Manufacturer reference: GKA8843T āSpark Grid-O (system 3/4), half-system kit for competition.
The Spark Grid-O kit is an ultra-light half-system designed to replace the original silencer and catalytic converter while remaining compatible with the primary collector. It consists of a titanium connecting pipe and the titanium Grid-O silencer. This system is exclusively developed for competitive use on closed circuits and does not have road approval.
Finish: titanium connecting pipe + titanium Grid-O silencer.
Compatible models:Kawasaki ZX-10R / RR (2021-2025).
Specificity: allows for the retention of the original passenger footpegs.
Approval: not approved (not compliant with FFM noise standards for French circuits due to excessive volume, even with the addition of a baffle).
Weight: 1.7 kg (a massive weight saving of-7.8 kg compared to the original 9.5 kg assembly).
Sound level: 113 dB.
Soundproofing: dB killer not included (sold separately).
On the track, this Grid-O configuration offers one of the most extreme weight/performance ratios in the Spark catalogue. The removal of the catalytic converter completely frees the gas flow for a much sharper throttle response, while the exceptional weight saving of nearly 8 kg at the rear transforms the agility of theKawasaki ZX-10R during angle changes. The sound is particularly aggressive, directly inspired by the standards of the world championship.
(Note: Installing this system with catalytic converter removal ideally requires an engine mapping optimisation to ensure optimal performance and mechanical reliability).
