Motorcycle Chain

In essence, there are two kinds of motorcycle chain: sealed chains and unsealed chains.

Unsealed chains, also referred to as “standard roller chains”, are simply a series of metal links that form plain bearings. You typically find unsealed chains on older models as well as off-road motorcycles.

Sealed chains, on the other hand, have rubber seals known as O-rings fitted in between the inner links and the side plates. O-rings seal in the grease and prevent dirt from corroding the links. Therefore, O-ring (sealed) chains have much greater longevity than standard (unsealed) chains.

By massively reducing the amount of lubrication needed, sealed chains revolutionised the industry and became the dominant chain type for motorcycles. Riders prefer them for their inexpensive cost, superior efficiency, and lack of comparative maintenance. Recent years have seen new forms of sealed chains being developed – most notably the X-ring. First conceived for track racing, the X-ring’s smaller surface area reduces friction when riding, making it the perfect choice for rider’s seeking maximum efficiency.
