How easy is it for the radar guns to pick up on motorbike speed? I thought the guns need a large flat surface.
it depends how big the rider is… :hehe: 
i’ve been done with one before and from what i understand, despite evidence to demonstrate they’re flawed on motorbikes, the courts aren’t interested.
I’m still convinced i wasn’t going the speed they said I was, but there is very little you can do to prove otherwise as the policeman is an expert witness using approved equipment.
They were there again this morning. And there was also a big op on the approach to Parly Sq, but that seemed to be aimed at HGVs.
they are extremely hard to put on motorcycles despite what they may tell you. The visual sight often varies from the actual object by a couple of feet, and on a motorcycle that makes a huge difference.
They were on london wall westbound, just past moorgate yesterday, the one with the radar gun was hiding behind a lamppost.
I was giving the wavy hand on top of the helmet to oncoming biker and felt like a right twat.
