2005 R1 Oxygen Sensor?

I am so confused. Every fuel injected vehicle I have ever known has at least 1 oxygen sensor.

Does this bike (2005 R1) have an oxygen sensor or no? And if not, how is that even possible? How can the ECU make adjustments and whatnot?

No O2 sensor on that one. It’s all open loop (predetermined fuel metering based on other settings). Lots of vehicles that have O2 sensors don’t use them 100% of the time either. Idle and near WOT are generally predetermined open loop fuel metering rather than using the O2 signal to adjust AFR.

Are you having a problem or just wondering for general info?
