STANDING STONE TOWNSHIP - A man was transported by emergency medical helicopter to Robert Packer Hospital in Sayre after he was injured in a motorcycle accident Saturday afternoon on U.S. Route 6 in Standing Stone Township, authorities said.

The man was unconscious when emergency medical technicians arrived at the scene, said Wysox Fire Chief Brett Keeney.

The accident occurred as the man was driving the motorcycle east on Route 6, between River Road and Goff Road, state Trooper George Layaou said.

The man went off the south side of the roadway, and his motorcycle struck two of the concrete medians that had positioned off the south side of the road, he said.

State police at Towanda declined to release the man's name late Saturday night.

The accident occurred at a sharp left curve of the roadway, which the motorcyclist would have reached after traveling up a hill where rock cuts had been made in the hillside.

The man was not from the area, so it is possible that he was not familiar with the curve in the roadway, police said.

The trooper said that speed was a factor in the crash.

The motorcyclist was wearing a helmet at the time of the crash, police said.

There was extensive damage to the man's motorcycle, police said.

The motorcyclist was transported by ambulance to a field off West Valley View Road, near Claverack Pond, and then transferred to an emergency medical helicopter, Keeney said.
