A police operation aimed at cutting out nuisance motorbike riding near MFN in Shipley, Ilkeston, saw 80 riders stopped.
Operation SafeRide saw police check bikes heading to the venue in Long Lane.
The operation, held on Wednesday, April 22, came after concerns were raised about the roadworthiness of motorbikes and the manner of riding.
A total of 80 riders were stopped during the evening, with 65 motorbikes found to have defects or document offences.
Two motorbikes were found to be so defective that immediate prohibition orders were made, meaning they could not be ridden off.
The safety checks were part of a multi-agency operation between Derbyshire Police and the county’s road safety partnership.
PC Adam Titterton, who organised and led the Ilkeston Operation SafeRide event, said: “We welcome all motorcyclists to visit Derbyshire as it’s such a beautiful county. However, we want the roads to be safe for everyone.
“Operations such as this are all about ensuring people are sticking to the law and we will take action against any road users who break it.”
