For the BMW Adventure bikes (and the S1000XR) you have 2 options depending on your riding style and preference:
For a large, full coverage hand cover that is suitable for true winter riding and to completely protect your hands, even in heavy rain conditions, choose the Alcan model. Click the image below to choose your options
For riders who want a smaller hand cover, that still offers very good protection but also is better suited for standing while riding choose the Back Country model.
