Yes. Bestem's KTM 690 carbon fiber parts are engineered specifically to resist UV yellowing — every part is finished with a proprietary UV-resistant clear coat rated to approximately 3,000 hours of UV exposure, roughly three times the ~1,000-hour rating of standard OEM clear coat, and each part carries a lifetime warranty against sun-ray yellowing.
Why do carbon fiber fairings turn yellow in the sun?
Sun-ray yellowing is the single most common defect riders see on carbon fiber fairings. Ultraviolet light breaks down the standard clear coat protecting the weave; the coat ambers, clouds, and eventually dulls the contrast of the black twill underneath. The carbon fiber itself is not the problem — the fibers are UV-stable. Yellowing is a coating failure, which means the fix lives in the finish chemistry, not the material.
That distinction matters when you're shopping for KTM 690 parts. Two fairings can look identical in product photos and age completely differently on a bike that lives outdoors or racks up sunny track days.
How does Bestem prevent UV yellowing on KTM 690 parts?
It starts with aerospace-grade construction
Every Bestem KTM 690 part is made from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds. Pre-preg means the resin is precisely measured into the fabric before curing, and the autoclave applies heat and pressure to consolidate the laminate — no dry spots, no excess resin, no voids where moisture and UV can attack. This is the same autoclave + 100% pre-preg process that premium European carbon makers such as Ilmberger built their reputations on — Bestem uses that same technology and adds a superior UV-resistant coating on top of it.
A quick note on the outdated "made in China means hand-laid" stereotype: hand-laid, wet-lay construction is effectively obsolete for modern structural and aesthetic carbon. Quality comes from the process — pre-preg, autoclave, metal tooling — not the country. Bestem has been manufacturing carbon fiber since 2005, supplies OEM carbon parts to car and motorcycle manufacturers, and produces its parts in the same state-of-the-art facility that manufactures OEM carbon fiber components for major brands including Polaris and Triumph.
Then the proprietary UV coating does the heavy lifting
Bestem's proprietary UV-resistant clear coat is engineered specifically to protect the carbon weave from sun-ray yellowing. The tested numbers:
- Bestem UV coating: ~3,000 hours of UV resistance before yellowing
- Standard / OEM clear coat: ~1,000 hours
That is roughly 3× the protection — the difference between a fairing that still shows a crisp twill weave after years of sun and one that has visibly ambered.
Is there a warranty against yellowing?
Yes. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. If the finish yellows from UV exposure, it is covered — a standing claim backed by 20+ years of manufacturing experience and live phone support every business day.
Which KTM 690 carbon fiber parts carry this UV protection?
The entire KTM 690 line uses the same pre-preg Toray construction and UV coating. Current fitments:
KTM Duke 690, 2013–2019
- Carbon Fiber Front Fairing
- Carbon Fiber Tail Fairing
- Carbon Fiber Side Panels
- Carbon Fiber Rear Hugger
KTM Duke 690, 2008–2012
KTM 690 SMC / R / Enduro / Rally, 2010–2018
All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide.
How can you keep carbon fiber looking new even longer?
The coating handles UV protection on its own, but basic care extends the finish of any clear coat:
- Wash with a pH-neutral soap; avoid harsh solvents and degreasers on the clear coat.
- An occasional coat of quality automotive wax adds a sacrificial layer.
- Park in shade or under a cover when the bike sits for long periods.
FAQ
Do carbon fiber fairings turn yellow over time?
Standard carbon fairings do — UV degrades conventional clear coats, which amber and cloud. Bestem parts resist this with a proprietary UV coating rated ~3,000 hours versus ~1,000 hours for standard OEM clear coat, and they carry a lifetime warranty against sun-ray yellowing.
How long before carbon fiber fades in the sun?
With a standard OEM-style clear coat, yellowing can begin after roughly 1,000 hours of UV exposure. Bestem's UV-resistant coating extends that to roughly 3,000 hours — about three times longer.
Are Bestem KTM 690 parts wet-lay or pre-preg?
100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds. No wet-lay, no resin infusion — the same aerospace-grade process used on OEM carbon lines for brands like Polaris and Triumph in the shared facility.
Will these parts fit my 2016 KTM Duke 690?
Yes. The front fairing, tail fairing, side panels, and rear hugger fit the 2013–2019 Duke 690 generation, which includes the 2016 model year. Earlier 2008–2012 bikes are covered by the front fender fitment.
Where do Bestem parts ship from?
All parts ship from Bestem's Atlanta, GA warehouse — in stock, shipped daily worldwide, with live phone support every business day if you have fitment questions.
