Welcome to Billet Proof Designs – your home for top-quality aftermarket motorcycle parts and a haven for fellow riders who live and breathe the thrill of two-wheels.

I'm Damian, the founder of this passion-driven venture, and I'm here to share with you the heart and soul of what makes us who we are.

For over a decade and a half, Billet Proof Designs has been more than just a company – it's a labor of love, a testament to the enduring spirit of motorcycle enthusiasts. With a small but dedicated team consisting of myself, Damian, along with Dan, Mervyn, and our part-time extraordinaire Cam, we've nurtured this business from the ground up. We don't just sell parts; we live and ride with the very products we offer.

I've personally spent four decades enjoying what motorcycles have to offer. Motorcycles have been my escape, my therapy, and my unyielding source of happiness. The roads and trials have been my confidant, witnessing my thoughts and dreams unfold as the miles rolled by. It's this unbreakable connection to the world of motorcycles that led to the birth of Billet Proof Designs.

I just bought my first bike and was looking to do some custom modifications. Damian is very knowledgable and a pleasure to work with. He helped me design exactly what I wanted. I would recommend Billet Proof Designs to anyone looking for that custom look!

Motorcycle Parts, Gear,
and Accessories for All Riders

First and foremost, we are riders helping other riders. We are here to offer you the custom motorcycle parts and gear you need, when you need it and at a price that’s better than the rest. We are expert product curators; instead of offering an overwhelming number of parts in each category, Billet Proof offers carefully chosen brands, parts, gear and apparel. Billet Proof Designs was founded due to the frustration with the lack of customer service in the online, aftermarket power sports market. With a passion for all things motorcycles, Billet Proof Designs started with a primary focus on two goals: excellent customer and top quality products. Our goal is to provide you with an excellent shopping experience before, during, and after your purchase.
