Spark GRID-O Titanium Full LineRef : SPK0218 / SPGYA8862T

Manufacturer reference: GYA8862T — Spark Grid-O (Full system), competition exhaust system.

This full Spark system has been developed for Yamaha's three-cylinder platform (CP3). It replaces the entire heavy original exhaust system. Unlike the homologated version (GYA8862TOM), this "T" (Titanium Racing) variant is devoid of restrictive catalytic elements to maximise engine performance. This system is exclusively reserved for closed circuit use and does not have road approval.

• Finish: stainless steel (AISI 304) headers and silencer box + ultra-compact Grid-O titanium silencer.

• Compatible models: Yamaha MT-09 (2013-2020) / MT-09 Tracer and Tracer 900 GT (2015-2020) / XSR 900 (2016-2020).

• Specificity: low mounting position retaining the original footprint under the engine. The minimalist design of the Grid-O silencer is directly inspired by the exhausts from the Moto2 World Championship.

• Approval: not approved (fully compliant with FFM competition noise standards for French circuits due to its well-contained volume).

• Weight: 5.3 kg (a weight saving of -3.1 kg compared to the original full system's 8.4 kg).

• Sound level: 93.5 dB at 5,000 rpm (manufacturer measurement, very close to the original system's volume of 93 dB).

• Soundproofing: dB killer not included (sold separately).

Dynamically, this full system transforms the behaviour and look of the Yamaha MT-09, Tracer 900 and XSR 900. The weight reduction of over 3 kg significantly lightens the lower part of the machine, centralising the masses and making it even more responsive and agile in cornering sequences. The adoption of the tiny Grid-O titanium silencer gives the bike a very aggressive "race" look while freeing up the gas flow. Despite its Racing orientation, the sound volume remains particularly controlled (93.5 dB) thanks to the effective upstream silencer chamber, offering a deep and throaty sound that enhances the CP3 engine without being deafening.

(Note: The installation of this decatalysed racing full system ideally requires a remapping of the injection mapping (ECU) to optimise the air/fuel ratio, ensure engine reliability, and exploit its full potential).
