This specialized drivetrain component is the ultimate problem-solver for custom builds and frame stretches where a standard link removal makes the chain too short, but a full link makes it too loose. Engineered for high-stress applications, this link allows you to adjust your wheelbase by a half-pitch (approx. 6.35mm), ensuring smooth power delivery and reduced wear on your sprockets.\u003c\/p\u003e\u003ch3\u003eTechnical Performance Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Tensile Strength:\u003c\/strong\u003e Boasts an ultimate tensile strength of 20.60 kN (4,682 lbs), making it fully compatible with \"H\" (Heavy Duty) series chains used on performance mini-bikes and small motorcycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision 428H Geometry:\u003c\/strong\u003e Features a standard 12.70mm pitch and 8.51mm roller diameter, ensuring a seamless interface with any 428-series drive system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Plate Thickness:\u003c\/strong\u003e At 2.03mm thick, these plates match the durability of your primary drive chain, preventing the \"stretching\" common with inferior, non-H-rated links.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Drivetrain Compatibility:\u003c\/strong\u003e The go-to solution for Pocket Bikes, ATVs, Dirt Bikes, and custom motorized bicycles requiring a 428-pitch setup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003eComprehensive Fitment Guide\u003c\/h3\u003e\u003cp\u003eThis offset link is compatible with any \u003cstrong\u003e#428 or #428H\u003c\/strong\u003e roller chain.
