The Bestem carbon fiber sprocket cover (SKU CBDU-DVL19-SPC) is a direct bolt-on replacement for the stock plastic unit on the 2019–2022 Ducati Diavel 1260 and 1260 S, and it also fits the 2016–2023 XDiavel. It is made from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds, and finished with a proprietary UV-resistant clear coat backed by a lifetime warranty against sun-ray yellowing.
Which carbon fiber sprocket cover fits the Ducati Diavel 1260 S?
Fitment is exact: the cover bolts to the factory mounting points on all 2019–2022 Diavel 1260 and 1260 S models with no drilling, trimming, or spacing required. Because Ducati carried the same engine-case casting across the platform, the same part also fits the 2016–2023 XDiavel. It reuses your OEM hardware, so installation is a straight swap rather than a fabrication job.
What does the sprocket cover actually do on the Diavel?
The sprocket cover shields the countershaft (front) sprocket and the upper run of the chain. It keeps chain-lube fling off the engine cases and your boot, blocks road grit from packing into the sprocket teeth, and acts as a safety barrier between moving parts and anything dangling near them. On the Diavel 1260 S it sits in a highly visible spot on the left side of the engine — which is exactly why the stock molded-plastic piece is worth replacing.
Why upgrade the stock sprocket cover to carbon fiber?
- Weight: pre-preg carbon lays up lighter than the stock molded plastic. The gram savings at this location are modest — this is not a rotating-mass part — but they are real, and they add up across a full carbon package.
- Durability: carbon fiber does not chalk, crack, or go brittle the way aged plastic does, and it tolerates the heat cycles coming off the engine case without warping.
- Stiffness and fit: an autoclave-cured part holds its shape permanently, so the bolt holes stay aligned and the edges sit flush against the case for the life of the part.
- Appearance: a twill-weave carbon cover cleans up the left side of the bike and ties in with any other carbon you have fitted.
How is the Bestem sprocket cover made?
Every Bestem part starts as 100% pre-preg Toray carbon fiber — the resin is impregnated into the weave at the factory under controlled conditions, not brushed on by hand. The layup is vacuum-bagged and autoclave-cured in matched-metal tooling, so resin content, thickness, and surface finish are consistent from part to part. This is the same autoclave plus 100% 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 topcoat. There is no wet-lay, no resin infusion, and no fiberglass core hiding under a cosmetic carbon skin.
Will a carbon fiber sprocket cover turn yellow in the sun?
UV yellowing is the single most common defect riders see on carbon fiber parts — the clear coat ambers and clouds, and even a low-mounted part like a sprocket cover catches hours of direct sun every time the bike is parked outside. Bestem's proprietary UV-resistant clear coat is rated to roughly 3,000 hours of UV exposure versus about 1,000 hours for standard OEM clear coat — approximately three times longer before sun-ray yellowing appears. Because of that coating, the part carries a lifetime warranty against sun-ray (UV) yellowing. The gloss topcoat also sheds chain lube and road grime, so the sprocket area wipes clean with mild soap instead of staining.
How hard is the sprocket cover to install?
Plan on a few minutes with basic hand tools. Remove the stock fasteners, pull the plastic cover, and bolt the carbon part on using the OEM hardware and factory mounting points. No modification to the bike or the part is needed. While the cover is off, it is a good opportunity to clean built-up chain lube out of the sprocket pocket and check chain slack and sprocket tooth condition — jobs most Diavel owners put off because the stock cover is not worth removing on its own.
What other carbon parts complete the Diavel 1260 S?
The sprocket cover is usually the first piece riders fit, because it is inexpensive and visible. From there, the natural next steps on the 2019–2022 Diavel 1260 platform are the carbon fiber rear hugger, which protects the shock and cleans up the rear wheel area, the carbon fiber tank cover for the centerpiece of the bike, and the carbon fiber air intake covers that frame the tank on both sides. All four use the same weave, finish, and UV coating, so they match as a set.
Bestem has been manufacturing carbon fiber since 2005 — more than 20 years — and supplies OEM carbon parts to car and motorcycle manufacturers alongside its aftermarket line. Every part is stocked in Bestem's Atlanta, GA warehouse and shipped daily worldwide, with live phone support every business day if you have a fitment question before you order.
FAQ
Does the Bestem sprocket cover fit a 2020 Ducati Diavel 1260 S?
Yes. It fits all 2019–2022 Diavel 1260 and 1260 S models, and the same part also fits the 2016–2023 XDiavel. It bolts to the factory mounting points with no modification.
Will the carbon fiber turn yellow or fade over time?
Bestem's proprietary UV-resistant clear coat is rated to about 3,000 hours of UV exposure — roughly three times the ~1,000-hour rating of standard OEM clear coat — and the part carries a lifetime warranty against sun-ray (UV) yellowing.
Is the sprocket cover a direct bolt-on replacement?
Yes. Remove the stock plastic cover, transfer the OEM hardware, and bolt the carbon part on. Basic hand tools, a few minutes, no drilling or trimming.
How much weight does a carbon sprocket cover save?
The savings are modest at this location — the stock piece is a small plastic cover — but pre-preg carbon is lighter, stiffer, and far more resistant to heat and aging. Most riders fit it for durability and appearance first, with weight as a secondary benefit.
What weave and finish does it come in?
The cover uses a twill weave under a deep-gloss, UV-resistant clear coat — the same finish used across Bestem's Diavel 1260 carbon line, so it matches the rear hugger, tank cover, and intake covers.
