The speed camera commission says motorcycle riders are escaping fines because some cameras cannot detect rear number plates.
The commission says almost 20,000 speeding riders did not receive fines and demerit points in the past three financial years.
More than 200 of those were caught exceeding the speed limit by 45 kilometres an hour or more.
The commission says most mobile speed cameras in Victoria cannot detect rear plates.
But John Eacott, from the Victorian Motorcycle Council, says the technology is available and should be used in Victoria.
"It's being used in Western Australia right now and is proving to an absolute success. We welcome any road safety initiative that benefits all road users," he said.
Meanwhile, police are cracking down on pedestrians who break the law.
Operation Halo will target people disobeying traffic lights and not following road rules when using crossings.
Police cautioned and fined and more than 130 people when they ran a similar operation in February.
