DID NZ 428 Super Heavy Duty Chain

DID NZ Super Heavy Duty Non-O-ring chains are designed with Motocross in mind. The amount of sediment that a motocross chain must endure makes o-rings impractical, as dirt can be trapped beneath them. Yet a hard-wearing, long-lasting chain is a must for the sport.
Featuring quad-riveted, SDH-treated pins, which forms a hard chromium-carbide layer on the pin's surface while maintaining a soft inner core, the pins of the DID NZ chain have extremely high impact strength while still maintaining shock absorption. This gives it superior wear resistance, at roughly four times that of a standard DID or regular heavy duty chain, as well as higher tensile strength.. DID NZ also has anti-oxidation properties and performs well against invasion of foreign materials, making it ideal for muddy or sandy conditions.

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.

Tension Adjustment

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.

Sprocket alignment

Misaligned sprockets can greatly reduce chain and sprocket life. Check sprocket alignment periodically to ensure they are straight.
