Ideal for the maintenance or refurbishment of your primary transmission, this sprocket meets original tolerances to ensure proper engagement with the 428 chain and sprocket. Mounted on lightweight machines (125 cm3), it is particularly suitable for YAMAHA R125 (2025), BETA RR 125 4T ENDURO LC (2021), and RIEJU TANGO 125I SCRAMBLER (2020).

Before installation, check compatibility with your model and the condition of the sprocket and chain. Replacing a worn sprocket helps limit premature wear of the entire chain/sprocket system and restores consistent transmission behavior.
