The Akrapovič E-B12R7/1 is a stainless steel header designed to support improved exhaust flow and optimized performance on compatible motorcycle applications. As part of the Akrapovič B12R7 exhaust system family, this header is engineered for reliable integration with the corresponding exhaust components and provides a durable upgrade over the original exhaust header when application-specific fitment is confirmed. The manufacturer part number and vendor part number are both E-B12R7/1.
The header incorporates an exhaust valve designed to improve rideability at lower engine speeds. This feature helps support smoother low-RPM operation while maintaining the performance characteristics expected from an Akrapovič exhaust system. The stainless steel construction offers dependable resistance to heat and corrosion, making the component suitable for demanding street and performance riding conditions. The B12R7 system designation identifies the applicable Akrapovič product family; verify the exact motorcycle model, model year, engine configuration, and related exhaust components before installation.
Remapping the engine control unit is recommended after installation. ECU calibration can help prevent a check engine light warning and allow the motorcycle to take full advantage of the revised exhaust flow, supporting optimized throttle response and overall engine performance. Professional installation is recommended to ensure correct header alignment, exhaust valve operation, sensor placement, and connection to the rest of the exhaust system. For proper fitment, compare the motorcycle’s original equipment configuration with the Akrapovič application guide and confirm compatibility for the intended motorcycle model. This product is supplied under the AKRAPOVIČ brand with part number E-B12R7/1.
