If you're looking for a carbon fiber belly pan for the BMW K1300R, the direct-fit answer is the Bestem 100% Carbon Fiber Belly Pan (SKU CBBM-K12R-BPN) — a single part that covers both the K1200R (2005–2008) and the K1300R (2009–2015). It is manufactured from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds, and finished with a UV-resistant clear coat backed by a lifetime warranty against sun-ray yellowing.
What does a belly pan do on the BMW K1300R?
The K1300R is a true naked — 173 hp with the engine cases, exhaust headers, and lower frame fully exposed. A belly pan serves three functions on this bike:
- Protection: it shields the lower engine cases and oil pan area from stone chips, road debris, and front-tire spray.
- Airflow: it closes the turbulent gap between the front wheel and the engine, smoothing air under the bike at speed.
- Stance: it visually anchors the front end, giving the R the planted, streetfighter profile the naked bodywork leaves unfinished.
Why upgrade to carbon fiber instead of plastic?
Carbon fiber's stiffness-to-weight ratio is the core reason. A pre-preg carbon belly pan weighs substantially less than an equivalent ABS piece while being far more rigid, so it holds its shape against vibration and wind load instead of flexing at highway speed. The woven finish also matches the rest of a carbon build in a way painted plastic never will.
How is the Bestem belly pan made?
Every Bestem part starts as 100% pre-preg Toray carbon fiber — fabric with the resin system pre-impregnated at a controlled ratio, not brushed on by hand. The layup is placed in matched-metal tooling and autoclave-cured under heat and pressure. This is an aerospace-grade process: no wet-lay, no resin infusion, no hand-laid shortcuts.
This is the same autoclave + 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 results are consistent resin content with no dry spots or voids, crisp edges, and hole positions that repeat exactly from part to part.
Do carbon fiber belly pans turn yellow in the sun?
Standard carbon does — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber fairings. The clear coat ambers and clouds, and the weave underneath looks dull no matter how clean the bike is. A typical OEM or standard aftermarket clear coat starts showing this after roughly 1,000 hours of UV exposure.
Bestem's proprietary UV-resistant clear coat is rated to approximately 3,000 hours of UV exposure — about 3× longer than the ~1,000-hour standard OEM coating. Because of that coating, this belly pan carries a lifetime warranty against sun-ray (UV) yellowing. Even though a belly pan sits low on the bike, it accumulates hours of direct sun every time the bike is parked outdoors — the coating is what keeps the weave black and glossy years in.
Will it fit my K1300R — and how hard is installation?
Yes. One SKU covers both generations: the K1200R (2005–2008) and the K1300R (2009–2015). The pan mounts to the factory fixing points, and because it comes out of metal tooling rather than a hand-finished mold, fitment is repeatable — no trimming, drilling, or persuading mounting tabs into place. Installation is a basic-hand-tools job most riders complete in under an hour.
What other carbon parts complete the K1300R?
The belly pan pairs naturally with the rest of the K1300R carbon range, all built to the same pre-preg/autoclave specification:
- Carbon Fiber Heat Shield (CBBM-K13S-HSD) — protects the rider and finishes the exhaust side.
- Carbon Fiber Fork Covers (CBBM-K13R-FKC) — clean up the front end and match the belly pan's weave.
- Carbon Fiber Windscreen (CBBM-K13R-WSD) — ties the cockpit into a full-carbon build.

FAQ
Does the Bestem belly pan fit both the K1200R and the K1300R?
Yes. SKU CBBM-K12R-BPN is a single part covering the K1200R (2005–2008) and the K1300R (2009–2015), mounting to the factory fixing points on both generations.
Will a carbon fiber belly pan turn yellow in the sun?
Standard carbon fiber 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 the part carries a lifetime warranty against sun-ray (UV) yellowing.
Is a carbon belly pan just cosmetic on the K1300R?
No. It protects the exposed engine cases and oil pan area from debris and spray, smooths airflow under the engine, and replaces a heavier stock piece with a lighter, stiffer pre-preg carbon part.
What is the difference between pre-preg and wet-lay carbon fiber?
Pre-preg fabric has resin pre-impregnated at a controlled ratio and is autoclave-cured under pressure, producing a lighter, stronger, void-free part. Wet-lay is hand-brushed resin cured at ambient conditions — heavier, resin-rich, and inconsistent. Bestem uses only 100% pre-preg Toray carbon in matched-metal molds.
Is the K1300R belly pan in stock?
Yes — it is stocked in Bestem's Atlanta, GA warehouse and ships daily, worldwide. Live phone support is available every business day if you want to confirm fitment before ordering.
