My husband broke his radius, about 12 years ago. He was in his late 40s, and in serious good shape. In fact, he broke his other wrist too, but it was only a hairline fracture. So, screws and plates in one with a cast, and a splint on the other. He had the cast on for about 4-5 weeks, had OT, and the pins were out a couple of weeks later. He resumed riding after 6-8 weeks? It was fall by then, and it was very painful for him, but he did it.
