Two people are recovering after a motorcycle crash this morning near Wahiawa.

Callers reported the motorcyclist, carrying one passenger, ran into a guardrail about two miles south of Poamoho Street on Kaukonahua Road shortly after 10 a.m., police said. The male driver was taken to the Queen’s Medical Center in critical condition, but was later upgraded to serious condition, police said. A female passenger was in serious, but stable condition. 

Police closed Kaukonahua Road for about 2 1/2 hours to investigate.

The road is notorious for motor vehicle accidents, particularly along its S-curve.
