MF Catenificio Frigerio Anti-theft chains are ideal for the protection of motorcycles and are built with features that make them particularly resistant to the action of cutting tools. They can be made of square or hexagonal links, using boron-treated and hardened C23 steel, to ensure best possible resistance. They are covered with a stylish black polypropylene cover, with an embroidered logo, to protect the metal parts of the motorcycle against scratching. Round link or half-round link models are also available made of hardened steel and heat-shrank tubing.
