id bet over 200 riders have been down on that road in total. I did stop and look over this scene including the bike and talked with the rider. This particular turn has a driveway that intersects (although there was no traffic in the driveway at the time) and has a slightly reducing radius...i rider the road in the opposite direction so that turn is a left hander for me...but it was clear to me what happened...

he went in hot, but was starting to turn the bike...realised he was too hot and rolled off the gas/applied fromt brake to scrub speed...trail braking may have worked if he had the right finesse, but being 2-up im sure the weight transfer on the front end overrode the grip of the tire....CRASH....
