[TALON TR339R/L Rear Sprocket, 520 size, 46T, Gold for YZ125/YZ250/YZ426/YZ450F/WR250R/WR250X/WR250/WR400F WESTWOOD] ・Made from 7075 T6 aluminum, known for its light weight and superior rigidity, also used in aircraft. ・Designed and developed to reduce unsprung weight, thereby smoothing rear shock operation and improving the machine's overall balance. It also features self-cleaning grooves to reduce resistance caused by mud and gravel between the chain and sprocket. ・It is fundamental to replace the chain and sprockets simultaneously as a set of three! If the chain is stretched, replacing only the sprocket will cause the new sprocket to wear unevenly to match the stretched chain pitch. Not only will this prevent the original performance from being achieved, but it will also prematurely shorten the replacement cycle.
