[TALON TR339R/L Rear Sprocket, 520 size, 44T, Gold, for 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 improve the machine's overall balance by reducing unsprung weight, which allows the rear shock to operate more smoothly. 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, front sprocket, and rear sprocket all at the same time! If the chain is stretched, simply 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 will this prevent the new sprocket from performing optimally, but it will also prematurely shorten its replacement cycle.
