900945 Rear sprocket, zinc. 48t

This zinc-plated 48-tooth rear sprocket is a solid choice for 1982 to 1985 FXR 5-speed models. With a 50mm inner diameter and a 12mm offset, it is built to the original specifications but offers a 48-tooth count for those looking to fine-tune their gearing. The 12mm offset is a well-known secret among custom builders, as it offers 6mm more clearance than the common FL or FX sprockets, allowing for slightly wider rear tires on 4-speed custom builds. This MCS part, number 900945, provides a rugged finish and precise fitment for both stock FXR maintenance and custom drivetrain projects. It is a dependable sprocket that balances durability with the technical requirements of vintage and custom Harleys.
