Lately I keep seeing more and more brass motorcycle parts. It’s almost enough to make me build a steampunk chopper. These gas caps from Lowbrow Customs come in brass or aluminum, and they’re a quick way to add a nice touch to your Harley-Davidson’s gas bag. The Domed, Dished, and Banded style gas caps are precision-machined out of solid aluminum ($39.95) or brass ($59.95) and paired with an injection molded base and gasket that fits 1996 and later Harley-Davidson Big Twin and Sportster motorcycles, as well as most custom gas tanks.

At 2 1/2 inches in diameter, these vented gas caps are slightly smaller diameter than a stock H-D gas cap for that custom look and feature a knurled band for easy tightening and removal, with or without your gloves on.
