My father is a darksider
. Do I like it? No, but he is a grown man able to make his own choices. Of course in his defense; he does ride a Goldwing, pulls a bunkhouse camper, and he isn't exactly out carving up the corners.
Go back and look at the pics. Look at #3 He isn't leaned over very far and his footpeg is almost dragging.
#11 Look at the "S" curve directly in front of the rider; I think he tried to split the S curve then by crossing the yellow line.
#13 It would appear that he lost traction when he came back across the yellow. You can see either drag marks or tire spin starting form the other side of the yellow.
Either way...sucks to be him. Be careful folks
