Replacing a worn rear sprocket together with a new drive chain and gearbox sprocket restores smooth, efficient power delivery through the final drive and extends overall drivetrain life. A worn rear sprocket accelerates chain wear and reduces drive efficiency — this is the correct OE-specification replacement to bring your Commando back to factory standard.
