I was riding home yesterday on the A13 heading to the Rotherhithe tunnel, and there were a couple of ambulances and police cars blocking the road, letting traffic round gradually, one direction at a time. As I went by one of the police was wheeling what looked like a blue SV650 Sport (or similar, half-faired) off the road, and they were putting the biker on a board.
Didn’t see any more than that, hopefully it was a precaution with the board, the bike didn’t look too damaged at all. There was a car involved but I didn’t really take much more in.
