What are O Ring and X Ring chains?
There are three principal types of roller drive chains: O Ring less, O Ring and X Ring. The O Ring less types date back to the beginning of time and are still used a lot today. They are strong, light, cheap to produce and relatively friction free but they do not have internal lubrication, so they tend to wear out more quickly.
Chain design has had to improve with the technology of the motorcycle. With today’s bigger and more powerful bikes, normal O Ring less chains have lost out ‘O Ring’ and ‘X Ring’ chains. These two types of chains position a sealing ring between the inner and outer chain plates. Before riveting in the factory, the internal parts of the chain are filled with chain grease by vacuum. The sealing rings keep the internal lubrication in, and the dirt out, thus preserving the durability of the chain. O rings are literally ‘O’ shaped. As the two plates push on either side of the O ring, it distorts to have two flat sides to its shape. This is great on sealing and but creates a lot of friction which saps the bike’s power.
To reduce this friction ‘X Ring’ chains were developed. ‘X’ describes the shape of the ring. Instead of having an O shape it now has an X shape. This means that when pressed between the chain plates, it has two smaller faces touching either plate in an X shape. This gives you the same great sealing and durability but now with very low friction. The perfect chain-for now!

Great source of information.
Do you have any information on Ariel’s, particularly Sq 4 Mk 2 1959? tappets, ignition timing etc
It is really helpful. Especially for an beginner like us. I have two B33 and lot’s of parts passed onto me by my father. I do not know where to begin, and this has helped me a lot.
great stuff! Thanks!
thanks for the best Norton info I could ever hoped to find
How to I get a brand new or reconditioned MO1L magneto and E3L dynamo for mu 1956 model Royal Enfield in India.I have people in UK who are temporarily put up there .Pls help
Try http://www.hitchcocksmotorcycles.com/home in the UK. Cheers.
Very helpful to find exploded diagrams – especially when you’ve bought a box of bits and 3 different gearbox parts are mixed together!!
Finally, a good use for the internet!
