PBR C-Light Steel C45 Ultra-Light Sprocket 4690 - 520

Designed for motocross riders seeking reliable and lightweight equipment, the PBR C-Light sprocket (ref. 4690 49 C45) combines quality materials with precision machining. Born from a collaboration with WMX champion Kiara Fontanesi, it incorporates proven technical solutions to provide strength and weight reduction without extravagance.

CNC machined from black galvanized C45 steel, this sprocket features a series of well-designed lightening holes that reduce rotating mass while maintaining a reinforced contact surface for the chain. Suitable for a 520 pitch, it has 49 teeth and installs like a robust standard component on off-road vehicles.
