What's up guys, haven't been on here in a long time. I was browsing, and saw this topic, and I can contribute. I bought a K1600B last October, and I own a 2012 Road Glide. I can saw that the BMW is by far a more fun bike than my HD. I have put 8k miles on my BMW since last October, and less than 500 on my RG. I typically ride my RG to the bar, and occasionally to appease my riding buddies that still ride HD's. When I ride the BMW they get a little "butt-hurt" because they can't keep up, but hold on, I digress. The BMW has so much tech that the HD can't compare. Hill hold, clutch-less shifting, electronic suspension settings on the fly, heated front and rear seats, heated grips, adjustable windscreen, the list goes on and on. My 6k service cost me $320, will take it back at 12k, haven't had to add oil yet (BMW oil is $20/quart). The bike is so comfortable, it's everything my RG isn't - good and bad. I've taken it to ROT and Lonestar Rally, and it's about the only BMW there. Oh, I paid $23k out the door. There is virtually 0 aftermarket for it, but I'm telling you has everything. Before I get to the bad, I did add Remus exhaust, and I changed out the radio because the stock radio was worse than my HD stock radio - by far. The bad - well it's not sure footed on the highway ONLY when you get in turbulent air from a semi, RV, or irregular load truck. I say not stable, but its not like you'll lose control or anything, its sorta like riding a street glide and fairing moving, but the bike moves here, just a little wobble, it will wake you up! Second, the aforementioned stereo out the box SUCKS. You can't hear it at 60! The BMW riders typically are a little pompous, and uptight.
I changed the speakers, and it was EXPENSIVE. A guy in Russia (yes, Russia) made some aftermarket pods that allowed me to replace the stock 4" speakers with 6.5's I added an amp, stereo problem solved. I changed the windshield, and it helps a little with buffeting but doesn't solve it. As for 18k service where they check the valves, I'll see when I get there. But for $23k with a 4yr/42k warranty, I should be safe from all the BS type stuff. The year I bought (18), it only came in black. I had it wrapped. With 160 hp/128 lb-ft torque this thing moves. Shifting a the 8500 redline will lift the front tire off the ground. My HD motor went to Dragos for the Diablo stage 2.5 kit, with Dragos 2into1, was dyno'd at 112/118, and couldn't keep up with bike if I let my wife ride the BMW. Riding the 3 sisters here in Texas on the BMW is funny, my group is mostly baggers, and we all ride together, but once the road curve, watching them fall back is something to see, they can't keep up with this thing.
So, to each his own, but the OP asked who owns both, and here are my thoughts. The BMW wins in my opinion hands down - so much, that I am currently selling my RG. It's collecting dust.
