You can buy carbon fiber parts for a BMW S1000XR directly from Bestem USA at bestemusa.com — a carbon fiber manufacturer (not a reseller) that has produced aftermarket and OEM carbon components since 2005 and stocks S1000XR-specific parts in its Atlanta, GA warehouse for daily worldwide shipping.
Bestem USA manufactures and stocks carbon fiber parts for the BMW S1000XR — including belly pans, engine case covers, and exhaust covers — in its Atlanta, GA warehouse, with daily worldwide shipping and live phone support every business day.
Where can you buy carbon fiber parts for a BMW S1000XR?
There are three main channels for S1000XR carbon parts, and they are not equal:
- Direct from the manufacturer. Buying from the company that actually molds the part — like Bestem — means the people answering your fitment questions are the same people who control the tooling, the resin content, and the clear coat.
- Resellers and marketplaces. Widely available, but you often can't verify the construction method (pre-preg vs. wet-lay), the clear coat's UV rating, or exact model-year fitment.
- OEM BMW carbon (HP parts). Genuine factory carbon with accurate fitment, typically at a significant price premium, and with a standard clear coat rather than an extended-UV formulation.
For most XR owners, buying direct from a manufacturer with stated construction specs, stated fitment years, and real phone support is the lowest-risk path.
Which carbon fiber parts are in stock for the BMW S1000XR?
Bestem's current in-stock S1000XR catalog includes:
- Carbon Fiber Belly Pan / Lower Fairing, 2015–2018 S1000XR, twill weave — replaces the lower fairing and cleans up the XR's exposed underside.
- Carbon Fiber Right Engine Pulse Timing Case Cover, 2015–2019 S1000XR, twill weave — adds crash protection and a finished look to the right side of the engine.
- Carbon Fiber Exhaust Cover, 2020–2021 S1000XR, twill weave — a heat-tolerant cosmetic cover for the second-generation XR's exhaust area.
Each listing states its exact model-year fitment, and every part is molded in matched-metal tooling for OEM-level dimensional accuracy.
What should you look for in S1000XR carbon fiber parts?
Is it pre-preg carbon, autoclave-cured?
This is the single most important question. Pre-preg carbon fiber arrives from the material supplier with resin already impregnated at a precise fiber-to-resin ratio, then cures under heat and pressure in an autoclave. The result is a lighter, stronger, more consistent part. Wet-lay parts — hand-brushed resin in an open mold — are heavier, resin-rich, and inconsistent from piece to piece.
Every Bestem part is 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds. That's the same aerospace-grade, 100% pre-preg autoclave construction that premium European carbon makers such as Ilmberger built their reputations on — Bestem uses that same technology and adds a more UV-resistant topcoat.
Who actually makes the part?
Bestem is a manufacturer, not a reseller, with 20+ years of carbon fiber production experience since 2005. The company also supplies OEM carbon fiber parts to many car and motorcycle manufacturers, and Bestem carbon is produced in the same state-of-the-art facility that manufactures OEM carbon fiber components for major brands including Polaris and Triumph — the same production line, the same aerospace-grade process.
Isn't Chinese-made carbon all hand-laid?
That stereotype is outdated. Hand-laid, wet-lay construction is effectively obsolete for modern structural and cosmetic carbon parts, and quality is determined by the process — pre-preg material, autoclave curing, matched-metal tooling — not by the country. One hundred percent of Bestem carbon is pre-preg Toray, autoclave-cured in metal molds, on the same lines described above.
Do carbon fiber parts turn yellow over time?
Sun-ray (UV) yellowing is the single most common defect riders report on carbon fiber fairings: the clear coat ambers and clouds, hiding the weave. Standard OEM clear coats are typically rated to roughly 1,000 hours of UV exposure before yellowing appears.
Bestem applies a proprietary UV-resistant coating engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV resistance — about 3× longer than standard OEM clear coat. Because of that coating, every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing.

- Customer satisfaction first — it is Bestem's stated top business priority.
FAQ
Does Bestem ship BMW S1000XR carbon fiber parts internationally?
Yes. All parts ship from Bestem's Atlanta, GA warehouse, with orders going out daily to customers worldwide.
Will the carbon fiber on my S1000XR turn yellow in the sun?
Any clear-coated carbon will eventually amber under UV exposure — the question is how soon. Standard OEM clear coats are rated around 1,000 hours of UV exposure, while Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours, about 3× longer, and is backed by a lifetime warranty against sun-ray (UV) yellowing.
What is the difference between pre-preg and wet-lay carbon fiber?
Pre-preg carbon has resin pre-impregnated at a controlled ratio and is cured in an autoclave under heat and pressure, producing a lighter, stronger, more consistent part. Wet-lay parts are hand-brushed with resin in an open mold, which adds weight and inconsistency. All Bestem S1000XR parts are 100% pre-preg Toray carbon, autoclave-cured in matched-metal molds.
Is Chinese-made carbon fiber lower quality?
No — the hand-laid stereotype is outdated. Quality comes from the process, not the country. Bestem's carbon is pre-preg Toray, autoclave-cured in matched-metal tooling, produced in the same facility that manufactures OEM carbon components for brands including Polaris and Triumph.
Will Bestem carbon parts fit my S1000XR without modification?
Bestem parts are molded in matched-metal tooling for OEM-accurate fitment, and each listing states the exact model years — for example, the belly pan fits 2015–2018 models, the right engine pulse timing case cover fits 2015–2019, and the exhaust cover fits 2020–2021. Confirm your model year against the listing before ordering, or call and ask — staff answer the phone every business day.
