Description
If you’re running a YZ85, sprocket wear directly impacts acceleration, chain life, and overall drivetrain efficiency. The Renthal 48T Blue Rear Sprocket delivers the lightweight performance advantage you need—a 7075-T6 aluminum construction that cuts weight by approximately 66% compared to steel while maintaining the rigidity required for consistent power transfer. Self-cleaning mud grooves at each tooth prevent debris buildup, ensuring your sprocket performs reliably lap after lap, whether you’re training or racing.
