SalvaHD Stage 1 Smart Tuner

The RBW Skull Snap is an affordable and effective solution for boosting horsepower and torque on nearly all Euro-5 motorcycles, including all 2021 to present Euro-5-compliant Harley-Davidson models. This compact device fine-tunes the O2 sensor readings, allowing the fuel injection system to optimize the air-fuel mixture for peak performance, especially when using open exhaust systems or high-flow air cleaners. It also prevents error codes related to O2 sensors during operation. Installation couldn’t be simpler, just plug it into the OBD2 connector and you're ready to ride!
Note: The rear O2 sensor(s) must remain connected to the wiring harness but do not need to be physically installed in the exhaust system.
