I went on my first group ride (4 bikes) yesterday and one of our guys went down and was killed. I was the 4th rider and the rider that went down was in the number 3 position. He had been riding for a couple years and just went through the advanced MSF course a couple days before. We were on 2 lane road with curves on a downgrade coming out of the mountains. Rider 3 took one of the curves too fast and paniced. He put the bike upright and tried to brake instead of leaning through the curve. But he was going too fast and hit the curb. He flew off his bike and hit a guardrail. His head hit one of the vertical guardrail posts and his helmet actually got tore off his head (Seems like he did not have it strapped on right or maybe it was too big for him, don't know). He ended up on the sidewalk and when I got to him he was unconcious and his eyes were open. Rider 2 turned around and came back. Rider 1 came back a few minutes later. Rider 2 checked his pulse and breathing (very weak) and loosened his jacket while I called the police. He had no obvious trauma, was not bleeding anywhere, and was breathing so we did not move him or touch him. That is such a helpless feeling. He just layed there for 15 minutes until the ambulance showed up, we couldn't do anything for him. The ambulance came and took him away. We spent the next 2 1/2 hours at the accident scene trying to explain what happened to the Japanese police. When we got to the hospital he in surgery for a massive brain hemmorage and internal bleeding. We saw his wife at the hospital and after a while we left the hospital and rode home. Apparently he died in surgery while we were riding home. This was a very traumatic event and I haven't been able to sleep for 2 nights now. That was a bad day for riding, a Japanese motorcyclist was killed that same day on the same road. EVERYONE BE CAREFUL OUT THERE!
