Two people were seriously injured when a motorcycle they were on left the roadway on Lewiston Road in Oakfield and struck a retaining wall in a yard.
Contrary to an earlier report, no vehicle was involved.
Sgt. Matt Wikowski, State Police, said at this stage of the investigation it's not clear why the driver lost control over the motorcycle.
The driver and a female passenger were both ejected from the bike. The driver was transported to ECMC by ground ambulance and the female was flown to ECMC by Mercy Flight.
Oakfield Fire and Mercy EMS assisted at the scene.
