Ring gear Z42 P525 5 holes Ducati

More acceleration, bolder character. The Z42 P525 sprocket is CNC-machined from solid Ergal alloy and hard anodized for superior wear resistance. A popular choice for riders who want immediate responsiveness on corner exit without sacrificing drivetrain precision.

Rigid, reliable, with no weak points: the kind of component you only notice when it's gone.

Covers over three decades of Ducati models — from some of the most iconic Superbikes of the 90s through to the latest Hypermotard and Monster generations.

Compatibility and Installation

The Z42 P525 sprocket does not replace the original sprocket and is not compatible with the stock hub. Installation is only possible with the Sprocket Kit, which includes:

• Cush Drive Flange
• Z42 Sprocket
• Sprocket Nuts

Not just a replacement part — a deliberate choice made by riders who truly know their bike.
