PBR Ultra-Light C45 Steel Sprocket 4691 - 520
Designed for the motocross world, the PBR 4691 sprocket combines durable C45 steel and precision CNC machining for a reliable drive component. Developed in collaboration with WMX champion Kiara Fontanesi, it aims to balance strength and weight reduction through a series of thoughtfully designed lightening holes. Its black galvanized treatment protects the surface against corrosion without unnecessarily adding weight to the transmission.
Ideal as a replacement for motocross/enduro machines, this sprocket is suitable for 520 transmissions and is aimed at riders looking for a lightweight sprocket without sacrificing wear resistance and torque. Please check compatibility with your model before installation. Application examples: HONDA CRF 450 X (2024), CRF 450 RX Enduro (2024), and CRF 450 R (2024).
