The solo-vehicle crash was reported on the ramp at about 2:05 a.m., according to CHP Officer Aaron Quistad.
The motorcyclist lost control of his vehicle on a right curve in the roadway and struck a concrete barrier wall, according to the CHP. The victim was ejected from the motorcycle and struck a concrete pillar, causing fatal head trauma.
The victim fell below the transition road and landed in a grassy area between the freeway and a California Department of Transportation yard, according to the CHP.
CHP officers arrived on scene and closed down the ramp for a little more than an hour, according to Quistad, who said the ramp was reopened at about 3:15 a.m.
