JT Sprockets Standard Steel Sprocket 423 - 530 (Manufacturer Part No: JTF423.18)

Designed to replace your original sprocket or modify the gearing, this JT Sprockets sprocket is aimed at riders who demand reliability in their transmission. Suitable for both Cross and Roadster applications, it fits on compatible 423 shafts and accepts a 530 pitch chain. Ideal for maintenance interventions or to adjust engine behavior according to your usage.

• Material: steel (SMC420 alloy) providing good wear resistance
• Number of teeth: 18 (sprocket)
• Chain pitch: 530
• Type: 423 — standard version
• CNC machining for precise tooth profile and controlled geometry
• Lightweight and optimized design to limit unsprung masses

This sprocket retains the original dimensions and easily integrates into compatible transmissions. A relevant reference for a wide range of machines — from the KX125 to large roadsters like the Hayabusa or GSX-R 1000 — it allows for a clean tooth profile and a reliable interface with the sprocket and chain. Please check the exact compatibility with your motorcycle before ordering (type 423 / pitch 530 / 18 teeth).
