Spark Titanium force + titanium collector Full LineRef : SPK0206 / SPGYA8864T

Manufacturer reference: GYA8864T — Spark Force EVO 2019 / Step 2 (Full system), competition exhaust system.

This full Spark system has been specifically developed for the track, in close collaboration with teams competing in the world championship and national championships (CIV, FSBK). It replaces the entire heavy original exhaust system of the Japanese supersport to maximise mid-range torque and peak power. Unlike the steel version (ref. GYA8863T), this variant features fully titanium collectors for extreme weight reduction. This system is exclusively reserved for closed circuit use and does not have road approval.

• Finish: Full Titanium (racing titanium collectors + titanium Force silencer).

• Compatible models: Yamaha YZF-R6 (2017-2025).

• Specificity: "Step 2" architecture benefiting from machined connections (CNC) for optimal assembly and increased durability against vibrations and thermal stresses of competition.

• Approval: not approved (fully compliant with FFM competition noise standards for French circuits).

• Weight: 4.6 kg (a spectacular weight reduction of -5.7 kg compared to the 10.3 kg of the complete original system).

• Sound level: 102 dB.

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

On the track, this full system transforms the dynamics of the Yamaha YZF-R6 of the latest generation. Spark's R&D department has meticulously calculated the lengths, cones, and sizing of the collectors to ensure maximum engine efficiency. Combined with the Force silencer, the entire titanium setup offers a weight loss of nearly 6 kg, significantly enhancing the bike's agility during angle changes and heavy braking. It delivers a perfectly controlled supersport sound (102 dB) to pass technical checks without issues.

(Note: Installing this full racing system requires ECU reprogramming to optimise the air/fuel ratio, ensure engine reliability, and exploit its full potential).
