(KMZA)--A motorcycle crash on a Pottawatomie County road early Sunday evening claimed the life of a Centralia man.

The Kansas Highway Patrol says killed in the crash on Carnahan Road, south of Olsburg, was 42-year-old Justin Smith.

The Patrol says Smith was northbound on his Harley Davidson motorcycle when he failed to negotiate a curve for an unknown reason.  His motorcycle crossed the center line, went left off the roadway and struck a ditch, causing the vehicle to go airborne.

Smith was ejected from his motorcycle and pronounced dead at the scene.

The Patrol says Smith was wearing a helmet when the crash happened shortly before 5:40.
