Z39 P525 Modular Rear Sprocket - High-Performance Ergal for MV Agusta

Modular rear sprocket (39 teeth, 525 pitch) machined from solid billet Ergal. This version is the technical choice for riders looking to optimize their final drive ratio, ensuring superior smoothness and a sharper response compared to the stock setup.

• Billet Machining: CNC manufactured to eliminate imperfections and guarantee perfect concentricity.
• Hard-Coat Treatment: The hard anodizing isn't just for looks; it creates a surface shield that protects the tooth profile from chain friction.
• Modular System: Designed for 100% interchangeability. Compatible with CNC Racing FC301 / FC302 flanges and the original OEM component.
• Mechanical Efficiency: The lightweight Ergal reduces inertia, allowing the rear wheel to transfer power to the ground more effectively.

Mechanical precision and superior durability for total traction control.
