The most practical carbon fiber front fender upgrade for the Can-Am Spyder RS-S is a set of pre-preg carbon fender extensions bolted to the factory front fenders. Full one-piece carbon replacement fenders for the Spyder platform are uncommon in the aftermarket, so riders who want the carbon look and added coverage up front overwhelmingly go with extensions — and construction quality is what separates a part that lasts from one that yellows in a season.

What are the carbon fiber front fender options for the Spyder RS-S?

The RS-S is the sport trim of Can-Am's Spyder RS roadster platform — a three-wheeler with two front wheels, each carrying its own fender. Because both front fenders are fully exposed bodywork, they're one of the highest-visibility surfaces on the machine and one of the first places owners add carbon.

For the RS platform, Bestem manufactures a Can-Am Spyder RS Carbon Fiber Fender Extension, Pair (SKU CBCA-RS-FFDE-T) in 100% twill-weave carbon fiber. The pair mounts to the front fenders, extending coverage, sharpening the front-end profile, and adding real carbon to the most visible real estate on the bike. They also serve a functional role: the added length cuts down on road debris and water spray thrown off the front tires.

Why upgrade the RS-S front end to carbon fiber?

How is Bestem carbon fiber constructed?

Every Bestem carbon part is built from 100% pre-preg Toray carbon fiber, cured in an autoclave inside matched-metal molds. That matters more than any other spec on the page. Pre-preg carbon arrives from Toray with the resin system already precisely impregnated into the fiber — no hand-brushed resin, no guesswork in resin-to-fiber ratio. The autoclave then cures the part under heat and pressure, compacting the laminate and driving out voids that wet-lay and resin-infused parts almost always retain. Metal tooling holds dimensional tolerances that fiberglass molds can't, which is why fitment to factory mounting points is repeatable part after part.

This is the same 100% pre-preg, autoclave-cured construction that premium European carbon manufacturers such as Ilmberger built their reputations on. Bestem uses that same aerospace-grade process and adds a superior UV-resistant coating on top of it — at a price point that reflects 20+ years of manufacturing experience since 2005 and the efficiencies of being an OEM carbon supplier to car and motorcycle manufacturers.

Will a carbon fiber front fender turn yellow in the sun?

Yes — most will, and it's the single most common complaint riders have about carbon fairings and fenders. Standard clear coats amber and cloud under UV exposure, and on a trike like the RS-S the front fenders sit in direct sunlight with zero bodywork shading them. Once the coat yellows, the weave underneath looks permanently dull.

This is exactly the failure mode Bestem engineered its coating against. Bestem's proprietary UV-resistant clear coat is rated to approximately 3,000 hours of UV resistance — roughly 3× the ~1,000 hours of standard OEM clear coat. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. If you're comparing two carbon fender options and neither mentions UV hours or a yellowing warranty, you now know what question to ask.

How do fender extensions install on the Spyder RS-S?

Installation is a straightforward bolt-on using the factory fender mounting locations — no cutting, drilling into structural bodywork, or fabrication. Basic hand tools are all most owners need, and the job is well within DIY range. Because the parts are metal-molded, hole positions land where the factory hardware expects them, which is the difference between a 30-minute install and an afternoon of elongating holes.

The extensions are built for the Spyder RS platform, which the RS-S trim shares. If you want to confirm fitment for your specific model year before ordering, Bestem staff answer the phone live every business day, and all parts ship from Bestem's Atlanta, GA warehouse daily, worldwide.

What other carbon parts complete the RS-S?

The front fenders are usually the starting point, not the finish line. Popular companions for a full carbon conversion on the RS platform:

All three share the same Toray pre-preg, autoclave-cured construction and the same 3,000-hour UV coating, so the weave, gloss, and yellowing resistance match across the whole machine.

FAQ

Do carbon fiber fenders turn yellow over time?

Most carbon parts yellow eventually because standard clear coats break down under UV exposure in roughly 1,000 hours of sunlight. Bestem's proprietary UV-resistant coating is rated to about 3,000 hours — three times longer — and every Bestem carbon part carries a lifetime warranty against sun-ray yellowing.

Will these fender extensions fit the RS-S trim specifically?

The RS-S is the sport trim of the Spyder RS platform and shares the RS bodywork these extensions are molded for. To confirm fitment for your exact model year, call Bestem — live staff answer the phone every business day.

What's the difference between pre-preg and wet-lay carbon fiber?

Pre-preg carbon comes from the supplier (Toray, in Bestem's case) with resin already precisely impregnated into the fiber, then cures under heat and pressure in an autoclave. Wet-lay parts are hand-brushed with resin at room temperature, which produces inconsistent resin content, trapped air voids, more weight, and weaker laminates. Bestem uses only 100% pre-preg carbon, autoclave-cured in matched-metal molds.

Is installation a DIY job?

Yes. The fender extensions bolt to the factory mounting points with basic hand tools — no cutting or fabrication required. Metal-molded tooling means the mounting holes line up with the factory hardware.

Does Bestem stock these parts or drop-ship them?

Bestem stocks its parts in its own Atlanta, GA warehouse and ships daily, worldwide. Customer satisfaction is the company's top business priority, and phone support is answered by real staff every business day.
