Does the 2025 V4RS now use wideband O2s?

Flow · Monday at 5:43 PM

Hey folks, do we know if the new V4 RS use 6 widebands now? Part number looks to be 55215541A.
Opps Mods, this should have been in the Multistrada or maybe Mechanical / Technical forum

How many people do you think will get their hands on an RS? I'd be surprised if one made it into the US at all.

The goal is to use the small form factor O2s for wideband tuning. Typical widebands are too big M18 there are Mini-LSU 4.9 (M16) and the BMW widebands are M14 but the Ducati ones look to be M12 which is the same form factor as the narrow band sensors. But the question is are they actually wideband like the BMWs or does this engine just use 6 narrow band sensors. 55215541A is the part number.

To be clear. This parts drawing above is for the Multistrada V4 RS. The European model has 4 narrowband O2 sensors, one in each cylinder. Some models in other countries have only 2 narrowband sensors, one for each cylinder bank. Looks like the drawing shows both configurations combined. The EU model have another 2 narrowband sensors, one after each catalyst brick.

Indeed,"Opps Mods, this should have been in the Multistrada or maybe Mechanical / Technical forum"

So no wideband O2s in the Ducati (VAG) stable as yet?

Just had Ducati tech support confirm, there are no wideband O2 sensors on any bikes as yet.

Does the 2025 V4RS now use wideband O2s?
