Yes — provided the clear coat is engineered for UV exposure. Carbon fiber itself doesn't yellow; it's the resin system and top clear coat that amber and cloud under sunlight. Bestem's carbon fiber parts for the Can-Am Spyder RS-S are finished with a proprietary UV-resistant clear coat rated to roughly 3,000 hours of UV exposure — about three times the ~1,000-hour rating of a standard OEM clear coat — and every part carries a lifetime warranty against sun-ray yellowing.

Why do carbon fiber parts turn yellow in the sun?

Yellowing is almost never a problem with the carbon weave itself — carbon strands are essentially inert to ultraviolet light. The weak link is what sits on top of and between them: the epoxy resin and the clear coat. Under sustained UV exposure, low-grade resins and generic automotive clears oxidize, taking on a yellow-brown tint that dulls the weave and makes the part look aged.

Wet-laid parts with a thin sprayed-on clear are the worst offenders — some start ambering within a season or two of regular outdoor parking. That matters on a machine like the Spyder RS-S, which tends to live outside at rallies, hotels, and driveways rather than under a cover in a climate-controlled garage. UV hours accumulate fast on a touring three-wheeler.

How are Bestem Spyder RS-S carbon parts built to resist yellowing?

What construction process does Bestem use?

Every Bestem part is made from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds. Pre-preg means the resin content is precisely controlled at the fiber level — no resin-rich pockets that degrade unevenly, no dry spots. Autoclave curing under heat and pressure produces a dense, void-free laminate with consistent surface quality. 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 technology and adds a superior UV-resistant coating on top of it.

How long does the UV coating actually last?

Bestem's proprietary UV-resistant clear coat is rated to approximately 3,000 hours of UV exposure, versus roughly 1,000 hours for standard OEM clear coat — about three times longer before sun-ray yellowing appears. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. For a part that bolts onto a machine ridden in open sun, that is the single most relevant durability figure you can compare.

Which carbon fiber parts can you add to a Spyder RS-S?

Bestem's Spyder carbon line is 100% twill-weave carbon, built with the pre-preg and autoclave process described above:

The RS-S is the sport trim of the Spyder RS platform and shares its core bodywork, but always confirm year-specific fitment on the product page before ordering. Bestem staff answer the phone live every business day if you want fitment verified against your model year.

How do you keep Spyder carbon fiber looking new long-term?

Bestem has been manufacturing carbon fiber since 2005 — over 20 years — and supplies OEM carbon parts to car and motorcycle manufacturers alongside its aftermarket line. All Spyder parts are stocked in Bestem's Atlanta, GA warehouse and ship daily worldwide, so the part you order is on the shelf, not on a container ship.

FAQ

Do carbon fiber fairings turn yellow over time?

Cheap ones do. The yellowing riders see is the clear coat and resin ambering under UV, not the carbon itself. Standard OEM-style clears are typically rated around 1,000 hours of UV exposure; Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours — about three times longer before any sun-ray yellowing appears.

Is sun-ray yellowing covered under warranty?

Yes. Bestem carbon fiber parts carry a lifetime warranty against sun-ray (UV) yellowing, made possible by the proprietary UV-resistant clear coat applied to every part.

Will Bestem carbon parts fit my Spyder RS-S?

Bestem's Spyder carbon line is listed for the Spyder RS platform — the windshield, for example, covers 2008-2016 — and the RS-S shares the RS bodywork. Confirm your exact model year on the product page, or call Bestem during business hours; live staff answer the phone every business day.

How long before carbon fiber fades in direct sunlight?

With a standard clear coat, expect visible ambering after roughly 1,000 hours of UV exposure. Bestem's coating extends that to approximately 3,000 hours, and the pre-preg, autoclave-cured laminate underneath resists the surface degradation that makes cheaper parts look cloudy with age.

Where do Bestem Spyder parts ship from?

All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide. Bestem has manufactured carbon fiber since 2005 and also supplies OEM carbon components to car and motorcycle manufacturers.
