BETA sprockets for motocross, enduro and trials

BETA sprockets for motocross, enduro and trials

BETA sprockets for motocross, enduro and trials: more than 10 parts.

These parts are listed for 15 BETA models; the most common are BETA JONATHAN 350 (2001-2006), BETA RR 125 (2018-2023), BETA RR 200 (2019-2023), BETA RR 250 (2006-2023), BETA RR 300 (2013-2023) and BETA RR 350 (2011-2023).

Chain, rear sprocket and front sprocket wear together: a stretched chain wears the teeth, and hooked teeth soon wear out a new chain. Replace the whole kit, check the pitch (420, 428 or 520 depending on engine size) and tooth count, and set the tension as per the manual.
