"The motorcycle did not have number plates attached, it was uninsured, and had been unregistered since April 2019."
Acting Officer in Charge of Traffic Operations, Sergeant Jayde Evans said the boy was fined a total of $4069.
"Motorcyclists are among the most vulnerable users on our roads. The behaviour exhibited by this rider greatly increases the risks," Sergeant Evans said.
