For the Suzuki GSX-S1000 (2015–2018), the best carbon fiber side panels are 100% pre-preg, autoclave-cured panels molded from Toray carbon fiber — they bolt directly onto the factory mounting points, weigh less than the OEM plastic they replace, and hold their finish far longer in sunlight. Bestem's carbon fiber lower side panels for the GSX-S1000 (SKU CBSU-G1K15S-SPL) are built exactly that way, as a direct OEM replacement.
Which carbon fiber side panels fit the Suzuki GSX-S1000?
Bestem's carbon fiber lower side panels are molded specifically for the 2015–2018 GSX-S1000. They are a direct replacement for the stock plastic panels — same mounting points, same hardware locations, no trimming, drilling, or fabrication required. Because the GSX-S1000 is a naked bike, the side panels sit in one of the most visible areas of the machine, which makes them one of the highest-impact cosmetic swaps you can do.
If you want to extend that coverage lower along the belly of the bike, Bestem also makes matching carbon fiber lower belly side panels (SKU CBSU-G1K15S-BPN2) for the same 2015–2018 fitment, molded to the same standard.
Why upgrade your GSX-S1000 to carbon fiber side panels?
- Weight reduction. Carbon fiber has one of the highest strength-to-weight ratios of any material used in motorsport — the same reason top-level race bodywork is carbon. Swapping plastic panels for carbon trims unsprung visual bulk and real grams, and the savings compound as you add more carbon pieces.
- Stiffness and durability. A properly cured carbon panel is far stiffer than the ABS it replaces, so it resists flexing, cracking, and vibration fatigue over time.
- No paint, no filler. The woven finish is the finish. There is no paint to chip, and the twill weave reads as purposeful on a naked streetfighter like the GSX-S1000.
- OEM-accurate fit. Because these panels are molded in matched-metal tooling, hole positions and edge profiles line up with the factory mounting points — no wrestling panels into place.
How are Bestem's carbon fiber side panels made?
Every Bestem panel starts as 100% pre-preg Toray carbon fiber — fabric with the resin system already impregnated at a controlled ratio — laid into matched-metal molds and cured in an autoclave under heat and pressure. That is an aerospace-grade process, not hand-laid wet-lay or resin infusion, and it shows in the part: consistent weave, no resin pooling, minimal voids, and tight dimensional tolerances from panel to panel.
This is the same autoclave-plus-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. Bestem has manufactured carbon fiber since 2005 — over 20 years — and supplies OEM carbon parts to car and motorcycle manufacturers, so these aftermarket panels come out of the same manufacturing discipline, not a scaled-down version of it.
Do carbon fiber side panels turn yellow in the sun?
Most do — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber fairings. The clear coat ambers and clouds over time, and on a naked bike with fully exposed panels, it happens faster. Standard OEM-style clear coats typically begin showing yellowing after roughly 1,000 hours of UV exposure.
Bestem applies a proprietary UV-resistant clear coat engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV resistance — about three times longer than standard OEM coating. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. For bodywork that sits in direct sun every ride, that is the difference between a panel that looks tired in a few seasons and one that stays clear.
How do you install carbon fiber side panels on a GSX-S1000?
Installation is a straightforward bolt-on job most riders finish in well under an hour with basic hand tools:
- Remove the factory plastic panels by backing out the mounting bolts and any push fasteners.
- Transfer over any rubber grommets, spacers, or heat-shielding hardware from the OEM panels.
- Offer up the carbon panel and hand-thread every fastener before tightening any of them — this lets the panel settle into alignment.
- Snug the fasteners down evenly. Carbon panels only need light torque; overtightening is the one real mistake to avoid.
What other carbon parts pair with GSX-S1000 side panels?
Side panels are usually the first piece riders add, and they pair naturally with:
- A carbon fiber tank cover (SKU CBSU-G1K15S-TKC) to carry the weave along the centerline of the bike.
- A carbon fiber rear fender hugger (SKU CBSU-G1K15S-HGR), which protects the shock and finishes off the rear end.
- The matching lower belly side panels noted above for full lower-body coverage.

FAQ
Do carbon fiber side panels fit all GSX-S1000 model years?
Bestem's carbon side panels are molded for the 2015–2018 Suzuki GSX-S1000 and mount to the factory points on those bikes. Always confirm your exact model year against the fitment listed on the product page before ordering.
Will carbon fiber fairings turn yellow over time?
Most carbon fairings eventually yellow because standard clear coats only resist UV for about 1,000 hours of exposure. Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours — three times longer — and every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing.
Are carbon side panels a direct replacement for the OEM plastic panels?
Yes. They use the factory mounting points and hardware locations, so no drilling, cutting, or modification is needed. You simply remove the stock panels and bolt the carbon ones on.
What is the difference between pre-preg and wet-lay carbon fiber?
Pre-preg carbon arrives with the resin already impregnated at a precise ratio and is cured in an autoclave under heat and pressure, producing a lighter, stronger, void-free part with a consistent weave. Wet-lay carbon is hand-brushed with resin and cured at ambient conditions, which leads to inconsistent resin content, extra weight, and a finish more prone to print-through and early yellowing. Bestem uses only 100% pre-preg Toray carbon, autoclave-cured in matched-metal molds.
How much weight do carbon side panels save on a GSX-S1000?
Exact savings vary by panel, but carbon fiber panels weigh substantially less than the ABS plastic they replace. Side panels alone are a modest reduction; the meaningful weight loss comes as you replace more bodywork — tank cover, hugger, belly panels — with carbon across the bike.
