    I was considering buying a 2004-2007 R1200GS , but was concerned about the lack of being able to change the oil in the final drive. Apparently there is no filler or drain plug in some models. This seems ridiculous.
    I dont consider having to remove the rear wheel etc and fill through a abs sensor hole much fun.
    Does anyone know if BMW have returned to their senses and installed drain and filling holes like the older R1150gs models have?
    If so what 1200 year models have this capablility.

    Many threads on this subject, and you can still change the oil easily in the FDs with no drain plug on the bottom. Well, I guess easy is a relative term depending on your wrenching ability/interest and this is about a 15 minute job.

    Remove the rear wheel, remove the ABS/speedo sensor, remove the bolt that attached the top of the FD to the torque arm above the driveshaft housing and the FD pivots downward 90 degrees. Pull what now serves as the drain plug (positioned directly rearward before the FD is pivoted down) and drain the oil. Reinstall the plug, pivot the FD back up while re-engaging the driveshaft splined adapter to the FD input shaft splines, reinstall the bolt, refill FD through the sensor hole, reinstall the sensor and wheel and you're done.

    Late build model year 2007 bikes and after got the bottom drain plug.

    It's really a good chance to grease the final drive input splines. I have seen some so rusted that they could not be separated.

    Do it everytime you replace the rear tire, wheel is already off. Works out about right.

    I don't know what year they added the fill hole but it is on the left so you still have to remove the wheel.

    This may sway you yet...
    In order to get all the juice out, you have to drop the FD by unbolting it from the tele?lever. In order to do this and not break your wire for the ABS sensor, you have to remove the sensor anyhow. Since it's out at this point, pretend it's a fill hole and fill-er up. :D

    Any one know if the newer bikes which have a drain hole are filled the same way? 2012
    Removing the rear wheel looks like it is as no fill with wheel on.
    Approaching. A 600 mile oil change.

    New bikes have a drain plug in the bottom and a fill hole on the side closest to the wheel that is above the center of the drive. Seems like I remember it being at 10 to 11 o'clock or so. I always drop the drive the first time though to grease the driveshaft splines.

    On my '12 GSA the fill hole is at 3 o'clock when the wheel is off. If you lube spline then you can just fill thru speed sensor hole, since you'll have to remove it anyway.

    The new FD's hold 200ml of gear oil. Don't over fill it.

    Max sent a 207ml bottle of oil & sealing ring for the drain & fill hole & speed sensor it looks like. Doing the 600 oil change.

    On my 2009 12GS after trying several times to loosen it, I couldn't budge the fill hole bolt. I used the sensor hole instead! Just take your time, the fluid goes in very slowly!

    Also, after checking several sources, I couldn't find a consensus on the amount of fluid for my 2009 so I filled it with 200ml and hoped for the best. So far, so good!

    Anything with the vent from 2010 and up. Mine is a 2013 :evil BMW has changed it about 3 times, IIRC. From 180ml to 220ml and back to 200ml.

    My factory manual says 180ML, what does yours say?

    I measured what came out at my 600MI service and it was 200ml. I don't have a service manual, yet.

    That isn't a great way to determine the proper level. Some techs read the original spec in 04 and never again, still adding 220ml. Some fluid stays in place on the gears, which is why I suspect BMW specced 180ml. The dry fill was originally 250ml, with a wet fill of 220ml. BMW reduced the amount to 180ml in an effort (so it is surmised) to reduce overpressure and fluid pushing past the seals.

    IMHO, stick with 180ml. There is no harm in it.

    Any advice for getting these apart? Mine is tight, reefed on it for a bit with a big screwdriver and hammer to no avail. Put a bit of WD40 on the end of the shaft to see if that would help free it and no go.

    Thinking to cut out the boot - sorta needs replacing anyway - and stick a heat gun in there to try and help free it, but I obviously don't want to damage the U joint or anything...

    I would try a slide hammer first. If that doesn't work, and is very well should, you can use a screwdriver through the upper end of the swingarm boot and pry carefully.
