Designed according to strict manufacturing processes, this sprocket offers good wear and corrosion resistance thanks to its quality steel. Surface treatments and careful machining help reduce friction and ensure a smooth finish of the teeth, allowing for a fluid engagement of the chain and increased longevity of the entire transmission system.

Compatible with many roadsters, it specifically fits models such as the SUZUKI DR 650 R DAKAR (1994), DR 650 RS (1991), and DR 600 S (1989). As a standard replacement part, it mounts in place of the original sprocket on 520 pitch transmissions. Ideal for maintenance or restoring your transmission chain.
