BMW R1200GSA / R1250GSA / F850GSA - Water Cooled Adapter

This BMW R1200GSA Water Cooled adapter provides a flat surface for mounting the Mosko Moto wedge that comes with the Backcountry Panniers. This adapter provides a flat surface for the Mosko mounting wedge on the OEM Touratech-made BMW BMW R1200GSA Water Cooled racks. Please review the picture below and visually confirm that this is the correct rack before ordering. This does not work with the OEM "Vario" style cases.

Note that this adapter set is meant to be purchased along with Mosko Moto Backcountry Panniers. In order to mount this adapter on the bike, the BMW R1200GSA Water Cooled adapter requires the Puck Sak mounting hardware that is included with our Backcountry Pannier kits, and is not included in this order.

This order includes one adapter and one elongated bracket to attach to your rack. You still require the Puck Sak, which includes 6 more pucks (brackets) that you will need to mount the adapter, which is included in the purchase of the Backcountry Pannier kit

Again, this adapter comes with all hardware needed as long as you have our Backcountry panniers (or Scout Panniers) or are ordering them today. If you are not using our bags then you will need some of our brackets (we call them pucks), so please contact us directly about this.

This adapter is designed to make Mosko Moto bags work on these racks, but they are also universal adapters for adding Rotopax or any other storage solution you may dream up.  

They are made of 3mm laser cut and bent T304 stainless steel, and powder coated black.

BMW R1200GSA / R1250GSA / F850GSA - Water Cooled Adapter

Excellent products as always!

Finally decided it was time to move away from the heavy metal Bmw GSA hard cases and convert my new 850 GSA to the MM panniers that I've been using on my 701. The MM GSA mounting plate worked great and now I can use my favorite panniers,(MM 35L Backcountry), on both bikes! 👍


My four star review is not because of the quality of the bags and hardware. They are simply top notch and I am very happy with them. My only product specific complaint is the velcro tie downs on the straps are too short, especially when you roll the ends of the straps up completely. The velcro barely holds on and has come loose going down the road. Yes, I could roll them up half way but that's just more stuff to flop in the wind or catch on some tree branch. My main issues are two things, although not major. The packing job literally consisted of throwing all of the items in a large box with no packing material to keep the items from moving all over the place. The tape used to seal the box was barely secured causing the box to be partially open when I received it. Just glad nothing fell out. I would expect more after spending almost $1000 on this system. And why not throw in some stickers or a hat. The other issue is with the installation instructions on YouTube. I have a 2018 GSA so I needed the adaptor plate for the OEM bracket on the exhaust side. This was really not covered in the video other than watching it being hung on the OEM rack. I had to take the OEM reflector brackets off the racks (don't care about them anyway) which helped me to straddle the longer clamps (one for each side) over the rack tabs which are used to mount the OEM panniers, I eventually figured it all out with two short clamps left over. Would have helped if the video was more detailed about this specific application as there are many of us in the same situation. Otherwise, I look forward to getting a lot of off road use out of these bags for years to come.

GSA1200 adapter

Purchased it along the 35 Liters BC. The adapter came with Puck Sak which are long. Found the Puck Sak which came with the BC 35 more useful.


Really appreciate the gear and how easy it was to install, I have just done local rides, but will test it next week. Big reason for the purchase was your staff at AZ Overland, they sure explained everything in detail and really nice, even when they knew I was not ready to purchase at that time. Thanks.
