Ten motorbikes have been seized by police taking part in an eight-week operation to tackle the use of off-road motorbikes in parts of South Yorkshire.
Officers have been issued with their own off-road bikes so they can respond quickly to those breaking the law.
The force said the riding of motorbikes was not permitted on public land in South Yorkshire.
Ch Insp Stuart Walne said they were pleased with the results in the first three weeks of the operation.
Ch Insp Walne, who is the force's head of road policing, said: "Our communities have told us that there are problems in some areas with off-road and nuisance motorcyclists.
"We know where these offences are taking place and are working proactively in these areas with good results.
"We will do what we can to apprehend those who continue to break the law."
He added that offenders who were caught faced a fine and having their bike seized.
