Swift Chain Standard
Swift Chain's standard chain offers exceptional value compared to other chains on the market. Manufactured with exacting standards in Taiwan, Swift Chain is resistant to corrosion and rust, and uses specially heat-treated steel for strength and durability. In many cases Swift Chain has equal or higher ultimate tensile strength than the equivilent chain from leading manufacturers.
|Pin Length||Roller Diameter||Plate Thickness||Weight||Tensile Strength|
|14.80mm||7.77mm||1.5mm||0.73kg per 100 links||19.61KN|
If the original equipment chain was an O-Ring or X-Ring chain it must not be replaced with a non-O-Ring or non-X-Ring chain. It must be replaced with a sealed chain of equal or greater strength.
Delivery and Returns

A motorcycle chain comprises two precision ground pins peened at each end as a rivet, two bushes, two rollers and two side plates. A further pair of outer side plates join each link to the next link. In O ring chain a round seal is fitted on the pin between the plates to retain lubricant. The seal is contoured for less drag in X ring chains.
The Number of links is measured by the number of pitches, which is the gap between each pin or rivet and includes a Spring/clip or Rivet link to give an even number.
Please note that we supply lengths of chain to fit standard sprockets. When using sprockets with 2 or more extra teeth a chain with more links is often needed. Feel free to call for any assistance.
Side plate thickness varies with grade and make of chain. As a rule, 1.5 to 2.6 mm. It is important for safety to join chain with the manufacturers correct Rivet Soft Link or Split Spring Link.
Size, Manufacturer, and grade are often stamped on some of the side plates.
Replacing The Drive Chain
The chain will naturally stretch as it wears. On a non-sealed chain this should not exceed 3% of its original length. Sealed chain stretch should not exceed 1% of its original length. If the stretch exceeds this it needs to be replaced.
A drive chain that carries too much tensions speeds up wear by excessive amounts of pressure being placed on the sprocket teeth, chain joints and the gearbox main-shaft bearings. One that is too loose is at risk of a whip action that may cause it to snap. Having an incorrect tension can also cause the chain to stretch.
Normal sag is 3/4"; to check, press down on the top strand of the drive chain with your fingers. Tighten or loosen to achieve the desired sag. Note this should be performed with the weight of the rider on the bike. It is advised to check your manufacturer's handbook for your particular machine.
Misaligned sprockets can greatly reduce chain and sprocket life. Check sprocket alignment periodically to ensure they are straight.
