(KNZA)--A Winchester man was injured Monday evening after crashing his motorcycle on a Jefferson County road about two miles west of Perry.

The Kansas Highway Patrol says 23-year-old Colby Peck was northbound on Thompsonville Road when, for an unknown reason, he failed to negotiate a curve. His Harley Davidson motorcycle went off the side of the road and overturned, ejecting Peck.

He was transported to Topeka's Stormont-Vail Hospital with suspected serious injuries.

The Patrol says Peck was wearing eye protection, but wasn't wearing a helmet when the crash occurred shortly before 7:00.
