Skull Snap OBD2 RBW Tuner for 2021-Present Harley-Davidson Models

The RBW Skull Snap is an affordable and effective solution for increasing horsepower and torque on nearly all Euro-5 motorcycles, including all Euro-5 compliant Harley-Davidson models from 2021 to present.
This compact device precisely adjusts O2 sensor readings, allowing the fuel injection system to optimize the air-fuel mixture for maximum performance, especially when using open exhaust systems or high-flow air filters.
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 drive!
Note: Rear O2 sensors must remain connected to the wiring harness, but do not need to be physically installed in the exhaust system.
Fits all 2021 to present Harley-Davidson motorcycles equipped with a red OBD2 connector
