Original BMW pannier mounts with power connections and waterproof caps. Removed these from my 2025 1300 GS as I use an aftermarket system. The female cables are not shown in the picture but hidden inside the casing.

Mounting straightforward but you may need the matching male power cord from the bike for the power to work - unsure if these cables are standard on all bikes or are additional items fitting by dealer when you purchase. It should re-use existing bolts to mount to the chassis otherwise you may need to source these but are regular torx bolts.

** these are not the AliExpress copies but BMW genuine parts and has the rough painted texture to match the rest of the bike and durability.
