DRIVEN RACING Rear Sprocket - 47-Tooth 5178-520-47T

If you're chasing lap times or building a race-ready drivetrain, sprocket weight directly impacts acceleration and throttle response. The DRIVEN RACING 47-tooth rear sprocket combines lightweight construction with proven durability—you get the performance advantage of reduced rotational mass without sacrificing chain longevity. Whether you're on the track or the street, this is the sprocket engineered to deliver.

Built using proprietary EST Technology and featuring a lowered tooth surface that strips away unnecessary material, this 520-pitch sprocket is among the lightest options available. The black zinc semi-gloss finish resists corrosion while maintaining that purposeful, track-ready appearance.
