YAMAHA XSR125 2021-2026 - Akrapovic Exhausts System - S-Y125R13-HBFGT
£952.00
Model Compatibility
- Yamaha XSR125 (2021–2026)
- Yamaha XSR125 Legacy (2022–2026)
Note on Lineup Compatibility: While this exhaust bolts cleanly onto the 124cc VVA engine block shared with sibling models like the MT-125 and YZF-R125, the S-Y125R13-HBFGT part number utilizes a specifically swept underbelly mid-pipe, structural hanger brackets, and a conical silencer form designed exclusively to trace the retro geometry of the XSR chassis. It is not cross-compatible with the sharper lines of the MT or R-series variants without custom fabrication.
Key Performance Specifications
- Road Legality: Fully Euro 5 and Euro 5+ street-legal with integrated EC/ECE type approval. Unlike Akrapovič's modular setups, a high-efficiency 600 cpsi catalytic converter is built directly inside the center loop of this kit from the factory.
- Materials: High-grade stainless steel header loops paired with a premium, lightweight titanium outer muffler body sleeve.
- Weight Reduction: Saves 2.2 kg over the heavy single-piece factory original assembly, yielding an approximate 41.6% weight reduction on the scales.
- Performance Maximisation: Delivers an extra 0.3 hp (+0.2 kW) at 8,900 rpm and 0.3 Nm of torque at 9,000 rpm, explicitly smoothing out the VVA cam transition curve.
- Tuning Requirements: Complete plug-and-play installation. Because backpressure limits map precisely to standard factory compute tracking, no ECU remapping or re-flashing is required to safeguard the motor or prevent check engine dashboard lights.
