[TALON TR339R/L Rear Sprocket, 520 size, 44T, Blue, for YZ125/YZ250/YZ426/YZ450F/WR250R/WR250X/WR250/WR400F, WESTWOOD] ・Made of 7075 T6 aluminum, known for its use in aircraft, offering excellent lightness and rigidity. ・Designed and developed to reduce unsprung weight, thereby smoothing the action of the rear shock and improving the machine's overall balance. It also features self-cleaning grooved machining to reduce resistance caused by mud and gravel between the chain. ・It is recommended to replace the chain and sprockets simultaneously! If the chain is stretched, 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 failing to deliver its original performance but also ultimately shortening the replacement cycle.
