PBR Standard Steel Sprocket - 428 — Manufacturer's ref: 4513 43 C45
Designed for road transmissions, this PBR steel sprocket is aimed at riders looking for a robust and reliable part for their transmission. Machined from high-quality 18NCD5 steel alloy, it offers good resistance to wear and corrosion while maintaining a tooth profile compliant with the 428 pitch.
PBR relies on competitive experience and a strict manufacturing process: controlled heat treatment, precise machining, and repeated quality control. These elements help to limit friction and wear between the sprocket, the pinion, and the chain, for an optimized lifespan in road use. The black finish facilitates aesthetic integration on modern roadsters.
Compatibility (examples): YAMAHA R125 (2025), YAMAHA MT-125 (2025), YAMAHA XSR 125 LEGACY (2024). Always check the chain pitch and the required number of teeth for your model before installation.
