“It is completely unacceptable behaviour,” they said.
“Police regularly follow up to hold those involved to account and either issue them with infringement notices or charge them with driving offences but the message does not seem to be getting through.
“It is illegal to ride a dirt bike on the road unless it is roadworthy with a current warrant and registration. Anyone riding a bike with an engine capacity above 50cc needs to have a motorbike licence.”
Police also asked parents and caregivers to take responsibility for the actions of the riders, some of whom were young.
“The last thing we want is to have one of these riders cause a crash and injure or kill a member of the public.”
Police advised members of the public who come across these riders to keep themselves safe and call police when safe to do so.
