About us
Welcome to Billet Proof Designs—we’re glad you’re here. I’m Damian, founder of Billet Proof Designs and a lifelong rider. What started as a passion project between two friends has grown into a trusted source for premium motorcycle and powersports parts. For over 15 years, we’ve built this brand from the ground up with a small, dedicated team (Dan, Mervyn and Cam) that lives and rides the lifestyle we support. We don’t just sell parts—we use and ride with them.
Riding has been my therapy, my freedom, and my joy, and we know many of you feel the same. That’s why we’re committed to offering highly curated top-quality parts, great prices, and unmatched customer service rooted in real experience. When you shop with us, you’re not just upgrading your bike—you’re joining a community that shares your passion for the road. Give us a try; I promise we don't disappoint.
Thanks for being a part of our story.
Ride on and ride hard.
