Manufacturer reference: GYA8816COM — Spark Force (Full system), road-legal exhaust system.
This full Spark system has been developed to optimise the performance of the renowned three-cylinder (CP3) engine from the tuning fork brand. Unlike strictly "Racing" versions, this "COM" (Carbon Homologated) variant includes a special catalyst in the pipes to comply with pollution and noise regulations, thus allowing legal use on public roads (Euro 3 standard).
Finish: stainless steel collector (AISI 304 stainless steel) with catalyst + Force silencer in carbon fibre.
Compatible models: Yamaha MT-09 (2013-2020) / MT-09 Tracer and Tracer 900 (2015-2020) / XSR 900 (2016-2020).
Specificity: low position mounting (Standard mounting) close to the original location, with collector diameters specifically calculated by R&D to maximise engine torque.
Homologation: road-legal (compliant with European emission and noise standards Euro 3, which de facto validates FFM sound checks for potential access to circuits). (Technical note: the homologation certificate is not updated for the Euro 4 standard applicable to models from 2017).
Weight: 4.2 kg (which represents an excellent weight saving of -4.2 kg compared to the 8.4 kg of the original full system).
Sound level: Raw data not provided (volume regulated by European homologation).
Soundproofing: chicane (dB killer) included as standard (essential for road homologation).
Dynamically, this full system transforms the behaviour of the three-cylinder platform (Yamaha MT-09, Tracer 900 and XSR 900). The weight reduction halved (gain of 4.2 kg) significantly lightens the machine and centralises the masses, making it even more playful and agile in cornering sequences. The adoption of the Force silencer in carbon finish highlights the sporty spirit of the bike while freeing up gas flow for better acceleration. The whole system offers a rough and captivating sound that enhances the CP3 engine, all while remaining within the strictest legality.
(Note: The installation of this road-legal system, as it integrates a specific calibrated catalyst, does not require mandatory reprogramming of the original injection mapping).
