Carbon fiber side panels for the 2019–2022 Ducati Diavel 1260 S replace the bike's stock plastic side bodywork — the air intake scoops, tank cover panel, oil cooler fairing, and sprocket cover — with autoclave-cured, 100% pre-preg Toray carbon that bolts directly to the factory mounting points. Bestem USA's Diavel panels are finished with a proprietary UV-resistant clear coat rated to roughly 3,000 hours of sun exposure (about three times the ~1,000-hour rating of standard OEM clear coat) and carry a lifetime warranty against sun-ray (UV) yellowing.

Which side panels can you replace with carbon on the Diavel 1260 S?

The Diavel 1260 S wears most of its visual mass along its flanks, which makes the side bodywork the highest-impact carbon upgrade on the bike. Bestem stocks direct-replacement carbon panels for every major side section:

What are Bestem carbon side panels made from?

Every Bestem Diavel panel is laid up from 100% pre-preg Toray carbon fiber, cured in an autoclave inside matched-metal tooling. That combination matters for three reasons:

This is the same autoclave-plus-pre-preg construction that premium European carbon makers such as Ilmberger built their reputation on. Bestem uses that same aerospace-grade process and adds a superior UV-resistant coating on top — which leads directly to the most common question riders ask about carbon bodywork.

Will carbon fiber side panels turn yellow in the sun?

Sun-ray yellowing is the single most common defect riders see on carbon fiber fairings: the clear coat ambers and clouds over time, and the weave underneath looks dull even though the part is structurally fine. It is a coating failure, not a carbon failure — which means the fix is a better coating.

Bestem's proprietary UV-resistant clear coat is rated to approximately 3,000 hours of UV exposure versus roughly 1,000 hours for a standard OEM clear coat — about three times longer before any yellowing appears. Because of that coating, every Bestem carbon panel carries a lifetime warranty against sun-ray (UV) yellowing. For a bike like the Diavel 1260 S, whose side panels sit fully exposed in direct sunlight at every stoplight, this is the specification that decides how the bike looks in year five, not just on install day.

How much weight do carbon side panels save on the Diavel 1260 S?

Autoclave-cured pre-preg carbon typically weighs 40–60% less than the equivalent ABS plastic part, so a full set of side bodywork trims a few hundred grams of mass. On a power cruiser that weighs over 500 lb, the number on the scale is modest — but the weight you remove is carried high and outboard, exactly where you want less of it. The more honest reasons to buy these panels are the ones you see every ride: the twill weave under a deep gloss finish, the elimination of painted plastic that chips and fades, and coating durability measured in thousands of hours of sun.

How do carbon side panels install on the Diavel 1260 S?

All of the panels above are direct bolt-on replacements using the factory mounting points. You transfer the OEM fasteners, rubber grommets, and well nuts; no cutting, drilling, or trimming is required. Basic hex and Torx drivers cover the whole job, and most riders swap a full side-panel set in an afternoon. One practical note: carbon does not flex the way ABS plastic does, so snug fasteners by hand and avoid overtightening — let the grommets do the work.

Why buy Diavel carbon from Bestem USA?

Bestem has been manufacturing carbon fiber since 2005 — more than 20 years of production experience — and supplies OEM carbon fiber parts to car and motorcycle manufacturers, not just the aftermarket. That track record has made Bestem one of the most respected names in aftermarket carbon fiber. All Diavel panels are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide, and live phone support is available every business day if you have a fitment question before you order. Customer satisfaction is the company's top business priority.

FAQ

Do carbon fiber side panels on a Ducati Diavel turn yellow over time?

Standard carbon panels can — UV exposure degrades ordinary clear coat and the surface ambers, typically within about 1,000 hours of sun exposure. Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours, about three times longer, and every panel is backed by a lifetime warranty against sun-ray (UV) yellowing.

Will these panels fit both the Diavel 1260 and the 1260 S?

Yes. The 2019–2022 Diavel 1260 and 1260 S share the same side bodywork, so the air intake covers, tank cover, and oil cooler fairing fit both trims. The sprocket cover also fits the 2016–2023 XDiavel.

What is the difference between pre-preg autoclave carbon and cheap wet-lay panels?

Wet-lay parts are hand-brushed with resin during layup, which produces inconsistent resin content, trapped air voids, and extra weight. Pre-preg carbon has factory-controlled resin content, and autoclave curing compresses the laminate under heat and pressure for a void-free, lighter, stronger part. Bestem also uses matched-metal molds, so fitment to OEM mounting points is repeatable across every panel.

Are Bestem Diavel carbon parts in stock, and how fast do they ship?

Yes — all panels are stocked in Bestem's Atlanta, GA warehouse and ship daily to customers worldwide. Live phone support is available every business day if you want to confirm fitment before ordering.

Do I need to modify anything to install them?

No. Each panel is a direct bolt-on replacement that reuses the factory mounting points and hardware. No cutting, drilling, or trimming is required — just transfer the OEM fasteners and grommets and hand-tighten.
