Kawasaki Versys 650 And Vulcan S 650 Oxygen Sensor, Air Fuel Ratio Lambda O2

Keep your Kawasaki running cleanly and efficiently with this oxygen sensor designed for the Kawasaki Versys 650 and Vulcan S 650. This heated, lambda O2 sensor uses a piezoelectric sensing element to continually monitor exhaust oxygen levels and feed real-time data to your bike’s ECU. The result is a precise air–fuel ratio that improves combustion, boosts fuel efficiency, and reduces emissions, helping your engine perform at its best across daily rides, highway cruising, and spirited weekend trips.

Designed for compatibility with Kawasaki Versys 650 (KLE650) from 2015 to 2019 and Kawasaki Vulcan S 650 from 2015 to 2019, this sensor aligns with OEM specifications using part numbers 21176-0775, 211760775, and 21176 0775. Whether you’re rebuilding, restoring, or performing routine maintenance, you can trust this sensor to deliver reliable, model-specific performance without guesswork.

Main Description

Engineered for precision, this oxygen sensor integrates seamlessly into your Kawasaki’s exhaust system to measure the oxygen content of the exhaust gas and relay data back to the engine control unit. With a heated design, it maintains optimum operating temperature for quick response and stable readings, even after cold starts. This translates to smoother idle, improved throttle response, and consistent fuel economy — especially valuable when riding in varying terrains and weather conditions.

Why replace with IWOKPHD’s sensor? The part is built to mirror OEM fit and performance, reducing the risk of incompatible sensors or uneven readings that can trip error codes or affect engine timing. Easy installation means you can get back on the road quickly, with confidence that the air-fuel ratio will be managed accurately, helping your bike stay compliant with emission standards and deliver dependable performance ride after ride.

Benefits & Tips

• Benefit 1: Restored fuel management. A healthy O2 sensor maintains optimal air-fuel balance, improving combustion efficiency and potentially reducing fuel consumption over time.
• Benefit 2: Smoother operation after mods. If you’ve upgraded exhaust or intake components, a fresh sensor helps your ECU adapt quickly, preserving smooth power delivery.
• Tip: Verify fitment. Compare your OEM part number to 21176-0775, 211760775, or 21176 0775 before ordering. If unsure, send your part number or original product photos for confirmation (we respond within 24 hours).
