Officials say 67-year-old Tony Weber of Yuma, Colorado, crashed Friday near Johnson Siding. Weber lost control of his motorcycle while approaching a bridge, slid into a ditch and struck a barbed-wire fence.

The South Dakota Department of Public Safety says Weber died at a Rapid City hospital on Sunday. He was not wearing a helmet.

The 10-day rally wrapped up Sunday. Four people died in crashes at last year’s rally. Another person died at this year’s rally from a suspected case of carbon monoxide poisoning.
