In 1958, Resweber battled veteran racer Joe Leonard to win his first national championship. The 1960 season represented a great triumph for the Cedarburg "flyer" as he was called. Only two points behind Resweber, Leonard needed only to finish ahead of him to assure a tie for the title. Resweber took third place in one of the greatest races of his career, and won his third consecutive championship. On September 16, 1962, on the brink of becoming a five-in-a-row Grand National Champion, Resweber's career ended. During a practice, Resweber went down with three other riders. Jack Gholson, a long-time racing friend died in the accident. Resweber's injuries, a brain concussion, a broken neck, a broken chest bone, and six fractures of the right leg, left him in a body cast for nine months. Though many fans believed Resweber would eventually return to racing, he never did. He went to work for the Harley-Davidson Motor Company, machining special parts for racing machines until 1992.
