A Bend man was killed Saturday afternoon when he lost control of his motorcycle while maneuvering the southbound off-ramp from the Bend Parkway on to Butler Market Road.  Police reports say Scott David Parsons, 49, was thrown from the bike and landed on some large rocks.  He was pronounced dead at the scene.  Initial findings reveal that Parsons was following another motorcycle southbound on the Parkway and both left the parkway. For unknown reasons, he lost control of his motorcycle, left the road and was thrown to the ground. The investigation is continuing to determine the cause of the crash. No other vehicles were involved and the other rider was not hurt.
