On my 2018 Dl 1000a the SW Motech bars broke at the center crosspiece joint.
They were on less than 3k miles. They were by all appearances , sturdy , well fitting, and well designed .
One day I noticed some unusual vibrations, when shifting mostly, and I thought it logically must have something to do with the bars.
I checked the torque on the main mounting bolt, tightening it slightly , and thought I would see if it made any difference. The next time I rode it, it was still having a subtle vibration, but riding conditions were too nice to go back to the garage and play with bar mounts.
Before very long I thought I had picked up some gravel in my front fender from the loud noise up front. An examination revealed the bar had snapped as shown.
