Reduce rotating mass and sharpen your bike’s response with the Renthal Ultralight Rear Sprocket. Precision CNC machining (not stamping) and an ultra-light design help cut unsprung weight, so your drivetrain can accelerate more freely and transfer power more efficiently. It’s made from high-strength, specially enhanced 7075-T6 aluminum—built to stay strong while delivering a noticeable weight advantage.
The sprocket’s special tooth profile is designed to let the chain roll on and off smoothly, which helps reduce noise and improves wear characteristics. The result is a more efficient, quieter final drive that stays consistent during hard motocross and enduro use.
Key features:
✅ CNC-machined ultralight design to reduce unsprung weight and increase power transfer
✅ Enhanced 7075-T6 aluminum construction for high strength with low weight
✅ Optimized tooth profile for smoother chain movement, longer wear and less noise
Benefits of use:
🔹 Lighter rear sprocket helps your bike feel more responsive under acceleration
🔹 Improved chain engagement for smoother, quieter drivetrain operation
