Two motorcyclists have allegedly been caught filming themselves street racing along winding roads north of Sydney.
Highway patrol officers clocked the bikes travelling south on the Pacific Highway near Cowan at 140km/h in an 80km/h zone about 3.45pm yesterday.
They were travelling side-by-side in what police will allege was a form of street race.
Police stopped both bikes and spoke with the two drivers, men aged 49 and 47, and seized a video camera which had been fitted to one of the bikes.
"This type of idiotic behaviour is normally the domain of the young, so it is extremely worrying to see people with years of driving experience act in this manner," said Traffic and Highway Patrol Command's Operations Manager, Superintendent Stuart Smith.
