DescriptionThe whole story▼
Autoclave-cured and race-proven, the Fullsix upper cylinder head covers bring genuine motorsport-grade carbon fibre to the Ducati Panigale V4/S (2025-2026) — delivering measurable weight reduction, superior heat management, and a finish that meets the same standards demanded by factory racing teams. These are not replicas or carbon-look laminates; every panel is constructed from authentic carbon fibre, processed under controlled autoclave conditions for maximum structural integrity.
Key Features
- Genuine 100% carbon fibre construction — autoclave-manufactured for uncompromising strength-to-weight ratio
- UV-resistant and heat-stable — engineered to resist discolouration and warping even under sustained track conditions
- Direct OEM replacement — plug-and-play fitment with no cutting, drilling or modification required
- Precision-matched to Ducati Panigale V4/S cylinder head contours for a seamless, factory-quality appearance
- Improved heat dissipation around the cylinder head area compared to standard plastic covers
- Available in multiple weave patterns and finishes to suit personal preference and aesthetic goals
Autoclave Construction and Material Quality
Fullsix produces these covers using the same autoclave process applied in aerospace and factory motorsport programmes. Under high pressure and controlled temperature, the carbon layers are consolidated without voids or delamination, resulting in panels that are both structurally reliable and visually flawless. The absence of fillers or backing plastics keeps mass to an absolute minimum — directly contributing to reduced unsprung and engine-area weight on your Panigale V4/S.
Finish Options and Part Numbers
The covers are offered in two weave structures — 200 Plain and 245 Twill — and across four surface finishes, allowing riders to match their existing carbon bodywork or choose a contrasting texture. The 200 Plain weave produces a tight, uniform grid pattern, while the 245 Twill delivers the classic diagonal carbon aesthetic. Available finishes and corresponding part numbers are listed below.
- 200 Plain / Glossy — MD-V425-C77
- 200 Plain / Matte — MD-V425-M77
- 200 Plain / Raw (untreated) — MD-V425-R77
- 200 Plain / Satin — MD-V425-S77
- 245 Twill / Glossy — MD-V425-TC77
Fitment and Compatibility
These upper cylinder head covers are precision-engineered exclusively for the following models:
- Ducati Panigale V4 — model years 2025 and 2026
- Ducati Panigale V4 S — model years 2025 and 2026
No modification to the motorcycle is required. The covers replace the original equipment parts on a direct one-to-one basis, using existing mounting points and hardware.
