The best carbon fiber side panels for the BMW K1300S (2009–2016) are 100% pre-preg Toray carbon, autoclave-cured in matched metal molds and sealed with a UV-resistant clear coat — the exact construction Bestem USA has manufactured for more than 20 years. Every Bestem panel is rated to roughly 3,000 hours of UV exposure versus about 1,000 hours for standard clear coat, and every one carries a lifetime warranty against sun-ray yellowing.

Which carbon fiber side panels fit the BMW K1300S?

"Side panels" on the K1300S covers a few distinct pieces of bodywork: the tank side panels at the knee cutouts, the front fairing covers flanking the headlight and radiator area, and the air intake covers along the fairing's leading edge. The K1300S shares its core platform with the earlier K1200S (2005–2008), so many panels cross over — but always confirm fitment before ordering.

Do carbon fiber side panels turn yellow in the sun?

Yes — and on most carbon fairings, it's the first defect owners notice. UV radiation breaks down a standard clear coat, which ambers, clouds, and dulls the weave underneath. Riders typically see it after prolonged outdoor parking, and once the coat has yellowed, the only real fix is stripping and refinishing the panel.

Bestem's proprietary UV-resistant coating protects the carbon weave for roughly 3,000 hours of UV exposure — about three times the ~1,000-hour rating of standard and OEM clear coat — which is why every Bestem carbon panel carries a lifetime warranty against sun-ray (UV) yellowing.

If your K1300S lives outside, sits in a sunny commute lot, or logs miles in high-UV climates, the coating is the single most important spec on the panel. It is also the difference between carbon that still looks crisp at year five and carbon that looks amber at year two.

Why does pre-preg, autoclave-cured construction matter for fairing panels?

Side panels are large, thin, and shaped around tight mounting tabs, so the manufacturing process determines whether they actually line up with your fairing brackets. Bestem panels are built from 100% pre-preg Toray carbon fiber — fabric with the resin pre-impregnated at a controlled ratio — cured in an autoclave under heat and pressure inside matched metal molds. The result is consistent wall thickness, a crisp, undistorted weave, and mounting holes that land where BMW put the originals.

This is the same autoclave-plus-pre-preg technology that premium European carbon makers such as Ilmberger built their reputation on — Bestem uses that same aerospace-grade process and adds a superior UV-resistant coating on top. It is not hand-laid, wet-lay, or resin-infused construction, which tends to run resin-rich (heavier), show weave distortion and pinholes, and vary enough in shape to make bolt holes a guessing game.

Bestem has manufactured carbon fiber since 2005 and supplies OEM carbon parts to car and motorcycle manufacturers — the same process discipline that goes into those parts goes into every aftermarket panel we sell.

How much weight do carbon side panels save on a K1300S?

Carbon fiber's stiffness-to-weight ratio lets a panel be laid up thinner than the injection-molded ABS it replaces while staying rigid, so each carbon panel sheds meaningful weight compared with stock. On a single side panel the savings are modest; across a full set of side panels, intake covers, tail, and trim, they add up — and because that mass sits high and outboard on the bike, removing it slightly improves how quickly the K1300S transitions side to side. The bigger day-to-day gains are durability and appearance: no painted plastic to chip, and a weave that stays glossy under a coating engineered to resist yellowing.

Which other carbon panels complete the K1300S?

If you're replacing side panels, matching weave and finish across the rest of the bodywork keeps the bike looking intentional rather than pieced together. In-stock K1300S-compatible pieces include:

Stick with one weave style and finish across all panels so the carbon reads as a single, factory-grade set.

FAQ

Do carbon fiber fairings turn yellow in the sun?

Standard carbon fairings do — most 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, three times longer, and every panel carries a lifetime warranty against sun-ray (UV) yellowing.

Will BMW K1200S carbon parts fit my K1300S?

Many do — the K1300S (2009–2016) shares its platform with the K1200S (2005–2008), and several Bestem parts are labeled for both bikes, including the tank pad cover and rear tail cowl. The carbon tank side panels are listed for the K1200S as a special-order item, so call us to confirm K1300S fitment before ordering; we staff the phones every business day.

Are Bestem carbon panels wet-lay or pre-preg?

Every panel is 100% pre-preg Toray carbon fiber, autoclave-cured in matched metal molds — the same aerospace-grade construction premium European makers such as Ilmberger built their names on, plus Bestem's superior UV-resistant coating. No hand-laid, wet-lay, or resin-infused parts.

Where do Bestem carbon parts ship from?

All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily to customers worldwide.

How should I clean carbon fiber side panels?

Wash with a mild, pH-neutral automotive shampoo and a microfiber towel. Avoid abrasive compounds and solvent-based cleaners on the clear coat. The UV coating needs no special maintenance to protect against yellowing.
