An O-krou\u017ekov\u00fd motocyklov\u00fd \u0159et\u011bz<\/strong> is a type of drive chain that incorporates rubber O-rings between the inner and outer link plates at every pin-bushing joint. When the chain is assembled, these O-rings are compressed slightly against the plate faces, forming a seal that retains factory-applied grease inside the joint and prevents dirt, water, and abrasive particles from entering. Unlike non-sealed chains, which depend entirely on externally applied lubricant to protect the pin-bushing contact surfaces, an O-ring chain carries its own internal lubrication from the moment of assembly \u2014 and that lubrication remains in place for the chain’s entire service life regardless of what the chain passes through during operation.<\/p>\n

O-ring motorcycle chains offer a number of concrete advantages over non-sealed standard chains. The benefits stem directly from the sealing mechanism \u2014 once the internal grease is protected from the riding environment, a chain’s service life is determined primarily by the wear rate of the sealed components rather than the much faster rate of unlubricated metal-on-metal contact.<\/p>\n
