Rear Sprocket 420 Size 51T Magnesium CR80/CR85/CRF150R/CRM50/CRM80

【TALON TR132R/L Rear Sprocket, 420 Size, 51T, Magnesium, CR80/CR85/CRF150R/CRM50/CRM80, WESTWOOD】
・Made of 7075 T6 aluminum, known for its lightweight and rigid properties, also used in aircraft.
・Designed and developed to reduce unsprung weight, thereby 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 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 links, which not only prevents it from performing as intended but also shortens its lifespan. Compatible models/years: HONDA CR80 / '85-'09, CR85 / '85-'09, CRF150R / '85-'09, CRM50 / '88-'97, CRM80 / '88-'97
