We have been selling Big Dog Motorcycle parts on ebay since 2003. We started as the original Big Dog factory liquidation outlet, then progressed to the exclusive contract buyer for all surplus parts from the factory including new overstock.
 When the company was foreclosed on in 2013, we purchased the remaining inventory and all of the original tooling from the bank. Since then, we have continued to manufacture new Big Dog Motorcycle parts with most of the original vendors using factory O.E.M. specs and materials. We have also upgraded some old parts and developed new parts in the manufacturing process.
