    Looking at some used and new bikes, and I kind of want that feature (I know there's a lot on here that would say, forget it, but I want it) :huh

    TPM is short for Tire Pressure Monitoring. Has a different name in the catalog. My understanding is that is difficult to add after the factory. My dealer said that it had to come from the factory. I was fortunate and had TPM on my unit.

    RDC is the other name. How much is it worth to you. Personally $0 but I am not buying or selling.Some the have to have it and will pay dearly for it, look at the price of after market set ups.

    The install of the actual hardware is very straightforward, especially if you are doing a tire change anyway. The problem is that the retrofit is not officially supported by BMW NA, so you will need to find a dealer who is willing and able to reprogram the computer. I have heard of other people having it done, and Joel Wiesman's regional BMW rep knew of several as well. We were never able to figure out any details, though.

    The parts are about $600 from BMW. If you want to give it a shot, I have both sensors and the control module and will sell them for half that. Don't need them any more as I put spoked wheels on my F650GS twin.

    His bike had the RDC as a factory option and was adding the alarm.
    To the best of my understanding (I was until May 1 2010 a BMW master certified motorcycle technician at a top 5 volume dealer) the RDC can only be added to a very small vin range. You are correct it is not currently supported by BMW. However if you have a bike that falls in the vin range and you have a dealer you keep the old GT1 program discs they can scrub the current version software out of the GT1 and reload the old version. From the point the operation is fairly straight forward. If you bike is outside the vin range you will need to hack into the GT1 software to allow the insulation.
    If there is another way I would be very interested in how it has been done.

    The great state of confusion
    I talked to the master tech at my local dealership and he said he'd try but offered no promises....

    Then he told me that the battery in the wheel sensor units can not be replaced and that when the battery dies you have to buy a new sender unit for ~$200 USD. :eek1 The batteries last 3 - 5 years based on use.

    While I like the idea of the RDC/TPM and really would like to have it integrated into my dash... I'm kinda glad I didn't get it now.

    I'll probably get one of these when I have time to focus on it:

    I have this TPM on my 800GS:

    www.doranmfg.com it works perfectly and is transferable to other bikes rather than sold with the bike.

    What about these things?

    Little pressure monitors, $5 each? Anybody tried them? I was going to buy a couple and see how well they work, but I can't remember what the recommended tire pressures are!

    They work great and I had those on all my vehicles until I changing brake pads on my K100RS. I was cleaning the rotors with brake clean and some of the brake clean dripped onto the pressure monitor valve cap, within a few seconds the plastic cap came loose from the metal part and the tire went flat in 30 seconds. I thought about the cap breaking loose on the road and decided that I would go back to the old valve caps.

    I have the Doran unit on my GSA and agree that it works great. I can get the pressures without having to move or ride the bike. The true lazy man's tire pressure system.

    Does the Doran unit take temperature into account? Or are you basically just waiting until you have cool tires to get a real number, and using that TPM as an OH $#!^ gauge any other time?

    The Doran does not use a temperature algorithm and I prefere it that way. On my GSA my rear pressures are always two or three psi highter than the front as they warm up.

    It's great on trips. In the morning I turn on the key and withing a few minutes I know exactly what my pressures are.
