Arlen Ness Derby Covers

4 products — part of all Derby Covers

Arlen Ness derby covers are among the most recognised primary side accessories in the Harley-Davidson custom scene, carrying the billet aluminium aesthetic that defined the brand from its origins in San Leandro in 1970. The range spans standard five-hole primary fitments on 1999–2017 Dyna, 1999–2018 Softail, and 1999–2015 Touring models, alongside narrow profile primary applications on 2016–2025 Touring and Trike platforms — direct cross-references against the canonical fitment data Harley-Davidson workshops use. Coordinating inner primary covers and inspection covers from Arlen Ness are also available, enabling a consistent finish across the entire primary side without mixing brands. Now run by Cory Ness out of Dublin, California, the brand still makes parts that carry genuine custom heritage rather than just the aesthetic. Available through Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds. Browse the full Arlen Ness Derby Covers range below.
