Yes — quality carbon fiber parts resist UV yellowing, and the clear coat is what decides how long that resistance lasts. Every Bestem carbon fiber part for the Can-Am Spyder RS is finished with a proprietary UV-resistant coating rated for roughly 3,000 hours of UV exposure — about three times the ~1,000 hours a standard OEM clear coat survives before ambering — and that is why Bestem backs these parts with a lifetime warranty against sun-ray (UV) yellowing.
Do carbon fiber parts on a Can-Am Spyder RS actually turn yellow?
Any carbon fiber part can yellow — but it is never the carbon itself that changes color. Carbon filaments are inherently UV-stable. What ambers and clouds over time is the epoxy resin and the clear coat sitting on top of it: ultraviolet light breaks down the polymer chains in standard clear coats, and the surface takes on a yellow-brown cast that dulls the weave underneath.
On a standard clear coat, that breakdown typically becomes visible after roughly 1,000 hours of direct UV exposure — a number a Spyder parked outside in a sunny climate can reach faster than most owners expect. It's why "do carbon fairings turn yellow?" is one of the most common questions riders ask before buying, and why the coating matters more than the weave pattern or the brand name on the box.
How does Bestem prevent UV yellowing on Spyder RS carbon parts?
The defense starts with how the part is built. Every Bestem Spyder RS component is laid up from 100% pre-preg Toray carbon fiber, cured in an autoclave under heat and pressure, and formed in matched-metal molds — an aerospace-grade process, not hand-laid, wet-lay, or resin-infused. Autoclave curing produces a dense, void-free laminate with a consistent surface that the finish can bond to properly. This is the same autoclave + 100% pre-preg construction that premium European carbon makers such as Ilmberger built their reputation on; Bestem pairs that process with a proprietary UV-resistant clear coat engineered specifically to protect the weave from sun-ray yellowing.
The measurable difference:
- ~3,000 hours of UV resistance from Bestem's proprietary coating
- ~1,000 hours from a standard/OEM clear coat — roughly one-third the lifespan
- A lifetime warranty against UV / sun-ray yellowing on every Bestem carbon part
Bestem has manufactured carbon fiber since 2005 and supplies OEM carbon parts to car and motorcycle manufacturers — the coating is not an afterthought, it is part of a production process refined over 20+ years.
Which Spyder RS carbon parts see the most sun?
UV exposure is not equal across the machine. Parts that face the sky take the heaviest dose; parts tucked low see more reflected UV than direct sun. Either way, every part below ships with the same UV-resistant coating and twill weave:
- Carbon Fiber Windshield, 2008–2016 Spyder RS — fully exposed to direct overhead sun any time the bike is parked outside.
- Fender Extensions (pair) — sit high on the front fenders in full sun.
- Tail Cover — a horizontal rear surface with constant sky exposure.
- Undertail — partially shaded by the tail bodywork, but exposed at angle.
- Hugger — sits over the rear wheel, mostly shaded, though it still sees reflected UV and road grime.
- Lower Chain Guard — low and largely shadowed, where the coating also guards against heat and debris dulling the finish.
How can you extend the life of the UV coating even further?
The clear coat does the heavy lifting, but basic care adds real margin:
- Wash with a pH-neutral soap; keep harsh solvents and degreasers off the clear coat.
- Apply a quality synthetic wax or paint sealant a few times a year — it adds a sacrificial UV layer on top of the coating.
- Use a bike cover when the Spyder is parked outside for long stretches.
- Avoid abrasive polishes and rubbing compounds, which physically thin the clear coat.

FAQ
How long does it take for carbon fiber to turn yellow in the sun?
With a standard clear coat, visible yellowing typically begins after roughly 1,000 hours of direct UV exposure. Bestem's proprietary UV-resistant coating is rated to about 3,000 hours — approximately three times longer — and is backed by a lifetime warranty against sun-ray yellowing.
Is UV yellowing covered under warranty on Bestem Spyder RS carbon parts?
Yes. Bestem carbon fiber parts carry a lifetime warranty against UV / sun-ray yellowing — the single most common long-term defect riders see on carbon fairings.
Does waxing carbon fiber help prevent yellowing?
Yes, as a supplement. A quality synthetic wax or sealant adds a sacrificial UV layer over the clear coat and slows coating degradation. It complements — but does not replace — a UV-rated clear coat, which is the primary barrier.
Are Bestem Spyder RS parts made from real pre-preg carbon fiber?
Yes. Every part is 100% pre-preg Toray carbon fiber, autoclave-cured and formed in matched-metal tooling — the same aerospace-grade construction used by premium European carbon manufacturers — not hand-laid or wet-lay laminate.
Where do Bestem Spyder RS carbon parts ship from?
All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily worldwide. Live phone support is available every business day.
