Description
A derby cover does more than protect your primary cover from road debris and UV damage—it’s a critical maintenance component that extends the life of your engine’s primary case seal. The Drag Specialties Wrinkle Black Derby Cover combines classic aesthetics with reliable die-cast construction, giving your Big Twin or Dyna a refined finish while keeping contaminants out where they belong.
This bolt-on cover installs quickly with included mounting hardware and delivers that understated, factory-quality appearance that separates a well-maintained machine from a neglected one.
