【TALON TR339R/L Rear Sprocket, 520 Size, 51T, Magnesium, for YZ125/YZ250/YZ426/YZ450F/WR250R/WR250X/WR250/WR400F, WESTWOOD】
・Uses 7075 T6 aluminum, known for its lightness and excellent rigidity, and also used in aircraft.
・Designed and developed to reduce unsprung weight, thereby smoothing the operation of the rear shock and improving the overall balance of the machine. It also features self-cleaning grooved machining to reduce resistance caused by mud and gravel between the chain and sprocket.
・It is essential to replace the chain and sprockets simultaneously as a set of three! If the chain is stretched, simply replacing the sprocket alone with a new one will cause abnormal wear on the sprocket to match the stretched chain's link spacing. This not only prevents the sprocket from performing its original function, but also ultimately shortens its replacement cycle.
