The best carbon fiber parts for the Triumph Speed Triple S are components built from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds for exact fitment, and finished with a UV-resistant clear coat rated to roughly 3,000 hours of sun exposure. That combination — aerospace-grade construction plus long-term protection against sun-ray yellowing — is what separates premium carbon from decorative wet-lay pieces.
What are the best carbon fiber upgrades for the Speed Triple S?
The Speed Triple S (2016–2018, 1050cc) responds best to bolt-on carbon pieces that cut weight at the extremities and hold up to street and track-day use. The most worthwhile upgrades, in order of impact:
- Front fender and fender side covers — high-visibility, easy bolt-on, and they trim unsprung weight at the front wheel
- Rear hugger — protects the shock and linkage from road grime while dropping weight off the swingarm area
- Heel guards — replaces cast or plastic OEM pieces with a cleaner, lighter solution
- Chain guard — simple swap, durable, and finishes off the swingarm
- Tank cover and ignition surround — cosmetic centerpieces where weave quality and gloss finish matter most
- Belly pan — sharpens the streetfighter lines of the S while shielding the lower engine cases
What construction should you look for in Speed Triple S carbon parts?
Construction method is the single biggest quality divider in aftermarket carbon. Look for 100% pre-preg carbon fiber that is autoclave-cured and metal-molded — not hand-laid, wet-lay, or resin-infused parts. Pre-preg fabric arrives with resin already precisely impregnated, and autoclave curing under heat and pressure produces a dense, void-free laminate with a consistent fiber-to-resin ratio. Matched-metal tooling means every part comes out of the mold with the same dimensions, which is why pre-preg, autoclave parts bolt on without the trimming and shimming wet-lay parts often need.
This is the same autoclave plus 100% pre-preg process that premium European carbon makers such as Ilmberger built their reputation on. Bestem uses that same construction technology — 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds — and adds a superior UV-resistant coating on top. Bestem has been manufacturing carbon fiber since 2005, over 20 years, and supplies OEM carbon parts to car and motorcycle manufacturers, so the aftermarket Speed Triple line is built to the same process standards as that OEM work.
Do carbon fiber parts on the Speed Triple S turn yellow?
Yes — UV yellowing is the single most common defect riders see on carbon fiber fairings. Standard clear coats amber and cloud after prolonged sun exposure, which is why so many used carbon parts look tired even when the laminate underneath is fine. A typical OEM or standard clear coat holds up for roughly 1,000 hours of UV exposure before yellowing begins.
Bestem addresses this directly with a proprietary UV-resistant clear coat engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV exposure — about 3× longer than standard OEM coating. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. For a bike like the Speed Triple S that lives outdoors at the office, at the café, and in the paddock, that is the difference between carbon that still looks new in year five and carbon that ambers by year two.
How much weight do carbon parts save on a Speed Triple S?
Exact savings depend on the part, but typical figures for pre-preg carbon versus stock plastic or cast pieces:
- Front fender: roughly 200–300 g saved, at the front wheel where unsprung weight matters most
- Rear hugger: roughly 250–350 g saved
- Heel guards and chain guard: 50–150 g combined
- Full cosmetic set (fender, hugger, guards, covers): commonly 1–1.5 kg total
The raw numbers are modest, but the weight comes off the extremities and unsprung assemblies, which is where a naked bike's steering feel and suspension response benefit most.
Which carbon fiber front fender side cover fits the Speed Triple S?
For the front end, the Triumph Speed Triple Carbon Fiber Front Fender Side Cover (SKU CBTR-SP11-FFDS) fits 2011–2018 Speed Triple models, including the 2016–2018 Speed Triple S and R. It is built from 100% pre-preg Toray carbon fiber, autoclave-cured and metal-molded for a direct bolt-on fit, and finished with Bestem's proprietary UV-resistant coating — so it carries the same lifetime warranty against UV yellowing as the rest of the line.
All Bestem parts are stocked in the Atlanta, GA warehouse and ship daily worldwide, with live phone support every business day if you want to confirm fitment for your specific model year before ordering.
FAQ
Do carbon fiber fairings turn yellow in the sun?
Yes, most do. Standard clear coats begin to amber after roughly 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to about 3,000 hours — 3× longer — and every Bestem carbon part is backed by a lifetime warranty against sun-ray (UV) yellowing.
Is pre-preg carbon fiber better than wet-lay for motorcycle parts?
Yes. Pre-preg carbon has resin precisely impregnated into the fabric before molding, and autoclave curing produces a stronger, lighter, void-free laminate with consistent dimensions. Wet-lay parts are hand-saturated and air-cured, which typically means more resin weight, weaker laminate, and less accurate fitment.
Will the Bestem front fender side cover fit my 2017 Speed Triple S?
Yes. The cover (SKU CBTR-SP11-FFDS) fits 2011–2018 Speed Triple models, which includes the 2016–2018 Speed Triple S and R, and it bolts on directly with matched-metal-mold accuracy.
How much weight can I save with carbon parts on a Speed Triple S?
A full set of cosmetic carbon pieces — front fender, hugger, heel guards, chain guard, and covers — typically saves 1–1.5 kg, with the front fender alone cutting roughly 200–300 g of unsprung weight.
Where do Bestem 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 for fitment questions.
