There was a biker down on A13 earlier today, around 14:00.
I hope they’re safe, couldn’t quite tell what happened and where was the biker.
Here’s the aftermath if anyone’s interested:
Lots of signs on M25 saying road closed. That does not sound good.
Looks like the guy at 0:20 is photographing evidence. Numbered cones on the road side, bike some 70-80 yards down the road… Not looking good indeed.
Yeah. Drove past the other way. The investigation crew were out. A13 was shut off completely. Didn’t see any other vehicles. Just the remains of the bike scattered across the road… 
Glad to see the biker is stable.
