PBR Standard Steel Sprocket 4729 - 428 (Manufacturer Ref: 4729 46 C45)
Designed for roadsters and small trails, this PBR sprocket combines competition materials with controlled industrial manufacturing. Its construction from 18NCD5 steel alloy ensures a robust part, treated to minimize wear both on the track and in urban use. Subtle black finish for a discreet racing look on your swingarm.
This sprocket fits transmissions equipped with a 428 chain and is suitable for setups requiring a standard 46-tooth part. PBR manufacturing relies on strict processes that control machining and heat treatments, offering better resistance to corrosion and abrasion compared to untreated steels.
Common compatibilities: BENELLI TORNADO NAKED T 125 (2025), KEEWAY RKF 125 (2023), BENELLI BN 125 (2025). Please check the pitch and number of teeth of your setup before ordering for precise fitting.
