Increase the capacity of your BMW aluminum pannier system by 12 liters per side with this clever "Volume Booster" kit from Touratech.  Compatible with the OEM BMW aluminum panniers on the BMW R1250GS/GSA, F850GS/GSA, F750GS, and R1200GS/A (liquid cooled), these pannier extensions are a quick, secure, and watertight way to expand your cargo carrying ability.

Built and designed by Touratech, the original equipment manufacturer for BMW aluminum panniers, you know these volume boosters will match the stock side cases perfectly and will be the same great quality. The pannier volume boosters are available in raw aluminum or black anodized finishes.

Simply place these aluminum lid spacers between the pannier box and the lid and latch down like normal.  The boxes still operate with a hinging lid and locking latch with your ignition key.  When you don't need the extra space, simply take them off.  There is no better way to securely expand your luggage system's capacity.

Available individually or as a pair, so you can decide to expand both panniers or just one.

To go along with your new Volume Booster check out these Booster Cubes made specifically for them.
