Derby & Inspection Covers

Harley-Davidson derby covers, also known as clutch inspection covers, attach to the primary chaincase cover and provide access to the clutch inspection area. Harley-Davidson service documentation uses both “clutch inspection cover” and “derby cover” terminology and identifies the cover, gasket, screws and washers as related service components. This category includes Harley-Davidson derby covers, smooth and finned covers, billet designs, clear inspection covers and replacement covers for a wide range of Harley-Davidson motorcycles.

The product selection covers Harley-Davidson clutch inspection covers, primary inspection covers, derby cover gaskets, cover bolt kits, mounting hardware and specialty designs from brands including Barnett, Trask, Joker Machine, V-Twin, Covingtons, Roland Sands Design, Performance Machine, Rekluse, Feuling, Arlen Ness, Paughco, Thrashin Supply Co. and others. Designs include chrome, gloss black, wrinkle black, polished, machined, finned, smooth, clear, engraved and custom-styled covers. The category also includes model-specific Sportster inspection covers and older primary inspection covers for classic Harley-Davidson applications.

Applications span older FL, EL, UL, XL, FX, FXR, Sportster, Dyna, Softail, Touring, Big Twin and Milwaukee-Eight motorcycles, with different cover shapes, mounting patterns and primary-cover configurations across model generations. Harley-Davidson derby cover gaskets are available separately for applicable assemblies and Harley-Davidson service information notes that the gasket should be inspected and replaced when required after cover removal. The range also includes derby cover bolts, primary and inspection-cover hardware and related cover components for completing different primary-cover setups.
