PBR Standard Steel Sprocket 600M - 420 (Manufacturer Ref: 600M 15 18NC)
Designed by PBR, this steel sprocket 600M draws on experience gained in competition to offer a durable part suitable for urban and roadster use. Machined from a high-quality steel alloy 18NCD5, it resists corrosion and abrasion while minimizing friction within the transmission.
Ideal for replacing the sprocket on small displacement bikes and city/roadster-oriented machines, this sprocket offers easy installation and compatibility with several 50cc models from the 2025 range, including RIEJU MRT 50 SM, FANTIC XM 50 PERFORMANCE, and BETA RR 50 MOTARD. Its robust design is suitable for daily use, city rides, and short trips where transmission reliability is essential.
