The 1020009/B Lambda Sensor is a genuine Royal Enfield replacement component used in the exhaust and engine management system of compatible Interceptor 650 and Continental GT 650 motorcycles.
Also commonly referred to as an oxygen sensor or O2 sensor, the lambda sensor measures oxygen levels in the exhaust gases and sends feedback to the ECU. This feedback helps the engine management system regulate the air-fuel mixture and support emissions control.
It is suitable for replacement when the original lambda sensor has been diagnosed as faulty, damaged or otherwise requires replacement.
