Suitable for the model-specific  HEPCO & BECKER Lock it tank rings, this everyday little helper can be mounted on all models with a matching tank cap. 

The functional principle of the tank ring closure:

The problems when putting on tank bags are eliminated by magnetic centering. Handling is quick and easy. The system is mechanically secured by the ribs attached to the side of the magnets. The transmission forces of the bracket are over 70kg vertical load, so that a stable and secure connection to the motorcycle is guaranteed at all times. To unlock, a pull on the retaining strap is sufficient so that the magnets unlock the system. The magnets are aligned in the same way and the tank bag can be removed. 
Easy as pie and effective - simply ingenious. 

• Suitable for the Royster side bag product family and the Royster rear bag
• The tank bag does not sit directly on the tank, so that damage to the paintwork is avoided
• Can be mounted on Lock-it tank rings, or sports and mini racks with Lock-it fasteners. A Lock-it mounting kit is required for Sport and Miniracks. Item 506100
