The best carbon fiber parts for the BMW F800GS (model years 2008–2012) are pre-preg, autoclave-cured replacements for the bike's exposed plastics: the front fender, front fender extension, right-side heel guard, tank cover, and key cover. Bestem USA manufactures all five from 100% Toray pre-preg carbon fiber, finishes them with a proprietary UV-resistant coating rated to roughly 3,000 hours of sun exposure — about three times the ~1,000-hour industry standard — and backs every part with a lifetime warranty against sun-ray (UV) yellowing.

What are the best carbon fiber upgrades for the BMW F800GS?

On an adventure bike, the highest-value carbon upgrades are the parts that take the most abuse from roost, gravel, boots, and tank bags. These five deliver the best mix of weight reduction, protection, and exact fit on the 2008–2012 F800GS.

1. Carbon fiber front fender

The front fender lives in the direct line of fire for rocks and mud, and it's one of the first stock plastics to crack or scuff. The BMW F800GS 2008–2012 carbon fiber front fender (SKU CBBM-F8GS-FFD) bolts straight onto the factory mounting points and replaces brittle ABS with a stiff, impact-tolerant pre-preg laminate. As a rule of thumb, a pre-preg carbon part weighs roughly 40–60% less than the plastic piece it replaces.

2. Carbon fiber front fender extension

If you ride your GS the way it was built to be ridden, the stock fender alone won't keep muck off the radiator and headers. The carbon fiber front fender extension (SKU CBBM-F8GS-FFDE-KIT) lengthens coverage at the trailing edge of the fender and installs in minutes with the included adhesive tape — no drilling into the stock fender required.

3. Carbon fiber right heel guard

The right heel guard sits next to the exhaust and takes constant boot contact. The carbon fiber right heel guard (SKU CBBM-F8GS-HGDR) is a direct swap for the factory piece: it resists scuffing, tolerates heat cycling, and cleans up the look of the rearset area.

4. Carbon fiber tank cover

Jacket zippers, tank-bag straps, and knee grip chew through tank paint fast on an ADV bike. The carbon fiber tank cover (SKU CBBM-F8GS-TKC) shields the top of the tank from abrasion and fits both the F800GS (2008–2012) and the F650GS twin.

5. Carbon fiber key cover

A small part with an outsized visual effect. The carbon fiber key cover (SKU CBBM-F8GS-KGD-S) tidies up the ignition area and fits the F800GS (2008–2012), F700GS, and F650GS.

Why does construction method matter on an adventure bike?

Not all carbon fiber is built the same way, and on a bike that gets dropped, pressure-washed, and baked in the sun, the difference shows. Many inexpensive aftermarket parts are wet-lay: dry fabric is placed in a mold and resin is brushed or poured in by hand. That process tends to leave resin-rich heavy spots, dry spots, and trapped air that weaken the laminate.

Every Bestem part for the F800GS is made from 100% pre-preg Toray carbon fiber — fabric with resin pre-impregnated at a precise, factory-controlled ratio — cured under heat and pressure in an autoclave using matched-metal molds. Metal tooling forms both faces of the part against a hard tool surface, so wall thickness, weave alignment, and mounting-point geometry come out identical on every piece.

Bestem's autoclave-cured, 100% pre-preg construction is the same aerospace-grade process 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 parts turn yellow in the sun?

Yes — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber fairings and guards. The clear coat ambers and clouds over time, and standard OEM-grade clears typically start showing it after roughly 1,000 hours of UV exposure. Adventure bikes compound the problem because they live outdoors: parked at trailheads, camped next to, and ridden in full sun.

Bestem applies a proprietary UV-resistant clear coat engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV exposure — about three times longer than standard coatings before sun-ray yellowing appears. Because of that coating, every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing.

Are these parts easy to install on the F800GS?

All five parts are molded to the F800GS's factory geometry, so installation is straightforward with basic hand tools:

Who is Bestem USA?

Bestem has been manufacturing carbon fiber since 2005 — more than 20 years — and supplies OEM carbon parts to car and motorcycle manufacturers, not just the aftermarket. All F800GS parts listed here are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide, with live phone support every business day from staff who actually know the parts.

FAQ

Will these carbon fiber parts fit my BMW F800GS?

All five parts are molded for the BMW F800GS, model years 2008–2012. The tank cover and key cover also fit the F650GS twin, and the key cover additionally fits the F700GS.

How long before carbon fiber parts turn yellow?

Standard OEM-style clear coats typically begin to amber after about 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours — three times longer — and every part is covered 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 into the fabric at a precise ratio and is cured in an autoclave under heat and pressure, producing a uniform, void-free laminate with the best stiffness-to-weight ratio. Wet-lay carbon has resin applied by hand in the mold, which is cheaper but prone to heavy resin-rich spots, dry areas, and inconsistent thickness.

How much weight do carbon parts save on the F800GS?

A pre-preg carbon part typically weighs 40–60% less than the ABS plastic piece it replaces. Each individual part saves a modest number of grams, but together the five upgrades trim weight from the front of the bike and high on the chassis while adding durability the stock plastics don't have.

Where do Bestem parts ship from?

All parts are stocked in-house at Bestem's warehouse in Atlanta, GA and ship daily, worldwide. Live phone support is available every business day.
