Ring gear ergal Z38 P520 6 holes for Ducati

The Z38 520 pitch sprocket is designed for riders looking for a longer final drive ratio and smoother power delivery, ideal for high-speed use and performance-oriented setups.

With 38 teeth and 520 pitch, this configuration optimizes top-end performance and reduces engine RPM at higher speeds, making it perfect for advanced racing setups or specific builds where every drivetrain detail matters.

Machined from solid Ergal 7075 T6, a high-strength aluminum alloy, and finished with deep hard anodizing, it ensures excellent wear resistance, structural stability, and long-term durability even under intensive use.

High-precision CNC machining guarantees perfect concentricity, reduced rotating mass, and more direct, efficient power transmission.
