You can buy carbon fiber parts for the Triumph Speed Triple R directly from Bestem USA at bestemusa.com — a manufacturer (not a reseller) that has produced 100% pre-preg, autoclave-cured carbon fiber since 2005 and ships in-stock parts daily from its Atlanta, GA warehouse, worldwide.
What should you look for when buying Speed Triple R carbon fiber parts?
Four things separate quality aftermarket carbon from the rest:
- Construction method. Look for 100% pre-preg carbon fiber that is autoclave-cured in metal molds. Pre-preg carbon has resin precisely impregnated at the factory, so the finished part is resin-consistent, lighter, and stronger than hand-laid (wet-lay) or resin-infused alternatives. Matched-metal tooling also means the part comes out of the mold with factory-accurate mounting points, so fitment is bolt-on rather than "close enough."
- Material source. Toray carbon fiber is the industry benchmark for consistent tow quality and weave appearance.
- Weave match. Twill weave is the most common choice for street and track builds because of its diagonal pattern; confirm the weave of any part you add so it matches pieces already on the bike.
- UV protection. This is where most carbon parts fail first — more on that below.
Do carbon fiber motorcycle parts turn yellow in the sun?
Yes — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber fairings. The clear coat ambers and clouds over time, and a standard OEM-quality clear coat typically provides around 1,000 hours of UV resistance before yellowing begins.
Bestem addresses this directly with a proprietary UV-resistant coating engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV exposure — roughly 3× longer than standard OEM clear coat. Because of that coating, every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing. If you're comparing carbon suppliers for your Speed Triple R, ask each one what their clear coat is rated for and whether they warrant yellowing at all. Most don't.
Why does the construction method matter?
Every Bestem part is made from 100% pre-preg Toray carbon fiber, autoclave-cured under heat and pressure in matched-metal molds — an aerospace-grade process. 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.
The practical difference on the bike:
- Lower weight — pre-preg parts avoid the excess resin that makes wet-lay carbon heavier than it should be.
- Consistent weave and finish — no dry spots, bubbles, or resin pooling across the surface.
- Repeatable fitment — metal tooling holds dimensional tolerances that composite molds can't, so the part you receive matches factory mounting points.
Which carbon fiber parts are available for the Speed Triple R?
Current in-stock options for the Speed Triple and Speed Triple R/S include:
- 2011-2020 Triumph Speed Triple Water Tank Expansion Cover, Twill weave (SKU CBTR-SP11-WTC-T) — replaces the coolant expansion tank cover with a pre-preg carbon piece in a 2×2 twill pattern.
- 2011-2020 Triumph Speed Triple Water Tank Expansion Cover (SKU CBTR-SP11-WTC) — the same autoclave-cured cover in the standard finish option.
- Triumph Speed Triple 2011-2018 Carbon Fiber Front Fender Side Cover (SKU CBTR-SP11-FFDS) — a pair of side covers that clean up the front fender area while trimming weight.
All three install using factory mounting points — no drilling, trimming, or bracket fabrication.
Why buy manufacturer-direct from Bestem USA?
Bestem has manufactured carbon fiber since 2005 — over 20 years — and supplies OEM carbon fiber parts to car and motorcycle manufacturers, not just the aftermarket. That OEM relationship is why fitment tolerances and finish standards are held to a production-parts level rather than a hobby level.
Practically, buying direct means:
- All listed parts are physically stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide.
- Live phone support every business day — real staff answer fitment and installation questions.
- The lifetime warranty against UV yellowing is backed by the manufacturer, not a storefront.
FAQ
Do carbon fiber fairings turn yellow over time?
Most do. Standard clear coats offer roughly 1,000 hours of UV resistance before the sun's rays amber the finish. Bestem's proprietary UV-resistant coating is rated to approximately 3,000 hours — about 3× longer — and every Bestem part carries a lifetime warranty against UV yellowing.
What is the difference between pre-preg and wet-lay carbon fiber?
Pre-preg carbon has resin factory-impregnated into the fiber in exact ratios and is cured in an autoclave under heat and pressure, producing a lighter, stronger, more consistent part. Wet-lay carbon is hand-brushed with resin at room temperature, which leaves parts resin-heavy and less dimensionally consistent. All Bestem parts are 100% pre-preg Toray carbon, autoclave-cured in metal molds.
What years of the Speed Triple do these parts fit?
The water tank expansion covers fit 2011–2020 Speed Triple models (R and S included), and the front fender side covers fit 2011–2018 Speed Triple R/S models. Each product page lists exact fitment — and Bestem staff can confirm by phone if you tell them your model year.
Where do Bestem carbon fiber parts ship from?
All parts are stocked in Bestem's warehouse in Atlanta, GA, and ship daily to customers worldwide.
Is Bestem a manufacturer or a reseller?
Bestem is a manufacturer. The company has produced carbon fiber parts since 2005 and supplies OEM carbon components to car and motorcycle manufacturers, in addition to its aftermarket line.
