I am trying to buy a new replacement oxygen sensor cable for my 2020 Tenere 700.  Can anybody suggest a supplier or the Yamaha part number.  Trying to find it on the internet has been a nightmare.  Any help would be appreciated

Are you looking to replace the sensor with the short pigtail attached to it or a section of the wiring harness that it plugs into? 
 

Here is the “Exhaust” section for the 2021 model on Partzilla:

O2 sensor is: BW3-8592A-10-00

 

That’s for the American 2021. If your bike is a 2020 because you’re in Europe here’s the link to Yamahas Parts Catalogue, just put in your info and pull up the parts diagrams for your bike:
