WR250R / X O2 sensor voltage European and Australian owners

Hi all,

I am hoping one person could measure their O2 sensor voltage whilst riding at a steady cruise to see what they get. I used tiny metal wire tidies stripped and poked them into the O2 sensor connector. You have to push them quite far with pliers. Then I put the multi meter on the dash. Just watch the wires on the exhaust.. I added tape to avoid any shorts. I guess you could also use wire taps.


This is for European and Australian bike owners which have an O2 sensor factory fitted.


A big thank you!
