Spark EVO5 Stainless Steel Complete LineRef : SPK0217 / SPGYA8835IOM

Manufacturer reference: GYA8835IOM — Spark EVO5 (Full system), road-legal exhaust system.

This full Spark system has been developed to enhance Yamaha's three-cylinder platform (CP3). Featuring the characteristic geometric design silencer of the EVO5 range, this "IOM" (Inox Homologated) version stands out with its fully stainless steel finish. It incorporates the necessary catalytic elements to comply with pollution and noise regulations, allowing for legal use on public roads under Euro 3 standards.

• Finish: stainless steel collectors (AISI 304 stainless steel) + EVO5 silencer in stainless steel.

• Compatible models: Yamaha MT-09 (2014-2020) / XSR 900 (2016-2020).

• Specificity: complete replacement system designed on a dynamometer to optimise the engine performance of the three-cylinder while radically modernising the side aesthetics of the bike with its 100% stainless steel casing.

• Homologation: road-legal (compliant with European emission and noise standards Euro 3, which de facto validates FFM sound checks for potential access to the track). (Technical note: the homologation certificate is not updated for the Euro 4 standard applicable to models from 2017).

Dynamically, this full system transforms the behaviour of the Yamaha MT-09 and XSR 900. Although the exact weight is not communicated by the manufacturer, replacing the bulky original silencer with this new assembly significantly lightens the lower part of the machine. This centralisation of mass makes the bike more agile, while the angular shape of the silencer perfectly integrates with the lines of the roadster. The sound of the CP3 engine is enhanced, becoming more metallic and raspy, while remaining within legal limits.

(Note: The installation of this road-legal system, as it includes a catalyst, does not require mandatory reprogramming of the original injection mapping).
