Spark Custom Works Racing Complete LineRef : SPK0197 / SPGTR8804IOM

Manufacturer reference: GTR8804IOM — Spark Custom Works Hot Rod Evolution (Full 2-in-2 system), road-legal exhaust system.

This full 2-in-2 Spark system has been developed to enhance the classic lines of British twin-cylinder bikes while optimising their performance at low and mid-revs. Unlike strictly "Racing" versions, this "IOM" variant is installed while retaining the original catalysts to comply with pollution and noise regulations (Euro 4), thus allowing for completely legal use on public roads.

• Finish: stainless steel collectors (AISI 304 stainless steel) + double Hot Rod Evolution silencer in stainless steel.

• Compatible models: Triumph Bonneville T120 (2016-2024) / Street Twin 900 (2016-2024).

• Specificity: mounts directly onto the original catalysts. Note, the installation of this system is not compatible with the centre stand.

• Approval: road-legal (compliant with European Euro 4 standards, which de facto validates FFM sound checks for potential access to the track).

• Weight: 5.0 kg (a weight saving of -7.0 kg compared to the 12.0 kg of the original full system).

• Sound level: Data not provided (regulated by European approval).

• Soundproofing: baffle (dB killer) included as standard

Dynamically, this full system transforms the Triumph Bonneville T120 and the Street Twin 900. The spectacular reduction of 7 kg on the scales significantly lightens the machine, making it much more manageable in daily use and responsive in cornering sequences. The high-end Custom Works finish enhances the neo-retro style while offering a much more rewarding sound, all while remaining strictly legal.

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