When Kasandra gets off the motorbike, she hangs her helmet over the right rear-view mirror of the bike. Later, when Dude puts his helmet back on, Kasandra's helmet is still hanging there, but after the next cut, when Dude gets on the motorbike and starts the engine, Kasandra's helmet is now hanging over the left rear-view mirror. In the next scene, when Dude drives away, Kasandra's helmet is gone, but later, when she runs after him and gets on the motorbike, he hands her helmet to the back.
