ABOUT UPPER CARBON

Upper Carbon is built for riders who believe a performance bagger should reflect more than horsepower alone. It should carry presence, precision, and purpose in every detail.

Founded in Winston-Salem by Big Al and strengthened by Kenny’s deep Harley performance and racing background, Upper Carbon was created to design original carbon fiber parts that stand apart in both fitment and finish. This is not mass-produced carbon. This is premium craftsmanship for serious builders.

What We Do

At Upper Carbon, we specialize in one-off and limited-production carbon fiber parts built specifically for performance bagger riders who demand more.

Every piece is:

  • Designed in-house
  • Built with premium 3K prepreg carbon fiber
  • Tested with real-world riding and racing in mind
  • Created to stand apart—not blend in

We don’t mass produce. We don’t copy. We build what others can’t.

Built Different

Our approach is simple—original design first.

While others replicate, we innovate. Every product that comes out of Upper Carbon is the result of hands-on development, combining aggressive styling with performance-driven engineering.

From the street to the track, our parts are made for riders who want their bike to be as unique as their riding style.

What to Expect Before You Order

Premium carbon fiber should look incredible, fit with confidence, and come with clear expectations before you buy. Upper Carbon parts are designed around OEM-spec fitment where applicable, with some applications requiring transfer of factory grommets, latches, or mounting hardware. Production timing, pricing, and fitment expectations should always be clear before checkout.

  • Pre-drilled where applicable
  • Some applications require OEM hardware transfer
  • Clear production timing before purchase
  • Support available for fitment questions
