FOUR motorbike accidents in the Clarence Valley have kept both the road and air ambulance services busy.
The mayhem began on Saturday when a man riding with a group of friends about 20km north of Dundurrabin hit a rock cutting travelling about 90kmh.
Grafton paramedics reached the man, who was from from Toowoomba, about 1pm, stabilised him and took him by road ambulance to Coffs Harbour Hospital.
Later that night paramedics were called to a single bike accident on the Coaldale Rd where a man had come off his bike, breaking a leg and causing other injuries.
The Westpac Rescue Helicopter airlifted him to Lismore Base Hospital.
Around noon yesterday a Sydney rider hit the wire centre dividers on the Pacific Highway just north of Post Office Lane, Ulmarra.
Paramedics said the impact tore open his bike helmet and inflicted severe facial injuries. He also broke his arm in the crash.
He was airlift in a serious, but stable condition to Lismore.
About the same time paramedics attended a dirt bike crash on a property at Lanitza where a 10-year-old boy was thought to have injured his neck.
The fears proved unfounded and he was treated for minor injuries.
