Timer Cover. Fits '04-later XL, XR and earlier models with horizontal holes on timer cover. The famous Harley-Davidson #1 logo with a sinister twist. Machined from billet aluminum, these covers feature domed surfaces that are polished and black anodized to a rich satin sheen, and then re-machined to expose the raw aluminum. The resulting high-contrast design complements both polished and painted engine finishes.
