Our HistoryThe origins of Fat Katz Inc. date back to 1979, when founder Don Baumunk began fabricating roll cages, suspensions and aluminum bodies for off-road race cars under the name “D & D Metalworks”. In the racing industry, Don did work for such names as Don Prudhomne, Ed McCullouch, Joe Amato, and Malcom Smith. In 1989, Don relocated to Grass Valley, CA where he was introduced to a new business opportunity. The aftermarket gas tank business for the motorcycle industry was a fascinating chance for Don to be creative, exercise his skill and implement his fabricating experience into an exciting new industry. D & D Metalworks became a world leader in hand-made, custom-formed gas tanks for the motorcycle industry. Baumunk took great pride in producing these fine, hand-crafted aluminum and steel gas tanks.
Today, Don Baumunk operates under the name “Fat Katz Inc.” — his gas tanks are among the very best in the world, and are still hand-made in Grass Valley, California. Where did the name Fat Katz come from? Darlin Baumunk, Don’s wife, came up the name when she recognized that everything D & D made had to be “Fat”. They started to produce the “Fat Katz Kustom Aluminum Tankz”, and the rest is history. In the year 2000, Baumunk renamed the company to reflect the “Fat Katz” image and a new era began. It was also the year that Don Baumunk began to produce custom, hand-made fenders for the American motorcycle industry. These hand-made, cold rolled, 13-gauge steel fenders have made a great impact on the industry. Fat Katz models, such as the “Vegas” fender, have become icons in the industry.
Tank and fender building is an artform. After decades of experience, Don and his metal artists are the best in the business. Many Fat Katz products have been featured by the best bike builders across America (see our Gallery) and have been featured on the Discovery Channel show American Chopper.
