Description
Overview:
This chain drive sprocket is a Genuine Stihl part designed for selected Stihl cordless chainsaws, including the MSA 120 C and MSA 160 T. It is a precision-machined, 7-tooth sprocket for 1/4 inch pitch chain (6.35 mm) that transfers motor power to the chain reliably and smoothly. Made from hardened steel with a durable, silver finish, it is built to resist wear and maintain consistent cutting performance over time. The OEM reference 1252 642 1201 helps ensure correct identification and a proper fit on compatible machines. Replacing a worn sprocket restores efficient power transfer, helps protect the guide bar and chain, and keeps your saw cutting cleanly. Suitable for professional users, grounds teams, and home gardeners maintaining smaller timber and pruning work.
