PBR Standard Steel Sprocket 2357 - 525: a sprocket designed for chain transmissions with a pitch of 525, intended for roadsters and demanding daily use. Manufactured by PBR, this 18-tooth sprocket combines durability and precision tooth design for reliable long-term performance.

• Material: steel (18NCD5 alloy) — high quality derived from the brand's competitive experience
• Number of teeth: 18
• Chain pitch: 525
• Color: black
• Type / Reference: 2357 / 2357 18 18NC

The 18NCD5 alloy provides excellent resistance to corrosion and abrasion, while the strict manufacturing process ensures a consistent tooth profile and precise fit on the chain and sprocket. This sprocket reduces internal friction within the transmission and contributes to controlled wear of the chain when properly installed and maintained.

Compatible with 525 pitch transmissions, it is suitable for roadsters and replaces standard sprockets during maintenance or gear ratio changes. Common applications include sport and road models equipped with similar transmissions, such as certain variants of the Kawasaki Z H2 and Ninja H2 SX SE (check exact compatibility with your model and year before ordering).
