PBR Standard Steel Sprocket 4406 - 420
Born from PBR's experience in competition, this standard steel sprocket is designed for urban motorcycles and small-displacement bikes equipped with a 420 pitch chain. Built to last, it utilizes a high-quality 18NCD5 steel alloy, treated and machined according to a strict manufacturing process to ensure precise geometry and consistent engagement with the sprocket.
This sprocket offers good resistance to corrosion and abrasion while minimizing friction during engagement. Ideal for urban environments, it is suitable for original replacements or transmission revisions on small 50 cc and similar machines.
