ČZ chains for demanding sports such as motocross are characterized by high resistance in dusty and muddy traffic. The ČZ company uses its own CRK technology for these chains, which consists in applying very hard chromium carbides to the surface of the pins. The hardness of these carbides is up to twice as high as that which can be achieved with hardened steel. The pins are refined by heat treatment to high strength in order to resist wear and tensile shocks during operation. The presence of chromium also guarantees resistance to corrosion of the pin surface.
tradition of manufacturing motorcycle chains since 1933 complete production of chains and all their parts only in Strakonice in the Czech Republic quality verified by deliveries to the assembly lines of world motorcycle companies
1) State-of-the-art technology and machinery including trained employees. Production operations are performed by automatic machines with minimal human intervention. Control systems implemented in technological processes to exclude production errors and incorporated into the requirements of ISO/TS standards.2) It goes without saying that we only use quality and tested materials from European suppliers.3) Development of chains with own test rooms and laboratories supported by cooperation with world racing motorcycle teams
