To install throw-over saddlebags to your bike, remove the passenger seat. You would then ensure that the hook and loop connectors are firmly pressed together and secure bonding the two bags. To ensure additional stability, use the strap at the top of one saddlebag and thread it through the double d-ring on the other saddlebag. Place the saddlebags on the top of your bike and adjust to how you want the bags to sit. After this is complete, re-install your passenger seat. There are additional straps on the bottom of the saddlebags for added security and stability as well.
