Each piece is individually hand cast from solid bronze, by me, in my studio at the Hot Shops Art Center in Omaha, Nebraska.
I can make this design as a derby cover for Harley-Davidson motorcycles, a derby cover for Thunderstroke equipped Indian motorcycles, and an air filter cover for Arlen Ness Big Sucker style intakes.
Production lead time is approximately eight to 12 weeks.
More On My Fortis Fortuna Adiuvat Design
Fortis fortuna adiuvat is a Latin proverb that translates to “Fortune favors the bold” or perhaps “Fortune helps the brave.” It encourages taking risks and acting with courage, suggesting that luck tends to reward those who are daring rather than hesitant.
The phrase first appeared in the Roman playwright Terence’s comedy Phormio (151 BCE), where a character says, “Fortes fortuna adiuvat” to imply that boldness invites good fortune. It was later echoed by Virgil in the Aeneid (c. 19 BCE) as “Audentis fortuna iuvat” (“Fortune helps the daring”). Over time, it evolved into a motivational motto, used by figures like Pliny the Elder during the eruption of Mount Vesuvius in 79 CE.
In current times, Fortis Fortuna Adiuvat gained wide recognition in the John Wick movies through his back tattoo.
Ever since I saw that image on the screen watching the first John Wick movie, I knew I needed to create a Fortis Fortuna Adiuvat design for my catalog. I thought about replicating the praying hands and cross design, but wanted to come up with something different and unique.
The sword through the skull symbolizes triumph over adversity, or even triumph over death itself. That felt like the perfect concept to combine with fortis fortuna.

What's Included
In addition to the derby cover, I include a James brand gasket (for certain sizes, where required), and black oxide coated mounting bolts. Feel free to use your existing mounting bolts if you prefer, but I like the look of the black oxide against the bronze patina.
Lead Time
All custom derby covers are made to order. Approximate production lead time is eight to twelve weeks, but is not guaranteed. If you have a situation (an upcoming ride, an event, etc) that means you need it sooner, please contact me first and I will see what I can do. Please understand that I really do make these by hand in my own shop. Bronze art casting will always have a certain failure rate, and I will not ship a custom derby cover I am not proud of.
Derby Cover Sizing
I support six different derby cover sizes, covering all Big Twins and most Sportsters made since 1970. Complete details on derby cover sizing are located here. If you are unsure of which one you need, give me a call at 402 321 9639. We'll get it worked out.
Maintenance
If you select either gloss of matte 2k clearcoat, your derby cover is maintenance free. Just wash with the same mild soap you use on the rest of your motorcycle, and dry with a soft cloth. Do not use polishing compounds or other abrasives on your clearcoated derby cover.
If you select a natural bronze finish, your derby cover will darken and patina with age. If you want to maintain its original appearance, you will need to polish it regularly (Brasso works well), and apply a coating of paste wax.
