While theoretically, a clean, well-lubed non-O-ring performs better in terms of transmission efficiency, in real-world conditions, it generally doesn’t, as dirt and muck stuck between the linkages causes friction, making it less efficient in practice. The rubber inserts that act as seals help the O-ring chains keep the external elements. The non-O-ring chains were notorious for trapping dust between the linkages, which, when ignored, resulted in the loss of power and efficiency. O-ring chains keep dust and debris away from the pin. Here are some advantages of O-ring chains over their non-O-ring counterparts: Though they are much more expensive, they are worth every penny due to the peace of mind they offer and the low amount of maintenance they require. O-rings are definitely superior to the non-O-ring chains in every way, except that the transmission loss on a well-cleaned and lubed O-ring chain is significantly less owing to the additional drag created by the rubber rings. The seals ensure that dust and debris are kept away from the inner parts of the chain. This helps avoid the metal-on-metal friction that the non-O-ring chains are plagued by. O-ring chains are self-lubricating and help seal the lubricant inside the links of the chain to keep the pins moving freely. When you look at its cross-section, it gets the name O-ring from its cylindrical shape. The O-ring chain solved all these issues by adding an O-ring rubber inserted between the inner and outer link plates to act as seals. They didn’t last too long either and had to be replaced frequently. This meant that the non-O-ring chains required regular maintenance in cleaning and lubing. It also tends to trap dirt and debris around the pin. The non-O-ring chains had an issue wherein there was a lot of metal-on-metal contact between the link plates, and the chain could not easily retain lubricant. O-ring chains were derived from the older and standard non-O-ring chains. Before we discuss the maintenance of O and X-ring chains, let’s first try and understand what makes them unique, and how these two varieties of motorcycle chains are different. While essentially maintenance-free, the O and X-ring chains need their share of care to keep serving you in a trouble-free manner. Motorcycle users often wonder whether they need to clean or lube these modern chains at all. Having said that, the exterior of these chains still has to weather the elements. While the older chains require a lot of maintenance and care in the form of constant cleaning and lubrication, modern O and X-ring chains come pre-lubricated on the inside and are sealed to stay well-oiled on the inside. Incredibly durable and is built to take abuse, motorcycle chains are some of the most stressed components on any two-wheeler. In fact, to watch this series of linkages in action, transferring monstrous amounts of power from the engine to the rear wheel, enabling the machine to achieve manic acceleration and top speeds, is a sight to behold. It is no secret that motorcycle chains are a vital part of a motorcycle’s drivetrain.
