The GIVI easy lock tank ring BF25 allows a GIVI easy lock XS320 tank bag to "float" above your Honda Africa Twin CRF1000L tank protecting its finish. This innovative system for GIVI tank bags removes the need for straps or magnetic attachments that could mar your tank. This small ring is installed on your gas cap and links up to the unique structure on the base of the bag. To mount the tank bag simply align the two and press until you hear a "click". To release the bag pull the red tab located on the bottom of the tank bag. The GIVI easy lock tank ring BF25 is compatible only with the GIVI XS320 XStream tanklock tank bag.
