And also, speaking as someone who raced professionally for Kawasaki for a few years in college...the rider is taking that turn completely wrong unless he's just about to switch sides for a chicade. His entire body should be in line with the bike, even if it's slightly off to the side. You're supposed to keep your core (from *** to face) parallel with the direction of the wheels. He has his body partially turned and it can cause you to loose traction, lose turn ability (by changing the center of gravity), or cause you to high-side if the brake is required.
