Hello, I own a 2020 R1250 GSA. It is equipped with the black BMW branded panniers made by touratech. While stopped bike was struck from behind on the right pannier. The only damage besides some rash on a corner is the mounting lock clamp is bent. The lock still functions but because of the bent lock clamp the bag is loose. My dealership says the lock is not offered. Touratech USA told the dealership the lock is unavailable. E-mail to Touratech Germany is unanswered. Solutions?
