Police say speed was a factor in a motorcycle crash Friday afternoon. One man was killed in the single-vehicle accident.

Lieutenant Robert Savary of the Bath Police Department said in a press release that the report of a motorcycle crash came in just before 5:30. Sergeant Nathan Gould responded to the Wingfarm Parkway and found a motorcycle on its side in the road and the operator unconscious and slumped on the guardrail about 20 feet away from it. There was no passenger on the bike.

Police say Mark Lebourdais, age 52 of Bath was traveling West on Wingfarm Parkway when he failed to negotiate a curve. He then crossed into the oncoming lane and crashed into the guardrail on the opposite side of the road, throwing him from the bike. He was not wearing a helmet.

The crash is being investigated by the Bath Police Department but police say it appears that excessive speed was the primary cause. Police say there are no indications that drugs or alcohol were factors in the accident.
