SmartMoto O2 Sensor Eliminator Kit – KTM, HUSQVARNA & Gas Gas Models

Unlock smoother throttle response, improved low- and mid-range torque, and consistent engine performance with the SmartMoto O2 Sensor Eliminator Kit. Designed to replace the factory oxygen sensor, this plug-and-play solution allows your motorcycle’s ECU to run exclusively on its fuel map, without interference from the stock O2 sensor system.

Manufacturers install oxygen sensors to maintain a strict stoichiometric air-fuel ratio for emissions compliance. While ideal for street regulations, this can limit performance, especially when a motorcycle is tuned for track riding, off-road use, or fitted with aftermarket upgrades.

Removing the factory O2 sensor normally triggers an Fi warning light. The SmartMoto Eliminator Kit prevents this by accurately simulating the expected sensor signals. This allows complete removal of the O2 sensor system while keeping the ECU stable and error-free.

This kit is specially designed for motorcycles built to earlier emission standards such as Euro 2, Euro 3, and select Euro 4 models.

The SmartMoto Complete Set includes both the electronic eliminators and the required exhaust port plugs. Everything needed for full system removal is included—no cutting, splicing, or wiring modifications required
