Biker down in Tradouw's pass

My sister in law just phoned to ask if I know the guy who fell in Tradouw's pass this afternoon. They were the fisrt one's on the scene and drove back to the rider's buddies who were waiting for this guy down the road. Seems like he slipped around the corner and went over the barrier...bike still on the road and he down over the edge 50-75 metre drop! Apparently the guy is from Mosselbay...
