Rear Sprocket 420 Size 54T Gold for CR80/CR85/CRF150R/CRM50/CRM80

[TALON TR132R/L Rear Sprocket, 420 Size, 54T, Gold, CR80/CR85/CRF150R/CRM50/CRM80 WESTWOOD] ・Made of 7075 T6 aluminum, known for its lightweight and excellent rigidity, also used in aircraft. ・Designed and developed to lighten unsprung weight, thereby smoothing the action of the rear shock and improving the overall balance of the machine. It also features self-cleaning grooved (channeled) machining to reduce resistance caused by mud and gravel between the chain. ・It is standard practice to replace the chain and 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. This not only prevents the new sprocket from performing optimally but also shortens its replacement cycle. Compatible models/years: HONDA CR80/'85-'09, CR85/'85-'09, CRF150R/'85-'09, CRM50/'88-'97, CRM80/'88-'97 *While the CRF150R is originally 420 size, it can be converted to 428 size for improved strength/durability.
