Welcome to Dubach Racing Development

We started Dubach Racing Development with the goal to produce the best exhaust systems and related mx products that actually make your bike run better, not different. I have worked with the best, tested virtually every motocross bike make over the past 30 years, and still work hand in hand with the Yamaha Testing division. Riding YZ’s and every other brand of motocross bikes, continuing to learn and develop motorcycles and moving DR.D forward is what I do. Throughout my career, I’ve been fortunate that my avocation has also been my vocation. We know the effort that must go into a product for it to perform at a level that exceeds, the admittedly, extremely good stock bikes and ATV’s. We put 100% effort into our products and constantly strive to achieve your business.
