The attached document describes the available OEM quality tire pressure sensors made by Schrader that can replace those used in pre-2022 BMW motorcycles (i.e. those having either the RDC or XRDC controllers) as a much more economical alternative to the overpriced BMW parts. 

 

Pretty sure the Bartec tool we had at the shop can program in the sensors if you don't have the GS911 or you don't want to go to BMW. 
 

There is a high probability that the Bartec tool can program the 33900 sensor to be compatible with BMW motorcycles but that programming is different than getting the BMW RDC/TPMS to recognize a new sensor ID. The GS-911 or the Motoscan app can be used to have the RDC/TPMS "learn" the new ID or the ID can be entered directly.

The new tool at work has BMW Bikes listed. It also connects to the vehicle and programs the sensors to the vehicle via the OBD 2 data port. I suspect that it will with the bikes as well. Haven't done a bike yet but lots of others. We have the Schrader sensors in stock and program/code them to what ever vehicle that is needed then program them to the specific vehicle. Don't see why it won't work with the bikes but have to try. Any victims out there ?? LOL 

EDITED

Disregard.

I only really relate to the car world, Pre 1995 we had OBD1 every manufacturer had their own proprietary system and connector. 96 on we have the mandated OBD2. the 16 pin connector that we find on the 17 and newer bikes. Several standardized pins for data and all the others for what ever the Manufacturer wants to use them for. BMW and other bike manufacturers adopted this standardized data port in 2017 ?? The round port had the same data pins but was proprietary to BMW Bikes of the day.  My Snap on scan tool can connect to my 2018 GSA and read basic codes using the generic data area.  I can buy the program for the tool to read more. I don't bother as I have a GS911. The GS 911 connects to the RDC to read out the codes and to also write the sensor ids to it as well. Well it probably connects to the Gateway in what ever ECU BMW decided to place it in. It then in turn communicates with what ever ECU you are asking for. The gateway is the interface built into all modern vehicles to interpret all the communication going on "CAN BUS" and is also  connected to the data port where we can pull info and sometimes change it. LOL . So no matter which tool you use you have to read the sensor id then input it into the ECU over writing the old sensor. We use to have to type the sensor id into the ECU then save it then activate the sensor for it to read it, some times it took a long road test for things to be happy. Easier now with the newer systems.  I suspect that  Bartec has bought the rights so their tool can access this part of the BMW system. May have been mandated or just reverse engineered, don't know, don't care. Still I would really like to try it out as a bunch of my side car friends are running Car wheels and the BMW TPMS sensor doesn't fit. So they have the warning happening. If I can program my universal sensor and install them I could solve that issue and be a hero. I just need a first victim LOL  Actually it is not an issue as I can over write sensors. So if you programmed it wrong you can go back and re-do it. Wasn't always the case.  I guess I could try on my own bike once one of my sensors fails.
Of course every thing will have changed again by the time that happens.We will have self programming sensors soon I bet.
Of course most manufacturers are going away from TPMS sensors and are using the ABS sensor to detect low tires. Bikes may do this soon too.
