A Maine man was critically injured Sunday afternoon in a motorcycle crash in Vassalboro.
39-year-old Andrew Olson of Augusta suffered serious head injuries when his bike went off Cushnoc Rd., and struck a guy-wire attached to a utility pole.
State Police Trooper G.J. Neagle says it appears Olson lost control on a curve, and that speed was a factor.
Olson was not wearing a helmet.
