PBR Standard Steel Sprocket 4412 - 420 (4412 62 F): a sprocket designed for urban use where reliability and longevity matter. Born from PBR's experience in competition, it caters to riders looking for a robust transmission part to drive the rear wheel without compromise.
The PBR sprocket is designed according to a strict manufacturing process, with treatments aimed at improving resistance to corrosion and abrasion while minimizing friction at the tooth level. Its 18NCD5 steel provides mechanical strength suitable for the demands of the transmission, reducing wear and maintaining good torque transfer to the wheel.
Before installation, check compatibility with your pinion and chain length (pitch 420). Particularly suitable for urban use and the 50 cc models listed below:
An essential spare part for maintaining the transmission: simple replacement during chain/pinion maintenance, to be entrusted to a professional if necessary.
