    concur!

    here's a new fun thought: the 2021 model BMWs are receiving some updates to meet the EU standards. i thought i read that the bikes will no longer be able to fully turn off ABS as a result (or something to that effect). if true, sounds like 2020 models (which are slim pickins) are more valuable. unless the US variants will maintain their ABS disengage function.

    That is likely the reason you need the "Coding Plug" installed to activate the "Pro" modes.

    I think i read somewhere that the ABS thing was only going to be applied to a couple bikes like the R1250 R/RS. I could be wrong though.

    Yes, from the 50's with a stick shift hand shifter lever (!) and drum brakes!
    Locking up the brakes was the least of my worries...

    As for turning ABS off or not. The need for turning ABS off was it's inability to perform properly when riding on soft surface. The wheels needs to more or less lock up in order to penetrate the top level and dig into a more firm surface underneath.

    For the newest generation of ABS, found on the latest 1200GS, 1250 as well as the 850, if you select the Enduro mode, the ABS is readjusted to where it allows the front wheel to be locked slightly longer prior to release in order to allow for the wheel to penetrate the soft top layer. Hence, there is no longer the need to turn the ABS off when riding on gravel roads. If using Enduro PRO mode, the ABS function for the rear wheel is deactivated.

    Agree, it's not a 250 motocross bike, not many are going to ride it like one.
    But you bring up a good point, when you guys lock up the rear with the brake, I'm assuming you also pull the clutch in?? There's no built-in slippage to it for that is there?

    The bikes have a "Slipper" clutch but that is for if you downshift too fast to prevent the rear wheel from locking up.

    ... and is it effective to keep the engine from stalling at full wheel lockup?

    No it is designed to work the opposite and not allow the wheel to lock up with the engine braking from downshifting. If you are in the correct gear you really don't need to worry about stalling the engine because once you set up the drift and let off the brake the wheel will roll and get the engine spinning again.

    Are you saying that the correct technique for sliding the rear is down shifting (which will not completely lock the rear wheel), and not applying the foot brake (to full lock)?
    Or did we get sidetracked on something that wasn't really my question...

    Ok, makes sense mostly. Just surprised about the "engine temporarily locking up" being ok.
