PBR Standard Steel Sprocket 333 - 520 (Manufacturer part number: 333 13 18NC) — sprocket designed for off-road machines, intended for motocross use and the demands of the terrain.
Derived from PBR's racing experience, this sprocket uses an 18NCD5 steel alloy known for its mechanical strength. Its design focuses on durability on muddy and abrasive surfaces: resistance to corrosion and abrasion, friction control at the tooth level, and a rigorous manufacturing process to ensure consistent geometry and controlled wear.
Designed for riders who prefer mechanical reliability and a robust transmission, this sprocket fits compatible 520 setups. Example application: HONDA CR 125 R (JE01) 1986 - 125 cm³. Always check full compatibility with your transmission before installation.
