Manufacturer reference: GKA8837T (or SPGKA8837T) ā Spark Konix EVO (3/4 system), half-line kit for sports bikes.
The Spark Konix EVO kit is a high-performance half-line system designed to replace the original silencer and catalytic converter while remaining compatible with the original collector. It uses the titanium Konix EVO silencer, characterised by its compact design and extreme lightness. This system is exclusively developed for competitive use on closed circuits and does not have road approval.
Finish: titanium connecting pipe + titanium Konix EVO silencer.
Compatible models: Kawasaki ZX-10R (2021-2025).
Approval: not approved (compliant with FFM competition noise standards).
Weight: 1.6 kg (a massive weight reduction of -4.8 kg compared to the 6.4 kg of the original assembly).
Sound level: 107 dB.
Soundproofing: dB killer not included (sold separately).
On the track, this Konix EVO configuration offers an extremely punchy sound and a significant weight saving on the rear end, improving the handling of the Kawasaki ZX-10R (2021-2025). This kit allows for complete liberation of the gas flow after the collector, providing a sharper engine response and a clean racing aesthetic.
(Note: Installing this system with catalytic converter removal ideally requires an optimisation of the engine mapping to ensure optimal performance).
