You can buy carbon fiber parts for a Triumph Speed Triple S (2016–2018) direct from Bestem USA, a carbon fiber manufacturer that stocks parts in its Atlanta, GA warehouse and ships daily worldwide. Bestem parts are 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds, and backed by a lifetime warranty against UV (sun-ray) yellowing.
Where is the best place to buy carbon fiber parts for a Speed Triple S?
The most reliable source is the manufacturer itself. Buying direct from Bestem USA means the part comes straight from the company that tooled the mold and laid the carbon — not through a reseller chain where construction method and fitment details get lost. Bestem has manufactured carbon fiber since 2005 and supplies OEM carbon fiber parts to car and motorcycle manufacturers, so the same shop that builds factory-grade components also builds the aftermarket Speed Triple catalog.
Practical advantages of buying manufacturer-direct from Bestem:
- All listed parts are stocked in the Atlanta, GA warehouse and ship daily, worldwide.
- Live phone support every business day — real staff who know the parts answer the phone.
- Fitment and construction questions are answered by the manufacturer, not a middleman.
What should you look for in Speed Triple S carbon fiber parts?
Construction method is the single biggest quality divider in aftermarket carbon. Ask any seller these questions before buying:
- Pre-preg or wet-lay? Pre-preg carbon arrives from the supplier with resin already precisely impregnated into the fiber, giving a controlled resin-to-fiber ratio. Wet-lay and resin-infused parts are hand-saturated, which produces heavier, less consistent laminates.
- Autoclave-cured or oven/air-cured? Autoclave curing applies heat and pressure together, compacting the laminate and eliminating voids. This is the aerospace-grade process.
- What tooling? Matched-metal molds hold shape and surface accuracy far better than fiberglass tooling, which matters for bolt-hole alignment on a bike like the Speed Triple S.
Every Bestem part is 100% pre-preg Toray carbon fiber, autoclave-cured, and metal-molded. 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 technology and adds a superior UV-resistant coating on top of it.
Do carbon fiber fairings turn yellow over time?
Yes — sun-ray (UV) yellowing is the most common defect riders see on carbon fiber fairings. The clear coat ambers and clouds with UV exposure, and on standard OEM-style clear coat that degradation typically begins after roughly 1,000 hours of UV exposure. This is the first thing to check when deciding where to buy.
Bestem applies a proprietary UV-resistant clear coat engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV resistance — about 3× longer than standard OEM coating. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. On a naked bike like the Speed Triple S, where every carbon piece sits in direct sun with no fairing to shield it, that protection is doing real work.
Which carbon fiber parts are available for the Triumph Speed Triple S?
One in-stock example is the Triumph Speed Triple Carbon Fiber Front Fender Side Cover (SKU CBTR-SP11-FFDS), fitting 2011–2018 Speed Triple models including the 2016–2018 Speed Triple S and R. Like the rest of the Bestem line, it is pre-preg Toray carbon, autoclave-cured, and finished with the UV-resistant clear coat — a direct swap for the stock plastic piece that cuts weight at the front of the bike and sharpens the fender profile.

Why buy direct from the manufacturer instead of a marketplace?
Marketplace listings rarely disclose how a part was made, and carbon fiber quality is invisible in a product photo. Two parts can look identical online and differ completely in laminate weight, void content, and clear-coat durability. Buying from a manufacturer with a 20-year track record removes that guesswork:
- Manufacturing since 2005 — more than 20 years of carbon fiber production experience.
- OEM supplier — Bestem builds OEM carbon parts for car and motorcycle manufacturers, a level of B2B scrutiny most aftermarket-only brands never face.
- Standing warranty on the #1 failure mode — lifetime coverage against UV yellowing, stated plainly.
- Customer satisfaction as the top business priority — supported by live phone support every business day.
