A fuel cap sits on top of the tank like a crown on a queen's head. Have you ever seen an uninspiring, plain, and ordinary crown of the queen? Of course not. That's why Performance Machine thinks Harley-Davidson® motorcycles need to be honored with a custom crown for their fuel tank. CNC-machined from aircraft-grade aluminum, unique Apex vented fuel caps are an instant custom addition to your bike—and will complement the matching dash inserts and ignition covers, if you choose to carry the theme throughout. Apex fuel caps are available in Black Ops, Chrome, and Contrast Cut finishes.
