I followed one of the fast guys out of the fast sweeper and followed his line through the u-turn. Coming into the slow right-hand uturn he crashed. I got on the brakes to avoid hitting him and lost the front at ~85mph. Sliding was no problem but when I hit the dirt I started to flip. Ouch.
The superbike is mostly okay - I need left footpeg and shift lever bar. I got pretty lucky that way.
For now I'm just relaxing and waiting for the abrasian pain to stop.
