It's like a dance.
Effortless, almost gliding, Miss Leah Petersen guns her bike around the rooftop of the carpark at Turf City, performing stunts with ease.
Wheelies, burnouts, bunnyhops and drifts - manoeuvres usually handled aggressively, but here, with a sense of calm.
Clad in her trademark purple racing jacket and riding her purple Kawasaki Ninja, Miss Petersen shows why she is the world's top female sportbike free-style rider.
Don't let the girly colours fool you. Like the similarly hued Hit Girl from the Kick-Ass films, her stunts are hardcore, nothing for the faint of heart to attempt.
Miss Petersen is here as part of the 2013 Motul Bike Festival, which also counts as the first leg of her Asia tour.
While no one can knock her aptitude for dangerous stunts, it has to be said that she can also make heads turn with her looks.
It's not just that she is a striking figure in her bike leathers. Off her bike and without her helmet, the Los Angeles native, who stands about 1.8m tall, with long blonde hair and a slender figure, could easily be a model.
