THE owners of these distinctive stolen motorbikes (pictured) are being urged to come forward.
Police recovered the two motocross motorcycles, one KTM and one Kawasaki, during a raid at a property in Meadowbank last November.
Officers have been unable to trace the owners despite extensive enquiries, a South Yorkshire Police spokeswoman said.
She added: “The bikes have some distinctive markings and police want to hear from you if you recognise them.”
Anyone with any information should call 101 or email firstname.lastname@example.org, quoting incident number 620 of March 23.
