Rear Sprocket, 520 size, 43T, Magnesium - CR125/CR250/CRF250R/CRF450R/XR250

[TALON TR113R/L Rear Sprocket, 520 Size, 43T, Magnesium, CR125/CR250/CRF250R/CRF450R/XR250 WESTWOOD] ・Made from 7075 T6 aluminum, known for its lightweight and superior rigidity, also used in aircraft. ・Designed and developed to lighten unsprung weight, smoothing the operation 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 and sprocket. ・It is recommended to replace the chain and sprockets together as a set of three! If the chain is stretched, simply replacing the sprocket alone will cause the new sprocket to wear abnormally to match the stretched chain pitch, not only preventing it from performing as intended but also ultimately shortening its replacement cycle.
