[TALON TR339R/L Rear Sprocket, Sprocket, 520 Size, 48T, Gold for YZ125/YZ250/YZ426/YZ450F/WR250R/WR250X/WR250/WR400F, WESTWOOD] ・Made of 7075 T6 aluminum, known for its use in aircraft, offering lightweight and superior rigidity. ・Designed and developed to reduce unsprung weight, 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 the sprocket. ・It is recommended to replace the chain and both sprockets simultaneously! If the chain is stretched, replacing only the sprocket with a new one will cause the new sprocket to wear out prematurely due to the stretched chain's link spacing, not only preventing it from performing as intended but also shortening the replacement cycle.
