The accident happened around 11:41 a.m. about a mile west of Skyline Boulevard, according to CHP Officer Art Montiel. The motorcyclist, identified Monday by the San Mateo County Coroner's Office as Matthew Wong of Campbell, was traveling westbound when he lost control of his bike as he was navigating a left turn in the road, Montiel said.
Wong went 40 feet down an embankment and was pronounced dead at the scene by emergency personnel, Montiel said. It does not appear that drugs or alcohol were factors in the crash.
One-way traffic control was implemented after the accident, and an SMC Alert was issued just after 12:30 p.m. The roadway fully reopened to traffic around 3:30 p.m.
Witnesses are encouraged to call Officer David LaRock at 650-369-6261 with any additional information.
