Givi's TankLock system eliminates the use of straps or magnets for mounting your tank bag - you simply install the bike-specific ring on the tank cap, and then attach the bag by alligning it to the ring and pressing lightly until you hear the "click." Equally easy is the removal of the bag, you just pull the red lever located in the base.
Check Givi's MY MOTORCYCLE listings to verify the compatibility of the "BF" flange for your motorcycle.
