Yes BMW has made chain driven bikes for a long time mostly their sport bikes and the adventure style ones, really about the only shaft driven they have are the cruisers and touring bikes. Years ago I looked at a 2015 F800r that the Yamaha dealer had gotten on trade, it was a very nice bike with low miles, did have ABS & heated grips, I had a 2013 Ninja 650 so this bike was only 2 years newer than what I had and to me was more of a sidegrade in the end so I didn't pursue it but sometimes I do look back and wonder about it, the ABS would've been a nice upgrade and the bike seemed a lot more comfortable than mine, the heated grips is ok but I don't really ride when it's cold out and I have warmer gloves to wear.
Really for me the biggest gripe at BMW right now is they have stopped selling service manuals so you can't find torque settings or much of anything.... they are basically claiming that their motorcycles are now too complex for the average person to work on it and due to technical and legal issues they are only allowing trained service mechanics to work on them.
