A 24-year-old Leona Valley man was killed Saturday morning when he lost control of his motorcycle on southbound San Francisquito Canyon Road.

Officer Monica Posada of the California Highway Patrol identified the victim as Leonard Rohaley II.

According to the CHP report, Rohaley was riding a 2006 Yamaha R-1 sport motorcycle at a high rate of speed at 11:44 a.m. when he failed to negotiate a sweeping left curve near Stator Lane, about six miles north of Copper Hill Drive.

The motorcycle ran off the roadway and down an embankment. The rider was ejected, coming to a rest in a dirt ravine.

The CHP report said a witness and several passing motorists stopped to render aid and were administering CPR when Highway Patrol officers and paramedics from Los Angeles County Fire Station 156 arrived at the scene.

Attempts to revive Rohaley were unsuccessful and he died at the scene.

Posada said he was wearing a helmet and riding jacket at the time of the crash.

Although Posada could not confirm it, witnesses at the scene said Rohaley was traveling in a group with six other riders, and that he was going about 100 mph when he lost control of the bike.
