I had BMW Tourotech on DL650A and they fitted perfectly. Sorry, I can't tell you which model BMW they came off. They are a grey bluish colour with Tourotech written in black. Very useful they were too. I carried a first aid kit in one and my lock in the other. I had Suzuki OEM crash bars, others may be different.
I bought a pair of bags off AliExpress for my DL1000 2014. They were very cheap and I did see what looked like exactly the same things on eBay for a lot more money. Mine are really well made, quality and dry bags.
