[TALON TR339R/L Rear Sprocket, Sprocket 520 Size, 52T, Gold YZ125/YZ250/YZ426/YZ450F/WR250R/WR250X/WR250/WR400F WESTWOOD] ・Made from 7075 T6 aluminum, known for its light weight and rigidity, also used in aircraft. ・Designed and developed to reduce unsprung weight, thereby smoothing the action 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 the sprocket. ・It is standard practice 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 the new sprocket to wear unevenly to match the stretched chain's link spacing. This not only prevents the sprocket from performing optimally but also ultimately shortens its replacement cycle.
