WARNINGS have been issued to mini-motorbike owners after 140 were seized in West Yorkshire in the last two months.
Insp Mohammed Rauf, of Huddersfield North Neighbourhood Policing, said there were particular problems in the Ashbrow area.
His officers have confiscated three bikes in the last fortnight.
“We will continue to clampdown on those who use them illegally,” he said.
“What people need to remember is that there are strict guidelines on their use.
“They are essentially motor vehicles and in order to use them on a road, a rider must be over 16 and hold a driving license for that class of vehicle.
“It must also be taxed, insured and comply with construction and use regulations.”
Like cars, mini-motorbikes are subject to MOT regulations.
They must have a number plate and adequate lights.
Riders can use them on private land, with the consent of the landowner.
The bikes cannot be ridden on paths, verges or in public parks.
Insp Rauf added: “As far as the law is concerned it is almost impossible for most of these vehicles to fulfil the criteria.
“Some people may think riding them off-road is the answer, but what they do not realise is that a road includes the pavements, verges, footpaths and bridleways.
“Even if the vehicle is used on private land, the rider must have the land owner’s permission.”
Officers have off-road bikes which can be used to track bikes being used illegally and head-cameras to identify offenders.
Insp Rauf’s warning comes after three-year-old Trimayne Madourie, from Bradley, was injured after crashing his dad’s mini-motorbike on Easter Sunday.
He said the bike was not one of those seized.
But he said bikes were often a source of anti-social behaviour.
“If they are taken away from the road it generally causes annoyance, alarm and distress to local residents,” he said.
“Anyone found to be using these vehicles in an anti-social or unlawful manner will have the vehicle seized and will have to pay the recovery and storage charges to have the vehicle released.”
The rider can also be prosecuted for a road traffic offence.
Bikes that are confiscated are usually scrapped.
Owners who can prove they are legitimate can get them back.
Insp Rauf said: “If you have one of these machines or are planning on buying one, make sure you know the law and adhere to it.”
