BMW S1000RR owners- The FastPack size 5 WILL FIT your bike! However because the seat release key is mounted on top of the seat, it will be necessary for you to cut a small slit in the bottom of the FastPack bag so you can get to the keyhole. We recommend taping a small fabric flap over the slit to prevent loose change from slipping through. This will not affect the integrity of your FastPack. Installing a FastPack size 5 on your BMW S1000RR will definitely increase the utility of the bike, letting you carry a water bottle, your lunch, etc.
