Manufactured under a strict process, this sprocket features good resistance to corrosion and abrasion, helping to limit premature wear between the teeth and chain. Its black finish provides a neat appearance to the rear of the drivetrain and integrates easily into a replacement chain kit.

It directly replaces 43-tooth sprockets for 520 chains and is particularly suitable for roadsters and small displacement bikes. Possible fitments include: ZONTES 125Z2 (2025), ZONTES 125C (2025), and ZONTES 125 URBAN (2024). To maintain optimal transmission, check the condition of the sprocket and chain before installation and adhere to the torque specifications recommended by the manufacturer.
