About Us
Diamond Bar Choppers has been involved with the motorcycle industry for 15 years. Diamond Bar Choppers started out as Bob's Harley Repair until October 2004, when we relocated to Diamond Bar and changed our name to Diamond Bar Choppers. We focus on performance work. If you want a fast and reliable motorcycle, we are the ones you want to see. We are a full service motorcycle shop specializing in Harley Davidsons, Indians, and many other brands. Whether you need an oil change, carburetor adjustment, or a fully customized bike built from the ground up, we will get it done. We get a lot of work referred to us from other bike shops in the area that send in problem bikes for diagnosis and repair. Bob has been a master mechanic since 1982.
