I have a good riding buddy with a 1600. In the first 2 months the reverse went out, but BMW fixed that and doubled his warranty (No Japanese co would do that) and now at 22,000 miles it has been recalled (transmission I believe). None the less, it's his dream bike and he loves it.
We were out in Colorado riding passes and canyons on our CB 1100's and were eating dinner at a small steak house when a guy on a 1600 pulled in with full Akrapovics. By buddy looked at it and listened to it and said "I'm going to get one of those", and he did, Akrapovics and all. Dreams can come true lol. Plus he found 2 guys in his town that are hard core BMW riders he has hooked up with.They rode out to Alberta last summer and he had a blast. He's totally hooked in the BMW lifestyle now. He would have never considered a BMW flat twin.
I know I’ve posted my experiences before, but I will again. I had a 2013 and a 2015 1600. I kept them both three years and a combined 60,000 miles. I did have a few of the well known problems, but nothing that kept me off the road.
They were very nice bikes, and I would tell anyone that if the bike trips your trigger, buy it. I ultimately went back to the FJR as my long distance bike for four basic reasons.
1). $10,000 cheaper. I’m retired now. Money matters
2). The 1600 is a much roomier two up bike. But my wife never rides with me any more.
3). Im more confident keeping the FJR much longer and I’m able to get the YES warranty for about $400. I can rack up a lot of miles feeling better about the reliability, and even if I have to sell the FJR for practically nothing five years from now my overal cost of ownership will be far less than the 1600
4) The FJR handles the twisties better. The 1600 would keep up with it, but the FJR simply feels subjectively better pushing through curves.
