Main Description

Meet the Air-Fuel Ratio O2 Sensor designed for Benelli motorcycles, including the TRK 502X, TRK 502, 502C, Leoncino 500, and Leoncino 500 Trail. This heating-type, piezoelectric oxygen sensor delivers precise oxygen readings to the engine control unit, helping your bike maintain an optimal air-fuel balance. With OEM numbers 319026280000, 319026-280000, and 319026 280000, it’s a direct replacement that fits the original mounting and electrical interfaces. Made in Mainland China by IWOKPHD, this sensor is built to endure the heat and vibration of riding, delivering reliable performance mile after mile.

Why it matters: accurate air-fuel ratio data helps the ECU adjust mixtures for better throttle response, smoother idle, and improved fuel efficiency. By preventing rich or lean conditions, the sensor protects the catalytic converter and reduces emissions, while helping your engine perform consistently across RPM ranges. This part is a practical upgrade for riders seeking restoration of factory performance or preventative maintenance to avoid degraded fuel economy and rough engine behavior.

Compatibility and care: this AFR/O2 sensor is intended as a precise replacement for the Benelli TRK 502 family and Leoncino 500 series. Always verify the part number before purchase to ensure a perfect fit with your bike’s electrical connector and mounting points.
