PBR Standard Steel Sprocket 4351 - 428: born from PBR's competition experience, this rear sprocket is designed for off-road and motocross practices where reliability and strength are essential. Suitable for 428 configurations, it offers a robust solution to replace a worn part or to prepare your machine for trail riding.
Manufactured according to strict processes, the PBR sprocket features good resistance to corrosion and abrasion while minimizing friction at the tooth profile. Its machining and alloy are designed to withstand severe motocross conditions: its uniform tooth profile aids in smooth torque transmission and controlled chain wear.
