Designed specifically for the R1200GS and Adventure (both oil and liquid cooled), the Sandstorm 4A is the pinnacle of Enduristan design – expandable, waterproof, and solidly mounted, this very well may be the last tank bag you buy!

With Enduristan’s Expandable Volume Technology, the tankbag’s volume is continuously adjustable between 13 and 20 liters. To expand the tank bag, simply release the two velcro straps and pull the outer part upwards. To reduce the volume, simply pull the straps until the required volume is reached – a simple and very comfortable solution. The side walls are stiffened and a waterproof membrane between the sliding parts avoids the intrusion of water and dust.
