Designed for off-road riders looking for a robust and easy-to-install transmission part, this JT Sprockets steel sprocket is intended for 520 fitments on motocross machines. Its standard 431 profile and 14 teeth allow for gearing adjustments to favor acceleration or range depending on your usage.

• Number of teeth: 14
• Chain pitch: 520
• Type: 431 — standard sprocket version
• Machining: CNC for precise tooth profile and good chain/sprocket contact

The SMC420 steel construction provides good mechanical strength against terrain stresses, while the CNC machining ensures a finish that facilitates chain movement. Ideal for original replacement or for modifying the gearing on your motocross bike.
