There are three ways to attach the saddlebags to a motorcycle.First is to make the saddlebags Bolt On and to use the quick release Quick Mounts.  Second, is the old school throw over saddlebags.  These bags are connected with a yoke which goes under the seat. We recommend the saddlebag support brackets to keep the bags out of tires and calipers and to keep the bags from flapping around like Dumbo ears. Saddlebag support brackets can be purchased online or through a dealer. Our throw over saddlebags are zipper detachable, so you can take the saddlebags off and take them with you.  The yoke stays on the motorcycle. Our economy line have the yokes sewn to the bag and tie under the seat.Third is to permanently mount the saddlebags to the side of the motorcycle.  We recommend the saddlebag support brackets described above. With the support brackets installed then drill through the back of the bags and mount them to the side of the bike using the same holes the saddlebag support brackets are using. This is a custom application and you need to contact us to order the bags this way.
