The Easy Lock System for tank bags eliminates straps and magnetic attachments previously used to fasten tank bags to a motorcycle. Thanks to a small ring that is installed around the gas cap, incorporated with the unique structure of the base of the bag, the bag can now be attached by simply aligning it to the ring and pressing lightly until you hear a positive “click.” It is equally as easy to remove the bag. To release pull the red lever located in the base. The mounting rings vary by the fuel cap type. Please confirm compatibility below to verify which ring is for use with your model of motorcycle.
