Kawasaki Versys-X Versys X 300 O2 Sensor Lambda Probe, 4-Wire

Main Description

Upgrade or replace your Kawasaki Versys-X Versys X 300 O2 sensor with this 4-wire heated Lambda Probe from WEIDA AUTO PARTS. Designed as a precise, direct-fit sensor for Kawasaki Versys-X 300 (KLE300) models from 2017 to 2019, this part is matched to OEM number 21176-0839 and built for reliable, long-lasting performance. Originating from Japan, it combines solid construction with a responsive sensing element to provide accurate air-fuel readings to the engine management system.

With a piezoelectric sensor element and an integrated heating circuit, this probe reaches its operating temperature quickly, delivering stable, fast-responding oxygen readings. That means smoother idling, more consistent throttle response, and improved emission control as the ECU fine-tunes the fuel mix. A precise, well-maintained O2 signal helps your bike run cleaner and more efficiently, reducing unnecessary fuel consumption over time and helping keep your engine in its optimal operating window.

This O2 sensor is tailored for the Versys-X 300’s specific exhaust and engine layout, ensuring a reliable replacement that maintains the bike’s performance characteristics and diagnostic compatibility.
