{"product_id":"tk-02-07-0144","title":"Drive Chain Gold \u0026 Black 420-120L KX80 ('96-'00), KX85 ('01-'02)","description":"By increasing the thickness of the link plates compared to standard products, the strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).\u003cbr\u003e\nFurthermore, it is the strongest drive chain in the 420 series, featuring SDH treatment and solid bushings.\u003cbr\u003e\nSDH Treatment\u003cbr\u003e\nThe cause of chain stretch is wear between the pins and bushes.\u003cbr\u003e\nWhen fine, hard, harmful particles such as sand and dust enter between the pins and bushes, it promotes chain wear, causing vibration and noise, and shortening the chain's lifespan.\u003cbr\u003e\nIn such cases, D.I.D.'s developed SDH treatment demonstrates its effectiveness.\u003cbr\u003e\nSDH treatment forms an extremely hard film on the surface of the pins, and this film has even higher hardness carbides dispersed within its structure.\u003cbr\u003e\nTherefore, even if hard foreign particles enter between the pins and bushes from the outside, it prevents chain wear.\u003cbr\u003e\nSolid Bushing\u003cbr\u003e\nThis is a roller chain with excellent wear resistance that uses highly rigid solid bushings with a seamless, smooth surface and excellent roundness.\u003cbr\u003e\nSolid 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 the bushing.\u003cbr\u003e\nChain Size: 420\u003cbr\u003e\nColor: Gold \u0026 Black\u003cbr\u003e\nNumber of Links: 120 links\u003cbr\u003e\n*The image is for illustrative purposes only, and the design and specifications of the products shown are subject to change without notice.
