Drive Chain Gold & Black 420-78L (NZ3) XR50R/Giorno Cub

By making the link plate thicker than standard products, the strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).
Furthermore, it is the strongest drive chain in the 420 series, featuring SDH treatment and solid bushings.
SDH Treatment
The cause of chain stretch is wear between the pins and bushings.
When fine, hard, harmful particles such as sand and dust enter between the pins and bushings, they accelerate chain wear, causing vibration and noise, and shortening the chain's lifespan.
In such cases, the SDH treatment developed by D.I.D. demonstrates its power.
SDH treatment forms an extremely hard film on the surface of the pins, and this film further disperses high-hardness carbides internally.
Therefore, even if hard foreign particles enter between the pins and bushings from the outside, chain wear is prevented.
Solid Bushing
This is a roller chain with excellent wear resistance that adopts a highly rigid solid bushing with a seamless, smooth surface and excellent roundness.
Solid bushings reduce the barrel-shaped deformation of the bushing that occurs when it is pressed into the link plate, forming an optimal contact bearing surface between the pin and bushing.
