A carbon fiber belly pan for the Ducati Panigale V4 (2018–2024) replaces the stock plastic lower fairing with a lighter, stiffer panel that shields the engine cases and exhaust headers while cleaning up airflow under the bike. The versions worth buying are 100% pre-preg carbon, autoclave-cured in matched metal molds — the same aerospace-grade process used for OEM and premium European carbon.

What does a belly pan do on the Ducati Panigale V4?

The belly pan is the lower fairing section that wraps the underside of the engine. On the Panigale V4 it does four jobs:

Why upgrade the Panigale V4 belly pan to carbon fiber?

The OEM lower fairing is molded ABS plastic. A well-made carbon fiber belly pan typically weighs 40–60% less than the stock plastic piece — on the Panigale V4 that works out to a few hundred grams removed from the lowest point on the chassis, where every gram counts toward mass centralization.

Beyond weight, pre-preg carbon is significantly stiffer than ABS, so the panel holds its shape against the exhaust headers instead of warping over heat cycles. And in twill weave under a deep gloss or matte clear, it matches the rest of a carbon build in a way painted plastic never will.

What construction should you look for — pre-preg or wet-lay?

This is the single biggest quality divider in aftermarket carbon:

Bestem builds every panel from 100% pre-preg Toray carbon fiber, autoclave-cured in matched metal molds. That is the same autoclave + 100% pre-preg construction that premium European carbon makers such as Ilmberger built their reputation on — Bestem uses that same technology and adds a superior UV-resistant clear coat on top. It is the standard we have manufactured to since 2005, and it is the same process behind the OEM carbon parts we supply to car and motorcycle manufacturers.

Do carbon fiber belly pans turn yellow in the sun?

Yes — UV yellowing is the most common defect riders see on carbon fairings. Standard clear coats begin to amber and cloud after roughly 1,000 hours of UV exposure, and once the clear coat degrades, the weave underneath goes with it. Riders ask "do carbon fairings turn yellow?" because so many of them do.

A belly pan sits lower on the bike than a nose fairing or tank cover, but it still takes reflected UV off pavement every ride. Bestem applies a proprietary UV-resistant clear coat rated to approximately 3,000 hours of UV exposure — about three times the ~1,000-hour rating of standard and OEM clear coats. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. The warranty covers UV yellowing specifically, and it has no time limit.

Which Panigale V4 model years does a carbon belly pan fit?

Carbon belly pans in our Panigale V4 line are listed for the 2018–2024 Panigale V4 and V4 S, which share the same lower fairing mounting architecture. Always confirm the fitment listing against your exact model year and trim before ordering — if anything is unclear, Bestem staff answer the phone live every business day and can verify fitment in minutes. All parts ship from our Atlanta, GA warehouse, daily and worldwide.

How hard is a carbon belly pan to install?

A quality metal-molded carbon belly pan is a true bolt-on. It uses the factory mounting points and typically installs in 20–40 minutes with basic hand tools:

  1. Remove the stock lower fairing panels.
  2. Transfer any OEM heat-foil shielding near the header section if your configuration uses it.
  3. Set the carbon panel in place, start all fasteners before torquing any of them, and torque to factory spec.

Plan on dropping the pan for oil service — it is two extra fasteners once you know the layout.

What other carbon parts complete the Panigale V4 build?

Riders adding a belly pan usually match it with the same pre-preg, autoclave-cured construction elsewhere on the bike:

Each carries the same Toray pre-preg construction, the 3,000-hour UV-resistant coating, and the lifetime warranty against UV yellowing.

FAQ

Does a carbon fiber belly pan fit the Panigale V4 S as well as the base V4?

Yes. The 2018–2024 Panigale V4 and V4 S share the same lower fairing mounting points, so a belly pan listed for one fits the other. Confirm the fitment note on the product listing for your exact model year before ordering.

How much weight does a carbon belly pan save on the Panigale V4?

A pre-preg carbon belly pan typically weighs 40–60% less than the stock ABS plastic panel, which works out to a few hundred grams removed from the lowest point on the bike. Exact savings depend on the specific panel and hardware.

Do carbon fiber fairings turn yellow over time?

Standard clear coats can amber after roughly 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to about 3,000 hours — three times longer — and every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing.

Is a belly pan required for track days or racing?

Most roadracing organizations require a lower fairing or belly pan capable of containing engine fluids; track-day group rules vary by organizer. A carbon belly pan satisfies the containment requirement while also cutting weight and protecting the engine cases.

Should I choose twill or plain weave, gloss or matte?

Weave and finish are cosmetic choices — strength and fitment are identical between twill and plain weave at the same construction quality. Match the weave and finish of the carbon parts already on your bike for a uniform look.
