A Redmond-area man was seriously injured Friday evening when his motorcycle traveled off Kline Falls Highway about one mile south of Eagle Crest Resort and struck a mailbox. An Oregon State Police report says around 7:30 Friday night, Trooper Scott Sogge, responded to a call that a 2006 Harley Davidson motorcycle driven by Michael Lee Dyer, 48, from Redmond, was northbound on Kline Falls Highway when it went out of control on a curve. He traveled off the side of the highway for about 150 feet in the ditch before hitting a mailbox. Dyer was transported by Airlink to St. Charles Medical Center in Bend by with serious injuries. The report says speed does not appear to have been a factor in the crash. OSP is continuing the investigation.
