...all my bikes are registered as Historic but I still have them all MOT'd each year 😁😁😁
Is there a reason for that Julie? I've had blue lights behind me twice and when I spoke to them they tell me my last MOT was in 2019, I had to explain!
Then they come out and have a look around the bike, half the time I wonder if that's why they really stopped me. 
A lot of Coppers are bikers or petrol heads.
When I worked foot patrol in Derby I used to stop an unusual sports car that had Irish Plates.
It would head up Ashbourne Road towards Mackworth most Saturday nights in the early hours.
It was an unbadged prototype DeLorian with a 6 cylinder Renault engine iirc.
The driver showed us under the bonnet etc, he told us it looked fast but wasn't.
He did tell us it was difficult to keep clean as the SS bodywork on the prototype was a sort of brushed unsealed finish that rain spotted badly.
