Police on Merseyside are asking bikers heading for the TT to fill in a form that'll help trace their machine if it's stolen.
Operation Needle is an annual initiative which aims to prevent bikes being taken as they pass through Liverpool.
Motorcyclists give details of their bike's make, model, colour, registration and Vehicle Identification Number along with contact details.
If their bike is stolen and recovered officers say it'll help them reunite the bike with its rightful owner.
