Innovative tank bag attachment - Fidlock patented

The HEPCO&BECKER tank ring for fastening tank bags is a big advance for attaching tank bags to the motorcycle.
The problems associated with positioning the tank bag are eliminated by magnetic centering.

The side ribs attached to the magnets also mechanically secure the tank bag.
When the lock is released, the poles of the magnets match and the tank bag is released from the attachment.
The tank bag‘s base plate shields the magnetic field of the tank ring‘s two permanent magnets so that credit cards and electronic devices cannot be damaged. 

Facts:

special powder-coated metal tankring
two high power magnets secure the tank bag on the ring
every tankbag by HEPCO&BECKER can be fitted, but depends also on bike specific tank-lid positioning and handlebars; please check the manual for more info and limitations
Tankbag "Daypack small 640804" does not need tankring
