Givi TankLock BF10 Adaptor (Bag not included). With the new TankLock system for tank bags the straps and magnets that have been used to date for attaching them to the bike are no longer necessary. Thanks to a small metal ring that is installed on the tank cap and to the base with a hook specific to these bags, the fastening to the bike is carried out by pressing slightly. To unfasten you just need to pull a red lever situated on the base. The metal rings to install on the tank vary according to the type of cap, requiring verification that there is a ring specific for each model, make, cubic capacity and year of the bike.
