Dirty Bird Concepts has been at the forefront of the custom motorcycle industry for decades, pushing the boundaries of design and performance. Founded by legendary builder John Shope and carried forward by current owner Wyatt Miceli, Dirty Bird Concepts became a household name in the bagger and custom bike world, setting trends with bold, aggressive styling and cutting-edge parts. At the core of Dirty Bird Concepts is a team of skilled engineers, fabricators, and designers who are passionate about building the best products on the market.

As part of this next evolution, Dirty Bird Concepts has also acquired Speed by Design’s composite parts line, bringing even more premium custom options to our customers. This addition strengthens our lineup, ensuring that we continue delivering top-tier designs that enhance both the look and function of every build.
At Dirty Bird Concepts, we don’t just make parts—we create the future of custom motorcycles. Whether it’s our signature Dirtytail series, aggressive bagger designs, or premium composite components, we remain committed to providing riders with the highest-quality products on the market.
