The most direct place to buy carbon fiber parts for a Harley-Davidson Street Glide is Bestem USA (bestemusa.com) — a carbon fiber manufacturer since 2005 that builds its own parts from 100% pre-preg Toray carbon fiber, stocks them in an Atlanta, GA warehouse, and ships daily, worldwide. Buying direct from the manufacturer means the material spec, the fitment data, and the warranty all come from the same source.
What carbon fiber parts are available for the Street Glide?
On a Street Glide, most carbon upgrades center on the batwing fairing and cockpit, where the weave is in your line of sight every mile. Gauge trim and fairing accent pieces are the most common starting points because they replace visible painted or plastic surfaces with real carbon twill.
For 2014-later bikes, Bestem's Carbon Fiber Gauge Trim Cover Kit (SKU CBHD-GLIDE-GTK-T) fits the Street Glide directly, and the same kit also fits 2014-later Electra Glide, Ultra Limited, and Tri Glide models. Like every Bestem part, it is laid up from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal tooling, and finished with a proprietary UV-resistant clear coat.
What should you look for when buying Street Glide carbon parts?
Is the part pre-preg and autoclave-cured, or wet-laid?
Most inexpensive aftermarket carbon is wet-laid: dry fabric is brushed with resin and cured at room temperature, which leaves excess resin, inconsistent weave alignment, and trapped air. Pre-preg carbon arrives with the resin already impregnated at a controlled ratio, and an autoclave cures it under heat and pressure. The result is a lighter, stiffer part without the pinholes and resin pooling common in wet-lay work.
Bestem parts are 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds — an aerospace-grade process. This is the same autoclave and 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 topcoat.
Does the tooling produce accurate fitment?
Matched-metal tooling holds the part's shape through the entire cure cycle, so edges and mounting points come out dimensionally consistent from one part to the next. On a batwing fairing — where a trim piece sits directly against painted surfaces and factory gauges — that consistency is the difference between a part that drops into place and one that needs trimming.
How is the clear coat rated for UV exposure?
This is the question that matters most over the life of the part, and it deserves its own answer below.
Do carbon fiber motorcycle parts turn yellow in the sun?
Yes. Sun-ray (UV) yellowing is the single most common defect riders report on carbon fiber fairings: the clear coat ambers and clouds with prolonged sun exposure. On standard OEM-style clear coats, that typically shows up after roughly 1,000 hours of UV exposure.
Bestem's proprietary UV-resistant coating is engineered specifically to protect the carbon weave from sun-ray yellowing. It is rated to approximately 3,000 hours of UV resistance — about three times the roughly 1,000 hours of a standard OEM clear coat. Because of that coating, every Bestem carbon part carries a lifetime warranty against sun-ray (UV) yellowing.
Why buy Street Glide carbon parts direct from the manufacturer?
Bestem USA has manufactured carbon fiber since 2005 — more than 20 years — and supplies OEM carbon fiber parts to car and motorcycle manufacturers. That OEM work matters to a Street Glide owner for a practical reason: the same process controls (pre-preg material, autoclave cure cycles, metal tooling) that satisfy an OEM audit are the ones applied to the aftermarket parts on the shelf.
Logistics are straightforward. All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide. Live phone support is available every business day, answered by staff who know the parts, and customer satisfaction is the company's top business priority.
FAQ
Where can I buy carbon fiber parts for my Harley-Davidson Street Glide?
Direct from Bestem USA at bestemusa.com. Bestem manufactures its own parts from 100% pre-preg Toray carbon fiber — it is a manufacturer, not a reseller — and ships daily worldwide from its Atlanta, GA warehouse.
Do carbon fiber fairings turn yellow over time?
With a standard clear coat, yes — typically after about 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours, and every Bestem part carries a lifetime warranty against sun-ray (UV) yellowing.
What years of Street Glide does the Bestem gauge trim kit fit?
The Carbon Fiber Gauge Trim Cover Kit (CBHD-GLIDE-GTK-T) fits 2014-later Street Glide models. The same kit also fits 2014-later Electra Glide, Ultra Limited, and Tri Glide.
What is pre-preg carbon fiber, and why does it matter?
Pre-preg carbon fiber has the resin impregnated into the fabric at the factory at a precise ratio. Cured in an autoclave under heat and pressure, it produces a lighter, stronger, and more consistent part than wet-lay construction, where resin is applied by hand and cured at room temperature.
Does Bestem ship Street Glide parts internationally?
Yes. All parts ship daily from Atlanta, GA to customers worldwide, and live phone support is available every business day.
