[TALON TR339R/L Rear Sprocket 520 Size 46T Magnesium YZ125/YZ250/YZ426/YZ450F/WR250R/WR250X/WR250/WR400F WESTWOOD]
・Made from 7075 T6 aluminum, known for its lightweight and superior rigidity, also used in aircraft.
・Designed and developed to improve the machine's overall balance by reducing unsprung weight, which in turn smooths out the rear shock's operation. It also features self-cleaning grooved machining to reduce resistance caused by mud and gravel between the chain and sprocket.
・It is recommended to replace the chain and both sprockets simultaneously! If the chain is stretched, simply replacing only the sprocket with a new one will cause the new sprocket to wear unevenly to match the stretched chain's link spacing, not only preventing it from performing as intended but ultimately shortening the replacement cycle.
