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.

Adapter plate.

The product was easy to install and came with all the nesssary mountings. It appears to be of good quality and I look forward to field testing it off road.


The adaptor works great at providing a flat surface to mount the bag hangers on to the frame on the exhaust side.

Another top notch product from Mosko Moto

I have an Adventure Motorcycle touring company in Idaho and have tested many products of the years. Mosko Moto makes the very best stuff money can buy. The adaptor plate for the stock BMW pannier racks is no different. Works flawlessly and I know that my gear is going to stay in place and be there when I get to the next camping spot. Thanks Mosko Moto for putting all of you knowledge into your product offerings!

Strong, Effective and Well Designed

I purchased the 35L panniers for my GSA which required the adapter plate. Easy install and it has performed well over an entire season. It even fit (barely) over my Touratech tool carrier box.


As advertised. Very durable and made from high quality materials. Easy to install. I would highly recommend.
