Reduce weight where it matters most. The Renthal Ultralight Rear Sprocket is designed to cut unsprung weight and help your bike accelerate and respond more efficiently. Its CNC-machined (not stamped) construction delivers precise tolerances and an ultra-light design that supports stronger, more consistent power transfer.
Made from specially enhanced 7075-T6 aluminum, this rear sprocket is about 33% lighter than steel while maintaining excellent strength for demanding motocross and enduro use. A special tooth profile helps the chain roll on and off smoothly for longer wear, less noise and efficient drivetrain performance.
Key features:
✅ CNC-machined ultralight design to reduce unsprung weight and improve power transfer
