About Our Parts The vast majority of our parts are locally manufactured and distributed by DH1 Racing Products which is located in Sparks, Nevada. We have been creating and perfecting these parts for nearly ten years. We distribute parts wholesale to other retailers but continue to sell directly to the public passing the savings on to you. We stand behind our products because we not only make them, personally checking them individually before selling, but we also race with them. Whether you are a beginner working out in your backyard, or a professional in either motocross or desert racing, you can trust that our parts will help you ride better and safer. If it says DH1, it is a product you can rely on to get you across that finish line.
