Highway patrol officers continue to investigate both of these crashes.
One happened up near Shaver Lake, and the other was 25 miles away, just south of Millerton Lake.
Just before 3 on Saturday afternoon, the CHP says a 44-year-old motorcyclist was trying to navigate a curve in the road on Auberry Road west of Summit Mountain Road.
He drifted out of his lane and crashed into a metal roadway marker and guardrail, then flew off the motorcycle and died at the scene.
He was later identified as Christopher Garcia from Clovis.
About 5 hours later, a 21-year-old driver in a Toyota MR2 was making his way around a curve on Route 168 east of Auberry Road. He lost control and swerved into the opposite lane of traffic and collided with a pickup truck.
The man died at the scene. He was later identified as Jesus Meza-Leyva of Caruthers.
The driver of the truck did not report any injuries.
Authorities say alcohol or drugs do not appear to be a factor in either crash.
The CHP says both accidents appear to be the result of losing control on winding roads.
