PBR Standard Steel Sprocket 565 - 520 (Manufacturer Part No: 565 17 18NC)
Designed by PBR based on its experience in competition, this 17-tooth sprocket is aimed at riders and mechanics looking for a robust part for chain transmission. Machined from high-quality steel (18NCD5 alloy), it offers increased resistance to corrosion and abrasion, with a finish and tolerances resulting from a strict manufacturing process.
Versatile, it fits on quads, motocross machines, and roadsters equipped with a 520 transmission. Its geometry and machining minimize friction between the sprocket and chain for a smoother ride and harmonious wear of the drivetrain. Ideal as a replacement part during routine maintenance or to reassemble a transmission after disassembly.
Before installation, check the chain pitch, number of teeth, and compatibility with your machine's sprocket and axle. Particularly suitable for use on Yamaha YZ 450 F, Kawasaki W 800, and CF Moto 700 CL-X Sport when specifications match.
