DescriptionThe whole story

Dialling in the perfect chassis geometry is one of the most personal and time-sensitive tasks any track rider faces. The Spider Racing adjustable reaction rod and linkage for the Ducati Panigale V4/S (2025-2026) gives you a precision tool to fine-tune your suspension setup with confidence, ensuring that every session on the circuit starts from exactly the geometry that suits your riding style and the demands of the day.

Key Features

  • Machined from Ergal 7075 aluminium alloy — an aerospace-grade material chosen for its exceptional strength-to-weight ratio, delivering maximum rigidity without unnecessary mass.
  • Adjustable design allows precise, repeatable changes to the chassis geometry, so you can respond quickly to changing track conditions or personal preference.
  • Engineered specifically for the Ducati Panigale V4/S 2025-2026, ensuring a perfect OEM-quality fit with no adaptation required.
  • Developed for professional racing use, meeting the performance and durability demands of competitive track environments.
  • Straightforward installation thanks to exact fitment tolerances — spend more time riding and less time in the garage.

Track-Ready Geometry Control

The reaction rod is the link between your engine and swingarm that governs how anti-squat behaviour and chassis balance interact under acceleration. Spider Racing has re-engineered this component in Ergal 7075 — the same alloy trusted in aerospace and high-level motorsport — so you gain both the adjustability to personalise your setup and the structural integrity to sustain it lap after lap. Whether you are chasing tenths on a technical circuit or bedding in a new suspension configuration, this part lets you make measured, controlled changes rather than guessing.

Precision Fit, Professional Results

Part number 90.D323 is designed exclusively around the updated geometry of the 2025-2026 Ducati Panigale V4/S platform. The mounting points mirror the OEM specification precisely, so installation is clean, secure and repeatable. For teams and privateer racers who need to swap configurations between sessions, that consistency is not a luxury — it is a requirement.
