Harley-Davidson X440 / X440 OBDII Rear Sprocket / Final Driven Sprocket OEM | HDH41201RAA000

Replace a worn or damaged rear sprocket with this genuine OEM rear sprocket for Harley-Davidson X440 series motorcycles. Part number HDH41201-RAA-000 is listed in the genuine parts record as SPROCKET FINAL DRIVEN 39T. In buyer language, this is best understood as the rear sprocket, also commonly called the back sprocket or final driven sprocket.

This is the sprocket mounted at the rear wheel that works with the drive chain and front sprocket. If the old rear sprocket is worn, hooked, noisy, causing uneven chain wear, or being replaced as part of a chain-sprocket service, this is the correct OEM-style replacement for the listed applications.

This listing is written to be easier for customers to understand. Instead of only using the factory term SPROCKET FINAL DRIVEN 39T, it also uses the common buyer names: rear sprocket, back sprocket, and final driven sprocket.
