PBR Standard Steel Sprocket 7005 - 420 (manufacturer part number: 7005 13 18NC): a sprocket designed for off-road and motocross use. Made from competition-grade 18NCD5 alloy steel, it aims for high resistance to corrosion and abrasion while adhering to a strict manufacturing process for a consistent finish on the teeth.
This sprocket is aimed at motocross riders looking for a reliable transmission part for their track outings. Its design minimizes friction at the teeth and withstands the demands of off-road riding: repeated starts, changes in RPM, and abrasive terrains.
Common compatibilities: suitable for small displacement motocross bikes like KTM 65 SX, HUSQVARNA TC 65, and GAS GAS MC 65 (2025 models). Before installation, check the number of teeth and the chain pitch of your setup to ensure compatibility with your rear sprocket and chain.
