O2 Sensor E5 Eliminator Kit – Euro 5 Compatible
The O2 Sensor E5 Eliminator Kit is designed to replace the factory oxygen sensor in your motorcycle’s exhaust system.
This kit is compatible with motorcycles that comply with the latest emissions standards, including Euro 5 models.
Motorcycle manufacturers install O₂ sensors to help maintain a strict stoichiometric air-fuel ratio. While this is ideal for emissions control, it often compromises performance—especially when the bike is tuned for track or off-road use. Simply removing the O₂ sensor typically causes an FI warning light or fault code.
To meet modern emissions compliance, manufacturers have introduced more advanced ECU strategies, making bypassing the sensor more difficult.

Our new-generation O2 Sensor Eliminator Kit is built using compact, PCB electronics that mimic the signal of the original sensor. This ensures error-free operation when the O₂ sensor is removed, with no check engine lights or adverse ECU behaviour.
Key Features:
-
Enhances throttle response and low/mid-range torque
-
Allows proper operation of aftermarket tuning modules or ECU remaps
-
Ideal for use with exhaust systems that lack an oxygen sensor port
-
Can be used to bypass or replace a faulty factory O₂ sensor
-
This kit includes the correct number of eliminators and stainless exhaust plugs needed for one motorcycle as pictured.
