As Wall approached the S-curve, he moved from the slow lane to the fast lane, but didn't make the curve. The motorcycle hit the wall at about 130 mph. The man was thrown off his bike and came to rest in the fast lane. The motorcycle continued southbound for 1,000 feet before coming to a stop in a ditch.
Wall was taken to McKay-Dee Hospital in Ogden in critical condition. He was not wearing a helmet and suffered serious head trauma. He has since been upgraded to serious condition.
Wall had a suspended driver's license and an outstanding warrant. The investigation is continuing to determine if drugs or alcohol were in-volved.
Traffic was stopped for about an hour while a medical helicopter airlifted the man to the hospital.
