A 22-year-old woman was hospitalized in serious condition Friday after she crashed her Harley Davidson motorcycle into a friend's motorcycle, CHP and hospital officials reported.

Kimberly Ann Bailey, 22, of Auburn, was riding her motorcycle on Penn Valley Drive south of Highway 20 at 12:56 p.m. Thursday when she failed to slow down to avoid hitting another bike ridden by Garrie L. Horton, 48, of Sacramento, California Highway Patrol Officer Jeff Pingree said

Bailey was ejected from her motorcycle and sustained major face and head trauma, Pingree said.

Bailey was transported by helicopter to Sutter Roseville Medical Center, where she was in serious condition Friday afternoon, hospital spokeswoman Liz Madison said.

Horton was not injured, Pingree said.

Both motorcyclists were wearing helmets, and alcohol was not a factor in the crash, he said.

It is unknown why Bailey failed to slow down, Pingree said.
