Diamond Bar Choppers is a full-service motorcycle shop. It specializes in Harley-Davidson bikes and clones, but can accommodate most other domestic and imported makes. DBC excels at custom work and performance modifications. Standard mechanical maintenance and repair jobs are OK, too. Same-day service is available on most minor work. At the front of the shop, some motorcycle parts and apparel pieces are sold. Potential customers should note that DBC does not work on dirt bikes.
