An Inverell teenager has received serious head and chest injuries after coming off his motorbike during bad weather.
The 17-year-old man was reportedly riding along Rifle Range Road in Inverell before 3pm on Saturday when he came off the bike.
"[The] male was riding an unregistered motorcycle on Rifle Range Road, Inverell where it appears, he lost control and was ejected from the motorcycle.
"The young man was located by friends and emergency services were contacted," Chief Inspector Rowan O'Brien said.
Emergency services attended the scene to treat him when they called for further assistance from the air.
The Westpac Rescue Helicopter team, however, could not get to the injured man due to low fog and cloud preventing the chopper from landing.
"Overhead the scene the weather was such that the helicopter could not get to the scene due to low fog and cloud and had to abort the task. The helicopter has since returned to base," A Westpac Rescue Helicopter Service spokesperson said on Saturday.
He was taken to Inverell Airport by ambulance and transported to Armidale hospital where he was then airlifted to Sydney in better weather conditions.
"He remains in a critical condition at Royal North Shore Hospital suffering from facial injuries, suspected spinal and internal injuries," Chief Inspector O'Brien said.
