The 63-year-old woman's identity has not been released. She was riding on the back of a 1997 Honda Magna driven by a 62-year-old Rancho Santa Margarita man, according to a CHP incident report.
A witness in a following car went to a U.S. Forest Service Fire Station around 4:40 p.m. Sunday to report that the woman flew off the bike about 13 miles east of the San Diego (5) Freeway, said Capt. Steve Concialdi of the Orange County Fire Authority.
The CHP report says the man driving the motorcycle failed to negotiate a turn while going 40 mph and hit the gravel shoulder. The woman was ejected as the motorcycle hit the guard rail.
