(KMZA)--A Wamego motorcyclist suffered suspected serious injuries after he struck a semi-truck on K-13 Highway in Pottawatomie County late Thursday morning.

The Kansas Highway Patrol reports 47-year-old Delbert Hanson was southbound on a curve in the roadway when his Harley Davidson motorcycle went left of center, striking a northbound semi-truck.  The semi driver had made an evasive maneuver in an attempt to avoid the collision.

Hanson was airlifted from the scene to the University of the Kansas Hospital in Kansas City.

The semi driver, 24-year-old Wamego resident Alex White, was not hurt.

The Patrol says Hanson was not wearing a helmet when the wreck occurred shortly after 11:15 Thursday morning.
