Drive Chain Gold & Black 420-74L Z50J(12V)/AB27/Monkey Baja

By making the link plate thicker than the standard product, the strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).
Furthermore, this is the strongest 420 series drive chain, equipped with 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 or dust get between the pins and bushings, it accelerates 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 effectiveness.
SDH treatment forms a very hard film on the surface of the pin, and this film has even harder carbides dispersed within it.<
Therefore, it prevents chain wear even if hard foreign particles get between the pins and bushings from outside.
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 press-fitted into the link plate, forming an optimal contact bearing surface between the pin and bushing.
