More than 50 Commanchero members were seen by police to be riding in formation on the New England highway at about 10am near Qurindi in the states west.
A Ford falcon travelling at more than 150km/h was seen to overtake the group of bikes on the crest of a hill and was heading towards an oncoming police car which had to swerve.
Police allege the car, one of a number of support cars with the Outlaw motor cycle gang was detected by radar to be going at 156kmh in a 100kph zone.
Senior police have refused to comment on what the group were doing travelling in such a large number in the NSW countryside.
The groups self-proclaimed leader, Mark Buddle was recently arrested on the Gold-coast and extradited to Sydney to face assault charges.
Police eventually caught the speeding vehicle and spoke to the driver who held a current Northern Territory driver’s licence.
He was issued with a court attendance notice for dangerous driving, exceed speed-over 45kmh and overtake when unsafe. His driving rights in New South Wales were suspended and he is due to appear in Tamworth Local Court on February 11 .
