Bolt Motorcycle Hardware is located on the beautiful central coast of California, where they design, assemble, package and supply hardware kits. It started in 1989 with a twelve-year-old boy who really wanted a motorcycle. He mowed the lawns, threw away the gravel. He and his father found a used Kawasaki KX80 in the newspaper, and after emptying his hard-earned savings account, his motorcycle was his. After finally getting his mother to ride with him within an hour and a half of Hollister Hills, it happened that in two minutes of the first KX ride, the rear axle fell out. The previous owner used the wrong hardware! Children's Day ended before it actually began. On the way home, he wondered how something so seemingly insignificant could have had such an effect on his day. Thus began a passion for reliable and suitable fasteners for motorcycles. Eleven years ago (and several other motorcycles), Bolt Motorcycle Hardware was born. In 2003, we released our first product, the Japanese Track Pack. Since then, we have created several other hardware solutions and our product line is constantly expanding. Our fasteners are tested and used at a professional level in supercross, motocross and ATV races. We carefully inspect new models every year to keep our hardware products current and usable.
