rotational mass at the rear, with a direct and perceptible effect on corner-entry stability and direction changes. To extract the full potential of the system, Spark recommends a dedicated race map or a bespoke dyno session — pairing the Grid-O with an optimised fuel map will unlock the complete throttle response improvement the system is capable of delivering.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis system is designed and manufactured specifically for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW M1000RR K66 — model years 2021, 2022, 2023, 2024, 2025 and 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eCompatible with original BMW fairings and both OEM and aftermarket kit radiators.
