Frequently Asked Questions

Will this fix a check engine light related to O2 sensors?

If your code points to the rear O2 sensor circuit, this replacement can resolve it. Have your bike diagnosed first to confirm which sensor is failing.

Do I need to clear codes after installation?

After installing a new O2 sensor, the bike's ECM may need to relearn. Some riders use a diagnostic scanner; others ride normally and codes clear after a few ignition cycles.

Yes — no modifications or adapters needed. Bolt-in replacement for the OEM rear sensor.

What's the difference between Cycle Pro and OEM Harley sensors?
