The system of strength and reliability, characterised by one special inner long link and with an end round ring. It allows anchorages to fixed supports with a double loop, taking advantage of the length of the chain without forcing the motorcyclist to put the bike very close to a post. It also allows fixing together 2 bikes in the minimum space.
It gives the maximum security for motorbikes with medium and high power engines or when leaving a high value bike in a risky place for a long period.
