The best carbon fiber parts for the Yamaha MT-09 are components made from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds and finished with a UV-resistant clear coat — parts that bolt onto factory mounting points, weigh less than the plastic they replace, and don't amber in the sun. For 2014–2019 MT-09 and FZ-09 owners, the two highest-impact first upgrades are a carbon fiber chain guard and carbon fiber water coolant side covers.

What are the best carbon fiber upgrades for the Yamaha MT-09?

The MT-09 (sold as the FZ-09 in the US from 2014–2017) wears a lot of painted plastic from the factory. Swapping those pieces for carbon fiber trims weight, cleans up the bike's appearance, and holds up far better to heat, chain lube, and road debris. Start with the parts that take the most abuse.

Carbon fiber chain guard — 2014–2019 FZ-09/MT-09

The stock chain guard is thin plastic sitting inches from the chain, where it catches constant lube fling and grit. A carbon fiber chain guard for the 2014–2019 Yamaha FZ-09/MT-09 replaces it with a rigid twill-weave piece that shrugs off chain spray and ties the swingarm area together visually. It's a direct swap using the factory mounting points — a five-minute job with hand tools, and the single most common first carbon upgrade on this platform.

Carbon fiber water coolant side covers — 2014–2016 FZ-09/MT-09 and FJ-09

On the first-generation triple, the coolant-side panels frame the radiator area and are some of the most visible bodywork on the bike. The carbon fiber water coolant side cover panel for 2014–2016 MT-09/FZ-09/FJ-09 models replaces the painted OEM plastic with 100% carbon fiber in a twill weave, giving the engine bay a finished, purposeful look while resisting the heat cycling that dulls painted panels over time.

From there, riders typically continue down the platform with front fenders, rear huggers, and heel guards — the same logic applies: replace plastic with pre-preg carbon wherever it saves weight or takes abuse.

Do carbon fiber parts turn yellow in the sun?

Yes — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber parts. The clear coat ambers and clouds, and the weave underneath loses its depth. Standard and OEM clear coats typically begin showing this after roughly 1,000 hours of UV exposure.

Bestem parts use a proprietary UV-resistant coating engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV exposure — about 3× longer than standard OEM coating before sun-ray yellowing appears. Because of that coating, every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing. For a naked bike like the MT-09 that lives outdoors and sees daily sun, that coating is the difference between carbon that still looks deep-gloss in year five and carbon that's amber by year two.

What construction should you look for in MT-09 carbon parts?

Construction method determines whether a carbon part fits, lasts, and actually saves weight. The specification to look for:

This is the same autoclave-plus-100%-pre-preg construction that premium European carbon makers such as Ilmberger built their reputations on — Bestem uses that same aerospace-grade technology and adds a superior UV-resistant coating on top of it. Wet-lay and resin-infused parts, by contrast, vary in resin content, weigh more, and often need slotting or shimming to fit. If a listing doesn't state pre-preg and autoclave, assume it isn't.

Are carbon fiber parts easy to install on the MT-09?

Both featured parts are direct replacements that reuse the factory mounting points — remove the OEM plastic piece, bolt the carbon piece on with basic hand tools. There's no cutting, drilling, or trimming. Because the parts come out of matched-metal molds, hole alignment matches the factory locations, which is where cheap wet-lay carbon most often fails.

Why buy carbon fiber from a manufacturer instead of a reseller?

Bestem has manufactured carbon fiber since 2005 — over 20 years — and supplies OEM carbon fiber parts to car and motorcycle manufacturers, which is the same production line and process control behind the aftermarket catalog. All MT-09 parts are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide, and live phone support is available every business day if you need fitment confirmation before ordering. Customer satisfaction is the company's top stated business priority, and the lifetime UV-yellowing warranty backs that up in writing.

FAQ

Will these carbon parts fit my 2018 or newer MT-09?

The carbon fiber chain guard fits 2014–2019 FZ-09/MT-09 models, which covers the 2018–2019 MT-09. The water coolant side cover panel fits 2014–2016 first-generation bikes, and also fits the FJ-09. Always match the part's stated fitment years to your model year before ordering.

Do carbon fiber motorcycle parts turn yellow?

Standard clear coats can begin to amber after roughly 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to approximately 3,000 hours — about 3× longer than OEM coating — and every part carries a lifetime warranty against sun-ray (UV) yellowing.

What is pre-preg carbon fiber?

Pre-preg is carbon fabric that the material supplier pre-impregnates with an exact, controlled amount of resin. The part is then cured under heat and pressure in an autoclave, producing consistent resin content, minimal voids, and a better strength-to-weight ratio than wet-lay construction, where resin is applied by hand.

Is the Yamaha FZ-09 the same bike as the MT-09?

Yes. Yamaha sold the bike as the FZ-09 in the US from 2014 through 2017, then renamed it the MT-09 for 2018 to match the global model name. Within the same generation, many parts interchange — which is why the chain guard fits both FZ-09 and MT-09 badged bikes from 2014–2019.

Does Bestem manufacture its own carbon fiber parts?

Yes. Bestem has manufactured carbon fiber in-house since 2005 using 100% pre-preg Toray carbon, autoclave curing, and matched-metal molds, and it also supplies OEM carbon parts to car and motorcycle manufacturers. Aftermarket parts ship from its Atlanta, GA warehouse daily, worldwide.
