Replace your sprocket with a component designed for both the road and demanding terrains: the JT Sprockets standard steel sprocket 1554 - 520 is a robust transmission part, suitable for quads, motocross bikes, and roadsters. Designed for heavy use, it easily integrates during a gear ratio change to restore controlled engine response.
CNC machining and high-strength steel alloy limit wear on the teeth and ensure precise geometry for smooth chain engagement. By adjusting the number of teeth, you can modify the gear ratio to favor low-end torque or extend top speed depending on your setup and riding style. Compatible with 520 transmissions, this sprocket can be mounted in conjunction with suitable sprockets and chains.
Examples of common fitments: HYOSUNG GT 250 R (2013), YAMAHA TT‑R 230 (2006), HYOSUNG GT 250 COMET (2013).
