How to Choose Between 520 and 520H Motorcycle Chain
Both 520 and 520H follow ANSI standards and share the same 15.875mm pitch. The core difference lies in structure and load capacity. The standard 520 features regular plate thickness and ultimate tensile strength of 26.5 kN. It is cost-effective, lightweight and perfectly suited for 150cc-200cc motorcycles for daily commuting and casual street riding.
520H is the heavy-duty upgraded version. With thicker side plates and reinforced pins, its tensile strength reaches 30.0 kN, delivering superior sturdiness and impact resistance. This model is the top pick for 200cc-250cc bikes, aggressive riding, off-road travel and high-torque working conditions. We also offer O-ring sealed variants and full sets of attachments for both models to meet diverse installation and application needs.
