Key Performance Specifications
- Road Legality: Strictly not street legal. It functions as a non-homologated competition race system meant solely for closed-course track circuits or off-road competition.
- Full Titanium Build: Crafted entirely from high-grade, lightweight titanium alloys across the headers, link sections, and outer muffler body sleeve. It incorporates different material thicknesses across sections to reinforce crash protection zones without adding bulk.
- Weight Reduction: Shaves 20.4% (0.9 kg) off the total mass of the factory single-piece assembly.
- Performance Gain: Yields a sharp increase of 2.4 hp (1.8 kW) at 10,600 rpm and 1.5 Nm of torque at 10,500 rpm. It features an integrated header resonance chamber to smooth out throttle snap and boost bottom-end responsiveness.
- Sound Regulation: Features a unique profiled muffler surface that creates a deep, full exhaust note while remaining strictly compliant with FIM trackside competition noise limits.
- Tuning Requirements: True plug-and-play track installation. It runs smoothly out of the box with no mandatory ECU fuel mapping changes required
